Founded in Indianapolis by a motorsports engineer with roots in Formula 1 and CART racing, Zipp brought aerodynamic science from race cars to bicycle wheels before wind tunnel testing was standard practice in cycling. Today, the lineup ranges from the 303 SW — a high-performance tubeless wheelset for riders who want proven Zipp technology without the flagship price — to the full NSW series: the 353, 454, and 858, each representing the current peak of Zipp's aero engineering. Whether your roads are smooth tarmac or something more demanding, there's a Zipp wheel built for them.\u003c\/p\u003e\u003c\/div\u003e","products":[{"product_id":"zipp-303-nsw-carbon-tubeless-rear-wheel","title":"Zipp 303 NSW Carbon Tubeless Rear Wheel","description":"\u003cp\u003eWhile the Zipp 303 NSW is an expansion of the NSW line. They needed to  push farther, and the result is this 303 NSW Tubeless Carbon Clincher. It’s faster  and more flexible than the Firecrest, and the 303 itself is the depth and  weight that appeals most to all-round riding, light enough for extended  climbing, deep enough to speed on the flats.\u003c\/p\u003e\n\u003cp\u003eTwo things that are different right away are the new 19mm internal rim  width and the tubeless channel. With the 19mm size, they’ve optimized the rim  for 25mm tires. The tubeless channel means you have the option to run either  tubed or tubeless tires.\u003c\/p\u003e\n\u003cp\u003eThe 19mm width dictates a different rim shape than Firecrest. The depth  remains at 45mm, the brake track at 26.4mm, but the widest spot is 26.5mm a bit  of the way down the rim wall. This is to make sure 25mm tires are the most aero. \u003c\/p\u003e\n\u003cp\u003eThe rim comes with Zipp’s ABLC SawTooth   dimple pattern. It  improves aerodynamics in “no wind” (aka headwind) situations, but it’s greatest  strength is reducing loads created by crosswinds. You’ll have no concerns  piloting these wheels on gusty days, even if you’re small and riding aero bars.  It’s almost like a traditional box-section clincher. Overall, the wheel is  faster in all wind conditions.\u003c\/p\u003e\n\u003cp\u003eThe  brake track is Zipp’s ShowStopper textured braking surface. This is the 317  curved, vertical grooves on each side of the brake track that help move water  off the surface and reduce stopping distances.

The flanges are designed to be as  light as possible without sacrificing strength. The rear hub utilizes Zipp’s  Axial Clutch pawl mechanism, which reduces drag when coasting. The mechanism is  on three cassette body choices: a SRAM 10\/11-speed cassette body, a  Campagnolo-compatible 10\/11-speed body, and or a SRAM XDR driver body for  wider-ranging cassette options, including 1x 10-42 cassettes.

At the shallowest rim depth in the NSW family, the 202 NSW is where Zipp’s aerodynamic engineering meets a relentless focus on weight savings, and the result is a rear wheel that changes how a climbing bike feels under power. This is the wheel Zipp calls the fastest carbon clincher they have ever made, and for riders who measure their rides in vertical meters, that claim carries real weight.\u003c\/p\u003e\n\u003cp\u003eWhat separates the 202 NSW from other lightweight carbon wheels is how Zipp has approached aerodynamics at this rim depth. The SawTooth Technology — an evolution of Zipp’s signature ABLC (Aerodynamic Boundary Layer Control) dimple pattern — applies textured nodes in 12 discrete sections across the rim surface. These dimples manage how air detaches from the shielded side of the rim in crosswinds, reducing the lateral forces that make shallow wheels feel unstable on gusty days. Because this is a disc-brake wheel with no brake track to interrupt the rim surface, the ABLC dimples extend all the way to the rim edge, giving the aerodynamic treatment more surface area to work with. The 28.9mm external width and 21mm internal width mean you can run 28mm or wider tires — the sweet spot where the 202 NSW is designed to perform its best — with a planted, confident feel through corners at speed.\u003c\/p\u003e\n\u003cp\u003eThe Cognition rear hub is its own engineering story. Zipp replaced the traditional pawl-and-spring freehub mechanism with an Axial Clutch system that uses two precision MIM (Metal Injection Molding) ratchet rings — one mated to the freehub body, one to the hub shell. These rings engage laterally rather than radially, and instead of steel springs holding them in contact, Zipp uses magnets. The result is noticeably lower friction while coasting, so the watts you put in on the climb aren’t quietly bleeding away through the hub when you ease off. Engagement is fast, the freewheel sound is smooth and quiet, and the whole system is designed for long-term reliability with fewer moving parts to wear. Laced to 24 Sapim CX-Ray bladed spokes in a two-cross pattern with Sapim Secure Lock nipples, the build is both light and laterally stiff — exactly where you want it for out-of-the-saddle efforts on steep grades.\u003c\/p\u003e\n\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eClimbing Without Compromise:\u003c\/strong\u003e The 32mm rim depth keeps weight low where it matters most — at the outer edge of the wheel — while still providing meaningful aerodynamic benefit over a box-section rim.

It is a carbon road wheel that takes aerodynamics seriously, but it is also built to handle roads that most aero wheels would refuse. The 650b diameter makes it at home on mixed-surface rides, gravel detours, and technical terrain — while the Firecrest rim profile keeps the focus squarely on speed and stability where the pavement is clean. This is a wheel that broadens what a carbon tubeless wheelset can be asked to do.\u003c\/p\u003e\n\u003cp\u003eZipp's Firecrest rim geometry is the foundation here. The toroidal shape — wider at the brake track than the spoke bed — is designed to manage crosswinds rather than simply fight them. Zipp calls the resulting combination of aerodynamic efficiency and lateral stability \"AeroBalance,\" and it's a philosophy baked into how the rim interacts with the air around it. The 303's shallower profile sits at a depth where handling confidence and aero benefit coexist without compromise, making it a wheel you can trust in variable conditions. Running a 650b diameter means you can fit wider tyres for additional compliance and grip, which complements that stability further.\u003c\/p\u003e\n\u003cp\u003eThe disc-brake-only design removes the rim brake track entirely, which allowed Zipp's engineers to optimise the full rim profile for aerodynamic performance rather than splitting design priorities. Paired with tubeless compatibility, you gain the option to run lower pressures for improved traction and puncture resistance — a meaningful advantage when your route isn't guaranteed to stay smooth. The ZR1 hub at the centre keeps rolling resistance low and provides the durability to back up long-haul use, whether that's a loaded gravel day or a fast road loop with unpredictable pavement.\u003c\/p\u003e\n\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eFirecrest Toroidal Rim Shape:\u003c\/strong\u003e The Firecrest profile widens toward the outer edge of the rim, which is designed to reduce aerodynamic drag and — critically — improve handling in crosswinds.

Rather than a fixed-depth rim optimized for one yaw angle and one wind condition, Zipp’s Sawtooth profile uses an undulating rim shape — depth that varies across the circumference, peaking at 40mm on the rear, tuned to manage airflow across the range of real-world riding conditions rather than a single tunnel number. The NSW designation marks this as Zipp’s top performance tier, and the 353 is the most aerodynamically sophisticated expression of what a 40mm-class road wheel can be.\u003c\/p\u003e\n\u003cp\u003eThe rim works on two levels beyond its shape. \u003cstrong\u003eHexFin ABLC\u003c\/strong\u003e — Active Boundary Layer Control — uses a pattern of hexagonal surface features that trip the aerodynamic boundary layer earlier, reducing pressure drag in the same way that dimples work on a golf ball. Hyperfoil nodes on the rim surface build on that by further directing airflow through transitions and around the wheel at varying angles. The 30mm external width supports this aerodynamic intent: wider rims create a cleaner transition to wider tires, and the 353 NSW is specifically optimized for 30mm rubber — a setup that delivers aero and rolling resistance gains that the narrow-rim era never could. The hookless carbon construction also means a 16% increase in rim impact strength compared to the previous generation.\u003c\/p\u003e\n\u003cp\u003eAt the center of the wheel is the ZR1 SL hub, running custom hybrid ceramic bearings for reduced rolling resistance and extended bearing life. With 66 engagement points, there’s minimal dead angle between pedal stroke and drive — the kind of immediate response that matters most out of corners, on short punchy climbs, or when you need to hold a wheel under pressure. The hub body is also 30g lighter than Zipp’s previous NSW hubs, a refinement that compounds with the overall weight reduction of the 353 platform.

Built directly into the wheel hardware rather than added as a separate device, it delivers real-time tire pressure monitoring to the SRAM AXS app — making the 353 NSW the first AXS-connected wheel Zipp has produced. Pressure is one of the most consequential and most overlooked variables in wheel performance: a 30mm tire running 10 psi low doesn’t just feel different, it rolls differently and handles differently. Having a live pressure read without removing a wheel or carrying a separate gauge changes how you set up and maintain your tubeless system. The hookless rim accepts 29–35mm tubeless tires at up to 73 psi, with 30mm as the intended sweet spot.\u003c\/p\u003e\n\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eSawtooth undulating rim profile\u003c\/strong\u003e — variable depth optimized for real-world yaw angles rather than a single tunnel condition, delivering more consistent aerodynamic performance across variable wind\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHexFin ABLC + Hyperfoil nodes\u003c\/strong\u003e — dual surface technologies that trip and shape the boundary layer to reduce drag, working in tandem rather than as isolated features\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated AXS Wheel Sensor\u003c\/strong\u003e — real-time tire pressure monitoring built into the wheel, no external device needed, feeds live data to the SRAM AXS app\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZR1 SL hub with 66-point engagement\u003c\/strong\u003e — ceramic bearings reduce friction and wear; 66 engagement points deliver near-immediate drivetrain response\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e25mm internal width\u003c\/strong\u003e — properly supports 29–35mm tubeless tires for correct casing shape, aerodynamic rim-to-tire transition, and optimal rolling resistance\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003eFinal Take\u003c\/h3\u003e\n\u003cp\u003eThe 353 NSW is the wheel you buy when you want Zipp’s best thinking on what a disc-brake road wheel should be — not just fast in a straight line, but genuinely capable across the conditions that make up a real ride.

The 404 Firecrest name carries real weight in the Zipp lineup — it's been the brand's benchmark all-rounder aero wheel for years, and this tubeless-disc version sits below the NSW flagship in price while keeping nearly all of its performance.\u003c\/p\u003e\n\n\u003cp\u003eAt 58mm deep, the rim splits the difference between a shallow climbing wheel and a full-depth time trial disc, which is exactly why Zipp positions it for road racing, triathlon, gran fondos, and mixed-terrain riding rather than one narrow use case. The carbon rim is hookless with a symmetrical profile, a 23mm internal width, and a 28mm max external width — proportions built around modern wider tubeless tires rather than the narrow clinchers aero wheels were originally designed around. Zipp's ABLC Sawtooth dimpling pattern runs along the rim's sidewall to smooth airflow separation at speed, which is what keeps a wheel this deep from feeling twitchy when a crosswind hits on an exposed section of road.\u003c\/p\u003e\n\n\u003cp\u003eZipp frames all of this under what it calls Total System Efficiency — the idea that four things slow a rider down: wind resistance, rolling resistance, gravity, and vibration losses, and that a wheel should be tuned against all four rather than just aerodynamics. The hookless rim design plays into that directly. Beyond the aero benefit of a smoother tire-to-rim transition, hookless construction uses resin more efficiently during layup, which Zipp says produces a lighter, stronger rim than a hooked bead of the same weight. Tire compatibility runs from 28c to 35c tubeless tires, wide enough to run lower pressures for comfort and grip on rough pavement without stepping outside the wheel's design range.\u003c\/p\u003e\n\n\u003cp\u003eThe hub is Zipp's ZR1 DB, a German-engineered design built for a quicker response and improved seal durability, with 66 points of engagement for fast pickup when you're back on the pedals out of a corner or a draft. It uses a Center Lock rotor interface, ships with 12mm thru-axle end caps, and this rear-specific build is available with either an XDR driver body or a Shimano\/SRAM HG11 body, so it isn't locked to one drivetrain brand (a Campagnolo driver body is available separately if needed).

Max tire pressure is rated to 73 psi, and the wheel carries a combined rider-and-bike weight limit of 253 lbs (115 kg).

Zipp dropped nearly 400 grams from the previous generation to arrive here, and the result is a wheel that pairs the depth riders have always wanted from the 404 with a weight that doesn't penalize you for choosing it.\u003c\/p\u003e\n\n  \u003cp\u003eThe 58mm rim depth is the defining characteristic of the 404 Firecrest, and it's not a number Zipp arrived at arbitrarily. Deep-section rims generate meaningful aerodynamic advantage at road racing speeds — the deeper the rim, the more the wheel acts like an airfoil rather than a blunt object moving through the air. At 58mm, the 404 sits in a range where that aero benefit is real and consistent on flat and rolling roads, without pushing into the handling sensitivity of 80mm-plus depths that become liabilities in crosswind conditions. The rim uses Zipp's ABLC Sawtooth dimple design — an intricate pattern across the rim surface that manages airflow boundary layers, contributing to both reduced drag and improved stability as yaw angle increases. The UD carbon fiber finish and Zipp's TSE (Total System Efficiency) manufacturing approach govern the layup geometry throughout the rim wall, with the goal of reducing wind resistance, rolling resistance, vibration losses, and weight simultaneously rather than trading one against another.\u003c\/p\u003e\n\n  \u003cp\u003eThe rim is hookless — a construction approach that Zipp uses across the Firecrest line. Hookless rims allow for more efficient resin distribution during the carbon manufacturing process, producing a rim that is lighter and stronger for a given wall thickness than a hooked equivalent. The transition between rim and tire is also more seamless aerodynamically, which reduces turbulence at the tire-rim interface at speed. The internal width is 23mm, optimized for tubeless tires in the 28-35mm range — a tire volume that supports lower pressures for improved rolling efficiency and vibration absorption while staying within the aerodynamic profile the rim was designed around. Maximum tire pressure is 73psi \/ 5.0 bar, and the wheelset requires tubeless-compatible tires. Zipp's optimized tubeless bead design allows for tool-free tire installation and removal without an air compressor. Brake interface is Centerlock disc, and the lockring ships with the wheels.\u003c\/p\u003e\n\n  \u003cp\u003eAt the center of the wheelset is the ZR1 DB hub — Zipp's German-engineered hub designed specifically for the Firecrest disc line. The ZR1 features 66 points of engagement, which translates to fast and consistent drive response when you're accelerating out of corners or onto the gas after a descent. The hub uses an improved seal design for better durability against contamination in wet and variable conditions, and runs on cartridge steel bearings. The hub shell is designed to minimize weight while maintaining the stiffness required to handle the lateral loads of road racing. The result is a hub that functions reliably under hard use without requiring frequent servicing.\u003c\/p\u003e\n\n  \u003cp\u003eThe wheelset ships with 12mm thru-axle end caps — 100mm front, 142mm rear — covering the standard disc road frame axle specifications. Driver body options are SRAM XDR and SRAM\/Shimano Road; Campagnolo compatibility is available separately. The hookless rim and tubeless-only construction are worth confirming against your current tire setup before purchasing, particularly if you're coming from a hooked rim with clincher tires. The maximum recommended system weight (rider, bike, and gear combined) is 253 lbs \/ 115 kg.\u003c\/p\u003e\n\n  \u003cp\u003eZipp backs the 404 Firecrest with a lifetime warranty for product issues while riding. At $2,150, this wheelset represents the 404's long-standing position as Zipp's most versatile aero option — deep enough to be fast on the road, light enough to be useful over varied terrain, and durable enough to hold up through training seasons and races.

At a 21.2mm rim depth and 30mm internal width, the profile stays shallow and wide, which suits XC's low-speed, technical demands better than a deeper aero rim would.

It's a legitimate way to get into Zipp's current flagship cross-country wheel without committing to the full wheelset in one purchase.\u003c\/p\u003e\n\n\u003cp\u003eZipp built the 1ZERO HITOP SW around the idea that a modern XC wheel needs to do more than just be stiff. Courses have gotten rougher, and a rim that's rigid above all else transmits every root and rock strike straight into the rider's hands. Zipp's proprietary HITOP carbon layup is tuned to flex predictably over chatter while staying stiff enough for hard efforts, and the rim carries a 30mm internal width with an asymmetrical, hookless profile rated for tires between 47 and 71c. It's built to hold up under a trail bike or full-suspension XC rig with up to 130mm of travel, which is more capability than a pure-race hardtail wheel typically offers.\u003c\/p\u003e\n\n\u003cp\u003eThe rim's \"winged\" edge profile is a deliberate design choice, not just a styling detail — the wider resting surface under the tire bead reduces the chance of a pinch flat when you clip a rock at speed, which matters more on a rough modern XC course than it did a few years ago. At a claimed 1,325 grams for the full wheelset, the 1ZERO HITOP SW stays near the top of its weight class despite that added durability margin, so you're not trading acceleration and climbing snap to get it.\u003c\/p\u003e\n\n\u003cp\u003eThis wheel also comes with Zipp's TyreWiz 2.0 tire-pressure sensor built in, giving you a real-time pressure reading instead of guessing or checking with a separate gauge before every ride. Tire pressure has an outsized effect on rolling speed and grip on an XC bike, and having that number confirmed rather than assumed is a genuine advantage during a race warm-up or a pressure-sensitive technical section. The front hub itself is Zipp's ZM2 SL, delivering 66 points of engagement for a quick, direct response when you're accelerating out of a corner, and it's available configured with either a standard axle interface or SRAM's Torque Cap system, depending on what your fork and crank setup supports.\u003c\/p\u003e\n\n\u003cp\u003eRotor mounting is Center Lock, and the wheel carries a max tire pressure rating of 50 psi with a combined rider-and-bike weight limit of 286 lbs (130 kg).

The rim runs a very shallow 21.1mm depth, a deliberate departure from the deep aero profiles Zipp built its name on, because on singletrack, absorbing terrain matters more than cutting through the air.\u003c\/p\u003e\n\u003cp\u003eThat shallow depth is tied directly to Zipp's HiTop compliance technology, a proprietary carbon layup tuned to flex in a way that passes less feedback through to the rider. Where a stiffer XC rim transmits every root and rock strike straight up through the frame, this rim is built to absorb the small, high-frequency impacts that happen too fast for a bike's suspension to fully react to. In practice, that means more traction and composure through chattery, rough sections, and a rider who can carry speed through terrain that would otherwise bounce a stiffer wheel off-line. The rim also uses what Zipp calls a winged design at the hookless bead — a broader profile that gives the tire more surface area to rest against during a hard rock strike, cutting down on the chance of a pinch flat compared to a narrower bead edge.\u003c\/p\u003e\n\u003cp\u003eThe rim carries a 30mm internal width and 37.7mm external width, an asymmetrical profile sized specifically around the 2.35 to 2.4-inch tires that dominate current cross-country racing. Zipp built the whole system around bikes running up to 130mm of suspension travel, covering everything from a rigid-feeling hardtail to a short-travel full-suspension XC race bike, which makes this wheel relevant whether a rider's chasing lap times on a smooth course or picking through a genuinely technical one.\u003c\/p\u003e\n\u003cp\u003eUnderneath, the wheel runs Zipp's ZM2 SL hubset, an aluminum hub with a six-pawl compression freewheel system that delivers 66 points of engagement — quick enough to matter when a rider needs power down the instant they're back on the pedals after a technical section. The hub uses a Center Lock rotor fixture and is available with a Microspline or XD driver body depending on the drivetrain. Twenty-four Sapim CX-Ray steel spokes lace the rim to the hub on both front and rear, a spoke count and pattern built for a balance of low weight and the stiffness a race wheel still needs at the hub-to-rim interface.\u003c\/p\u003e\n\u003cp\u003eZipp also builds the 1ZERO HiTop SW around its TyreWiz 2.0 system, a valve-integrated pressure sensor that gives a rider real-time tire pressure data instead of a guess from a squeeze test before the start line. On an XC wheel this tuned to a specific tire width and travel range, knowing exact pressure matters more than it does on a general-purpose trail wheel, and it's the kind of detail that separates this wheel from a simpler carbon hoop. As a complete pair, the 1ZERO HiTop SW wheelset is built light — Zipp lists it around 1,325 grams claimed — while still carrying a 130kg system weight rating, so it's built for racing without asking a rider to baby it on rough terrain.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Zipp","offers":[{"title":"Black \/ Microspline","offer_id":43522093875244,"sku":"00.1918.720.002","price":1075.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ XD Driver","offer_id":43522093908012,"sku":"00.1918.720.000","price":1075.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/zipp-1zero-hitop-sw-disc-brake-centerlock-29-wheel-rear-5624076.jpg?v=1771295948"},{"product_id":"zipp-1zero-hitop-sw-disc-brake-centerlock-29-wheel-sid-blue-graphic-rear","title":"Zipp 1ZERO HITOP SW Disc Brake Centerlock 29\" Wheel SID Blue Graphic - Rear","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003eZipp 1ZERO HITOP SW Disc Brake Centerlock 29\" Wheel SID Blue Graphic - Rear\u003c\/strong\u003e is Zipp's first cross-country-specific wheelset in nearly 30 years, and the gap shows in how differently the company approached it compared to a typical XC wheel. The rim uses Zipp's proprietary HiTop carbon layup in a hookless, asymmetrical, winged profile — 21.2mm deep, 30mm internal width, 37.7mm maximum external width — built in UD carbon. The winged shape gives the tire a smoother resting surface against the rim, which reduces the odds of a pinch flat when you clip a rock or root at speed rather than just adding material to make the rim stiffer everywhere.\u003c\/p\u003e\n\u003cp\u003eThat distinction is the whole point of the HiTop design. Zipp's engineering team, led by design engineer Aaron Packard and test engineer Brian Leathers, built this wheel on the idea that maximum stiffness isn't actually what makes an XC wheel fast anymore — as Zipp puts it, a wheelset should feel alive rather than just being stiff above all else. The rim is engineered to comply with rough terrain instead of transmitting every hit straight into the rider, while still holding the stiffness needed for efficient climbing and hard accelerations out of corners. The project carried over momentum from Zipp's 3ZERO MOTO enduro wheelset, adapting that same terrain-compliant approach to the lighter, faster demands of cross-country racing.\u003c\/p\u003e\n\u003cp\u003eAt the hub, this rear wheel runs Zipp's ZM2 SL hubset with 66 points of engagement, available with an XD or Microspline driver body to match SRAM or Shimano drivetrains. In its lightest configuration, the 1ZERO HITOP SW comes in at roughly 1,375 grams, and it integrates with Zipp's TyreWiz 2.0 system for real-time tire pressure monitoring — useful on a wheel built around running tubeless tires at precise, often lower pressures than riders default to. It's rated for tubeless tires in the 47-71c range, roughly 1.85 to 2.8 inches, with a 50 psi maximum pressure and a 286-pound system weight limit, and Zipp built it to handle bikes with up to 130mm of suspension travel — squarely in cross-country and light trail territory rather than anything built for aggressive descending.\u003c\/p\u003e\n\u003cp\u003eThe SID Blue graphic on this wheel isn't an arbitrary color choice. It matches the Blue Crush signature colorway RockShox uses on its SID Ultimate fork, and since Zipp and RockShox are both part of SRAM's component family, the pairing lets a rider building a dedicated XC race bike match their wheels to their fork rather than mixing graphics from unrelated brands. It's a small detail, but it reflects how tightly SRAM coordinates its component lines when a rider is building a bike around one ecosystem.\u003c\/p\u003e\n\u003cp\u003eWhat all of this adds up to on the trail is a wheel built for riders who need speed to survive contact with actual terrain, not just a number on a stiffness chart. Cross-country racing has moved toward rougher, more technical courses over the past several years, and a wheel that flexes intelligently over roots and rock gardens while still transferring power efficiently on the climbs is a direct response to that shift. For a racer building a dedicated XC bike, or a rider who wants a lightweight 29er wheel that can carry speed through rough sections rather than getting knocked off line by them, the 1ZERO HITOP SW is Zipp applying its carbon engineering experience to a category it hadn't touched in decades — and building something purpose-specific rather than a road wheel philosophy adapted to dirt.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Zipp","offers":[{"title":"Black \/ SID Blue Graphic \/ XD Driver","offer_id":43522094039084,"sku":"00.1918.720.001","price":1075.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/zipp-1zero-hitop-sw-disc-brake-centerlock-29-wheel-sid-blue-graphic-rear-5574703.jpg?v=1771295948"},{"product_id":"zipp-1zero-hitop-s-disc-brake-6-bolt-29-wheel-front","title":"Zipp 1ZERO HITOP S Disc Brake 6-Bolt 29\" Wheel - Front","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003eZipp 1ZERO HITOP S Disc Brake 6-Bolt 29\" Wheel - Front\u003c\/strong\u003e is the front half of Zipp's cross-country wheel platform, sold individually for riders building a custom wheelset or replacing a single wheel rather than the full pair.

Modern cross-country courses have gotten rougher, and a rim that's simply stiff everywhere tends to bounce off roots and rock gardens instead of tracking through them. The HITOP layup is built to absorb some of that hit at the rim itself, which shows up as more confidence on the rough sections of a course rather than a smoother ride in isolation.

That flare adds support right where a tire is most likely to pinch against the rim on a hard hit, reducing the chance of a pinch flat without adding a hooked bead's weight or complexity. It's finished in unidirectional carbon fiber with adhesive decals rather than a painted graphic, keeping weight down where it doesn't need to be added back.

It’s a wind tunnel tuned, dimpled  carbon-fiber hoop that is stronger than most aluminum rims. Zipp took the  technology that they used to build wheels to withstand Paris-Roubaix and  applied the thinking to clincher rims, which need to be even stronger thanks to  the unsupported sidewalls. It’s the same rim as their rim-brake 202, as the  strength needed works not only to support the rim from side pressure, but from  vertical impact and the tube and tire pushing outwards.\u003c\/p\u003e\n\u003cp\u003eThe 202  is the climbing shape, which means it’s the lightest clincher in the Zipp  stable, great for not only moving uphill, but accelerating quickly, and  grinding away at slow speeds.

The Firecrest shape was conceived to  give the rider greater stability by minimizing the side loads that can create  steering torque in crosswinds. The 202 itself is more stable in a crosswind  than a conventional box-section clincher, which is a pretty cool feat.

The Firecrest 303 rim is a natural for disc-brake applications. The rim hits the sweet spot of strong, light, and aero. The rear wheel comes in at just 885 grams. The rim possesses Zipp’s Firecrest shape. It is 45mm deep and 26.4mm wide at the brake track but 28.5mm a bit below. Its wide shape also decreases rolling resistance, improves grip, and even gives you more of an air cushion over rough roads. The width adds comfort and reduces rolling resistance by increasing air volume inside the tire. It is not only a bigger cushion, but at a given tire width and pressure, deformation over bumps and surface imperfections happens more easily. The Clincher rim is the same one found on the rim-brake version. This allowed Zipp to maintain their ideal weight to stiffness ratio that they found with the original model. \u003c\/p\u003e \n\u003cp\u003eZipp employs their 177D hub, which was purpose-built for disc brake riding.

At 58mm deep, it sits in the sweet spot between a shallow climbing wheel and a full-depth time trial disc, making it equally at home in a road race, a triathlon, or a long gran fondo over mixed terrain. This is the wheel Zipp points to when a rider wants one aero front wheel that doesn't force a tradeoff between racing speed and all-day comfort.\u003c\/p\u003e\n\u003cp\u003eThe rim itself is full carbon and hookless, meaning the sidewall transitions straight into the tire bead rather than curling over it. Zipp uses this construction because it allows for more efficient resin distribution during layup, producing a rim that's lighter and stronger while creating a more seamless, aerodynamic junction between tire and rim. The 23mm internal width is built around wider tubeless tires run at lower pressure, specifically 28-35c tubeless tires compatible with tube or sealant setups, with a maximum outside width of 28mm and a max tire pressure of 73psi. Running wider tires at reduced pressure is central to how Zipp approaches speed on real roads, not just in a wind tunnel.\u003c\/p\u003e\n\u003cp\u003eThat approach has a name: Zipp calls it Total System Efficiency, or TSE, developed by engineers at the brand's Nest Advanced Development Lab in Indianapolis. Instead of chasing aero numbers alone, TSE treats wind resistance, rolling resistance, gravity, and vibration loss as one connected system, and the 404 Firecrest reflects that thinking throughout. The rim surface uses Zipp's ABLC Sawtooth Technology, a dimpled pattern that manages airflow across the rim's surface to hold stability in crosswinds without adding drag. It's a wheel built to stay composed at speed on the kind of variable, gusty roads riders actually train and race on, not just in ideal conditions.\u003c\/p\u003e\n\u003cp\u003eAt the center of the wheel is Zipp's new ZR1 DB hub, engineered in Germany with an improved seal design aimed at both durability and quicker engagement, delivering 66 points of engagement so power gets to the road faster when you put in an effort. The hub uses steel cartridge bearings and a Center Lock disc brake mount, and is built to handle a max recommended system weight of 253 pounds. As a full wheelset, Zipp lists this build at 1,559 grams in its lightest configuration, a meaningful drop from earlier generations of the 404 without sacrificing the stiffness or stability that made the line a staple in the first place. For riders who want a versatile aero front wheel that performs on race day and holds up through a full season of training, the 404 Firecrest remains one of the more proven choices in Zipp's lineup.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Zipp","offers":[{"title":"Default Title","offer_id":43704835604524,"sku":"00.1918.620.000","price":1050.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/zipp-404-firecrest-tubeless-disc-front-wheel-4496946.jpg?v=1771295894"},{"product_id":"zipp-858-nsw-disc-clincher-rear-wheel","title":"Zipp 858 NSW Disc Clincher Rear Wheel","description":"\u003cp\u003eThe Zipp 858 NSW Clincher Wheel is the latest step in  speed.  The wheel takes advantage of  Zipp’s Hyperfoil technology to create a wheel that’s deep in a headwind, but  much shallower in a crosswind.  And  thanks to the increasing popularity of disc brakes, it is offered in two  distinct versions, the rim brake model and the disc brake model.  This is a wheel for riding the flats, mastering  time trials, and killing the bike leg in multi-sport events.  Zipp triathletes say it’s versatile enough to  be your single race wheelset.\u003c\/p\u003e\n\u003cp\u003eYou’ll notice the waves in the rim shape.  Those are Hyperfoil nodes.  The rear wheels have 24 nodes, while the  front rim brake has 18 and the front disc brake 24.  The nodes are clocked with the spokes to make  them work better.  The nodes are inspired  by the way whales move through water, and achieve something Zipp likes to call  AeroBalance.  That’s their way of saying  that the wheel is fast but stable.   They’ve found that the wheel is as stable in crosswinds as their 404,  but faster than their 808.  Cool trick.  The deepest parts of the rim are 82mm like  the 808, but are combined with sections as shallow as 77mm.  When you add on the Sawtooth dimple pattern  and HexFin dimples, it’s faster still.\u003c\/p\u003e\n\u003cp\u003eThe Carbon Clincher Rim Brake version has Zipp’s ShowStopper  brake treatment, which improves both wet and dry braking, particulary the  dry.  It has 18 front spokes, 24  rear.  The set weighs 1750g, 808g for the  front, 942g for the rear.  The rim width  goes up to 24.4mm on the outside in front 23.7mm max width rear, and has a 17mm  internal width.  \u003c\/p\u003e\n\u003cp\u003eThe Carbon Clincher Disc Brake version is a bit different  owing to the needs of rotor disc brakes.   The front and rear rims are identical.   They’re 24-spokes, front and rear, with the same 24-spoke 23.7mm wide,  17mm internal width rim.  The HexFin  dimple pattern is extended to the end of the rim to further aerodynamics  because you don’t need a brake track.\u003c\/p\u003e\n\u003cp\u003eZipp loves Sapim CX-Ray spokes.  They’re light, fast, strong.  The rim brake version uses straight-pull  spokes while the disc brake version uses J-bend.  The different forces on the wheel dist\u003c\/p\u003e\n\u003cp\u003eBoth wheel sets feature Zipp’s Cognition hubs.  The rim brake version utilizes a flangeless  front hub and a minimal, flanged rear hub that features two-cross spoking on  both sides.  A similar-looking scalloped,  flanged design is employed both front and rear on the disc brake version.  It is a bit different, as Zipp found that  J-bend spokes are better for disc wheels, and, as such, the flanges are  designed to be as light as possible without sacrificing strength.  The disc brake version hubs are designed for  Centerlock splined rotors only.  The disc  brake hubs come with quick release skewers and hand-removable end caps that can  convert the wheel from quick-release to 100x12mm, 100x15mm thru axles in front,  and 142x12mm thru-axles in the rear.    \u003c\/p\u003e\n\u003cp\u003eAs should be expected, you can choose between a  Campagnolo-compatible 9\/10\/11-speed cassette body, and a Shimano\/SRAM body.

Zipp was founded in 1988 by motorsports engineer Leigh Sargent, and released the Zipp 3000 — the first three-spoke carbon wheel — the following year. That racing-first background still shows up in how Zipp engineers a wheel like the 404 NSW: not as a lightweight accessory, but as an aerodynamic tool built to a specific job. The rim runs a 58mm depth with a symmetrical carbon profile, hooked, at a 19mm internal width and 27mm max external width — proportions built around modern tubeless road tires rather than retrofitted to fit them.\u003c\/p\u003e\n\u003cp\u003eThe signature feature on the rim surface is Zipp's ABLC Sawtooth dimpling, a pattern of nodes across the rim's sidewall that functions on the same principle as the dimples on a golf ball. Air flowing over a smooth deep-section rim tends to separate from the surface at a certain point, creating a turbulent, energy-sapping wake behind the wheel. The Sawtooth dimples disrupt that airflow deliberately, at a frequency Zipp tuned to around 20 mph, generating smaller, more predictable vortices instead of one large unstable one. In practice, that shows up as a wheel that holds its line better in gusting crosswinds than a smooth-sided deep-section rim of the same depth — you spend less energy correcting your line and more energy actually moving forward.\u003c\/p\u003e\n\u003cp\u003eThe hub is Zipp's Cognition design, running on stainless steel cartridge bearings with a Center Lock disc interface, and this rear wheel is built with an XDR driver body, compatible with SRAM and Shimano 11-speed drivetrains. Rim construction uses UD carbon fiber finished with Zipp's Impress process. In its lightest configuration — 12mm thru-axle, XDR driver body — this rear wheel comes in at roughly 900 grams, part of a claimed 1,690-gram set weight when paired with the matching front wheel. It's tubeless-ready and rated to 125 psi maximum tire pressure, with a 250-lb system weight limit, and Zipp built it around 25mm-and-wider tubeless tires rather than the narrower clinchers deep-section wheels were originally designed around.\u003c\/p\u003e\n\u003cp\u003eAll of that adds up to a wheel built for exactly one job: holding speed on the road with as little compromise as possible. The 58mm depth is deep enough to make a real aerodynamic difference at race pace without pushing into the territory where a rim becomes hard to control in a crosswind, and the tubeless setup lets you run lower pressure for grip and comfort on rough pavement without giving up the low rolling resistance a deep carbon rim is built around. Zipp's motorsports-engineering roots and its decades of testing carbon wheels under professional racers, including Mark Allen's Ironman-winning rides on Zipp wheels as early as 1990, are the reason a wheel like this exists at all — building a rim shape that manages airflow instead of just cutting through it took real aerodynamic research, not a marketing department's guess.\u003c\/p\u003e\n\u003cp\u003eThis is a race wheel for riders who've already decided speed and stability at speed matter more than shaving the last few grams off a climbing wheel.

The \u003cstrong\u003eZipp 858 NSW Tubeless Disc Rear Wheel\u003c\/strong\u003e was engineered to break that tradeoff. With an undulating 82–85mm Sawtooth rim profile, Hyperfoil nodes, and HexFin ABLC dimple geometry, the 858 NSW simultaneously reduces aerodynamic drag and side force — a combination that conventional deep-section wheels, smooth and constant-depth, can't achieve. This is Zipp's highest-performing aero wheel, designed for riders who demand maximum speed at the deepest end of the rim-depth spectrum.\u003c\/p\u003e\n\u003cp\u003eThe aerodynamic system starts with the Sawtooth profile — Zipp's patented variable-depth rim shape that gives the 858 NSW its distinctive scalloped appearance. Along the inner diameter of the rim, a series of Hyperfoil nodes (fin-shaped structures integrated into the Sawtooth geometry) work in concert with HexFin ABLC dimples to control airflow around the wheel. The HexFin ABLC dimples are hexagonally shaped depressions arranged in fin-shaped clusters at each Hyperfoil. Their angular geometry increases boundary layer mixing, keeping airflow attached to the rim surface longer and reducing drag. Meanwhile, the Sawtooth undulations increase vortex shedding frequency — producing more, smaller, and more predictable vortices. The practical result is a wheel that holds a line in gusting crosswinds with significantly less rider input than a conventional constant-depth rim at the same depth. Zipp calls this AeroBalance: peak aerodynamic efficiency and genuine crosswind stability in the same wheel.\u003c\/p\u003e\n\u003cp\u003eThe 858 NSW is built on Zipp's TSE (Total System Efficiency) framework, which targets the four barriers to cycling speed — wind resistance, gravity, rolling resistance, and vibration losses — as an interconnected system. The hookless carbon rim construction addresses multiple barriers at once. Hookless rims are lighter than hooked alternatives and create a more seamless interface with tubeless tires, enabling lower pressures where tubeless compounds perform best. The 23mm internal rim width is optimized for 28–32mm tires, with Zipp citing 30mm as the aerodynamic and compliance sweet spot on this rim. Running a 30mm tubeless tire at lower pressure reduces rolling resistance, absorbs road vibration, and keeps the contact patch stable through corners — gains that accumulate meaningfully over a long race or triathlon run leg. Maximum recommended pressure is 73psi, keeping you in the range where the tire and rim combination works as designed.\u003c\/p\u003e\n\u003cp\u003eThe ZR1 SL hub runs custom hybrid ceramic bearings — ceramic rolling elements in steel races — for reduced friction and extended service life compared to full-steel alternatives. The center lock disc interface ships with the lockring included. Driver body options cover SRAM XDR for current 12-speed drivetrains and SRAM\/Shimano Road (HG11) for 11-speed, making the 858 NSW compatible across the range of modern groupsets. Zipp's ImPress direct-print graphics apply branding without covering the HexFin ABLC dimples — a deliberate choice, since exposed dimples are required for the aerodynamic system to function.

That weight reduction comes from Zipp's Carbon Internal Reinforcement (CiR) process, which produces a rim 10% lighter while maintaining equivalent structural strength. The 858 NSW is built around Zipp's Total System Efficiency (TSE) framework, which treats wheel performance as four separate problems to solve simultaneously: wind resistance, gravity, rolling resistance, and vibration losses. Addressing all four at once, rather than optimizing aerodynamics while accepting tradeoffs elsewhere, is the engineering premise behind the wheelset.\u003c\/p\u003e\n\n  \u003cp\u003eThe most technically significant element is the Sawtooth profile — Zipp's patented rim shape that varies between 82mm and 85mm in depth around the circumference. Developed through wind tunnel testing, CFD analysis, and real-world riding, and informed by the principles of biomimicry, the Sawtooth uses a series of fin-shaped Hyperfoil nodes along the inner diameter of the rim to manage airflow at each undulation. Each Hyperfoil node carries HexFin ABLC dimples: hexagonally shaped depressions arranged in variable-sized clusters that increase boundary layer mixing and keep airflow attached to the rim surface. The combined effect is that the 858 NSW simultaneously reduces aerodynamic drag and side force at wind yaw angles. Most deep-rim wheels make a tradeoff between those two — a rim optimized purely for drag reduction tends to behave like a sail in crosswinds. The Sawtooth addresses both. At higher yaw angles, where a conventional 85mm rim starts pushing the front wheel off line, the Hyperfoil nodes increase vortex-shedding frequency: more frequent, smaller, more predictable vortices rather than fewer large ones that create erratic handling. The result is an 85mm wheel that holds a line in crosswind conditions with confidence that its depth alone wouldn't suggest.\u003c\/p\u003e\n\n  \u003cp\u003eAt the center of the wheelset is the Cognition V2 hub, built around Zipp's Axial Clutch V2 mechanism. The Axial Clutch decouples the engagement mechanism from the freehub body when you're not under load, reducing rotational drag while coasting. In triathlon and time trial contexts — long descents, technical corners, transition zones — that reduction in passive friction accumulates over the course of a race. The V2 revision improves engagement timing and durability over the original Cognition design. Bearings are cartridge stainless steel. Graphics are applied using Zipp's ImPress direct-print technology, which prints directly onto the carbon surface rather than using decals, allowing the HexFin dimples to function without surface interruption.\u003c\/p\u003e\n\n  \u003cp\u003eThe hookless rim pairs with a 23mm internal width and an optimized tire bed designed for consistent tubeless mounting. Maximum recommended tire pressure is 73psi (5.0 bar). Zipp identifies 28mm as the optimal tire width for the 858 NSW — the point where aerodynamic efficiency and rolling resistance combine most favorably. Minimum usable tire width is 25mm. The 858 NSW is designed for tubeless tires; running a tube with a tubeless-ready tire is supported but not the primary use case. Brakes use a Center Lock rotor interface, with a lockring included. The wheelset ships with 12mm through-axle end caps front and rear. Driver body compatibility covers XDR (SRAM 12-speed) and HG11 (Shimano and SRAM 11-speed); a Campagnolo N3W body is sold separately. Maximum recommended system weight is 250lbs (114kg).

The tubeless-only requirement is a real constraint — verify tire compatibility before committing to a build, as not all tubeless tires are cleared for hookless rims. At $4,600, the 858 NSW is the top of Zipp's wheel lineup, and the engineering depth behind the rim profile, the hub, and the construction method reflects that position.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Zipp","offers":[{"title":"Black \/ XDR Driver","offer_id":43522158821420,"sku":"00.1918.698.001.WS","price":4600.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ HG11 (Shimano \/ SRAM 11s)","offer_id":44160758153260,"sku":"00.1918.698.000.WS","price":4600.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/zipp-858-nsw-carbon-disc-brake-tubeless-wheelset-8805218.jpg?v=1771295893"},{"product_id":"zipp-cognition-freehub-kit-v2-nsw-1","title":"Zipp Cognition Freehub Kit V2 NSW","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003eZipp Cognition Freehub Kit V2 NSW\u003c\/strong\u003e is a direct replacement freehub body for Zipp NSW wheels equipped with the Cognition hub system.

This is the wheel you bolt on when aerodynamics are the priority, and the Firecrest rim shape is the reason it works. Rather than a simple deep-V profile, the Firecrest design uses a wider, more rounded cross-section that manages airflow across a range of wind angles, keeping the wheel stable and predictable when conditions get gusty.

The 23mm internal width with a hookless rim bed is optimized for modern tubeless tires in the 28-32mm range, with 28mm being the sweet spot. Wider tires on a wide internal rim create a smoother, more aerodynamic tire profile that reduces rolling resistance and improves grip — a measurable gain you feel over the course of a long ride or a 40K time trial. The ABLC dimple pattern across the rim surface is Zipp's approach to boundary layer control, using precisely placed dimples to manage how air separates from the rim and reduce overall drag.\u003c\/p\u003e\n\u003cp\u003eAt the heart of the 808 Firecrest sits Zipp's German-engineered ZR1 disc brake hub.

Cartridge steel bearings keep the hub running smoothly and are straightforward to service. The center-lock disc brake interface pairs with a 12mm thru-axle for stiff, consistent braking under hard efforts. Sapim CX Sprint spokes — a proven J-bend design — handle the load reliably, and the symmetrical rim profile keeps spoke tension balanced for a truer, more durable wheel over time. Freehub compatibility covers SRAM XDR and Shimano\/SRAM HG11 out of the box, with a Campagnolo N3W driver body available separately.\u003c\/p\u003e\n\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll-Out Aerodynamic Performance:\u003c\/strong\u003e The 80mm Firecrest rim profile is Zipp's deepest offering, shaped to reduce drag across a wide range of wind angles rather than just in a straight headwind.

At 80mm deep, these wheels cut through the air with the kind of efficiency that makes a measurable difference over a long flat stage or a sustained time trial effort — yet Zipp's engineering approach means they're not a one-trick pony reserved for dead-calm days. The Firecrest rim profile and ABLC Sawtooth dimple pattern work together to manage crosswind stability, so you spend less energy fighting the wheel and more energy moving forward.\u003c\/p\u003e\n\u003cp\u003eTubeless compatibility is central to how the 808 Firecrest is designed to perform. The hookless carbon rim is optimized for 28mm tires run at lower pressures — a setup that reduces rolling resistance, absorbs road vibration, and gives you more confident cornering grip than a traditional clincher arrangement at high pressure. Less rolling resistance, fewer flats, and a more compliant ride aren't side effects here; they're part of the design intent. Zipp refers to this holistic approach as Total System Efficiency, where rim shape, tire interface, and hub performance are engineered to work as a single system rather than independent components bolted together.\u003c\/p\u003e\n\u003cp\u003eThe disc-brake format frees the rim from braking duties entirely, which means the carbon layup and rim geometry are optimized purely for speed and stiffness. The ZR1 DB hub keeps things quiet and dependable, offering the kind of smooth engagement that disappears into the background on long rides and reappears as sharp responsiveness when you need to accelerate out of a corner or respond to a surge in a group.

The Firecrest rim shape and \u003cstrong\u003eABLC Sawtooth dimple pattern\u003c\/strong\u003e are designed to smooth airflow around the rim at a range of yaw angles, reducing the destabilizing effect of crosswinds and keeping the wheel predictable when the air isn't perfectly still.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHookless Tubeless for Lower Rolling Resistance:\u003c\/strong\u003e The hookless rim bed is engineered specifically to work with tubeless tires at the widths and pressures where rolling resistance is lowest. Running a 28mm tubeless tire at a controlled lower pressure allows the tire to deform slightly over road imperfections rather than bouncing off them — a dynamic that reduces energy loss and increases the contact patch's ability to grip the road through corners. It's a setup that rewards riders who dial in tire pressure carefully.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc-Brake Optimization:\u003c\/strong\u003e Removing braking loads from the rim is one of the more significant structural advantages of a disc-brake-specific carbon wheel. Because the 808 Firecrest disc never sees braking heat or lateral braking forces at the rim, Zipp's engineers can focus the carbon layup entirely on stiffness, aerodynamic shape, and weight. The result is a rim that doesn't need to make compromises between braking durability and ride performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZR1 DB Hub Durability and Engagement:\u003c\/strong\u003e The ZR1 DB hub is Zipp's purpose-built disc hub platform, designed to deliver consistent, smooth engagement across varied riding conditions.

Where deeper-section wheels prioritize maximum drag reduction in controlled conditions, the \u003cstrong\u003eZipp 454 NSW Tubeless Disc Front Wheel\u003c\/strong\u003e is built around what Zipp calls AeroBalance — the simultaneous reduction of both aerodynamic drag and lateral side force across all wind angles. The practical result is a wheel that's fast in a straight line and predictable when the wind arrives at an angle, which in real riding is almost always. This is Zipp's engineering answer to the problem that deep, constant-depth aero rims create: speed purchased at the cost of crosswind handling confidence.\u003c\/p\u003e\n\n  \u003cp\u003eThe defining engineering is the Sawtooth rim shape, a patented variable-depth profile that undulates between 53mm and 58mm around the circumference. This variation isn't a cosmetic detail. Conventional aero rims operating at a constant depth produce large, powerful vortices as air passes over the rim profile — vortices that generate unpredictable side forces in gusting or angled wind. Zipp's wind tunnel and CFD development found that varying the rim depth creates Hyperfoil nodes: the raised, fin-shaped structures distributed around the rim's inner diameter that work in concert with the HexFin ABLC dimples to increase vortex shedding frequency. Higher frequency means more vortices per unit of time, but each one is smaller and less powerful, and together they're more predictable. The practical translation: the rider expends less energy holding a line in crosswind conditions. The HexFin ABLC dimples are hexagonal depressions at each Hyperfoil, arranged in fin-shaped clusters of variable sizes. Their angular geometry increases boundary layer mixing — keeping airflow attached to the rim surface longer — for reduced drag and improved handling in side winds. Zipp applies the wheel graphics using ImPress, a direct-print process, precisely because conventional paint fill would compromise the dimple geometry that the aerodynamic system depends on.\u003c\/p\u003e\n\n  \u003cp\u003eThe rim itself is hookless carbon, finished in UD fiber. Removing the bead hook from the rim wall allows for more efficient resin distribution in the carbon layup — a lighter and structurally stronger construction compared to a hooked rim of equivalent dimensions. The transition between tire bead and rim at the hookless interface is also more aerodynamically seamless than a traditional hooked profile, contributing to the wheel's overall drag reduction. The rim measures 23mm internally, sized for 28–35c tubeless tires — Zipp recommends 28mm as the optimal pairing for the best combined aerodynamic and rolling resistance performance on this wheel. Maximum tire pressure is 73 PSI \/ 5.0 bar. The disc brake interface is Center Lock with the lockring included. Maximum system weight is 253 lbs \/ 115 kg.\u003c\/p\u003e\n\n  \u003cp\u003eThe ZR1 SL front hub uses custom hybrid ceramic bearings and delivers 66 points of engagement. For a front wheel, hub engagement translates to how immediately the wheel responds to rider input coming out of corners and through direction changes. The ZR1 SL is 30 grams lighter than the predecessor NSW hub, part of an overall weight reduction in this generation of the 454 NSW — the full pair weighs 1,400 grams.\u003c\/p\u003e\n\n  \u003cp\u003eZipp's Total System Efficiency (TSE) framework is the organizing logic behind how these elements interact. TSE identifies four performance losses a road cyclist contends with — wind resistance, rolling resistance, gravity (weight and durability), and vibration losses — and addresses all of them rather than trading one against another. Hookless tubeless construction reduces rolling resistance and vibration transmission. The Sawtooth rim reduces wind resistance while improving crosswind stability. The ZR1 SL hub saves rotational weight. The 454 NSW front wheel is a $2,000 commitment.

Zipp positions the 858 NSW as the wheel of choice for triathlon, time trialing, and road applications where raw velocity is the primary objective. It is not a versatile all-rounder; it is a purpose-built speed tool. At 719 grams, the front wheel is also significantly lighter than the previous 858 NSW generation — Zipp removed more than 243 grams from the overall wheelset during the redesign. That reduction shows up in acceleration and sustained-effort efficiency, and it means the 858 NSW delivers the aerodynamic return of an 85mm rim at a weight typically associated with rims that are 20mm shallower.\u003c\/p\u003e\n\n  \u003cp\u003eThe central technology in the 858 NSW is Zipp's Sawtooth rim profile — a patented variable-depth design developed through wind tunnel testing, CFD modeling, and real-world validation. The rim doesn't maintain a constant 85mm depth; it undulates between 82mm and 85mm, with a series of raised Hyperfoil nodes spaced along the inner rim diameter. Each of these nodes is paired with HexFin ABLC dimples — hexagonally shaped depressions whose angular geometry increases boundary layer mixing at the rim surface, helping keep airflow attached for reduced drag and improved crosswind stability. The dimples are arranged in fin-shaped clusters of variable sizes that work with each Hyperfoil to manage vortex shedding. The result is what Zipp calls AeroBalance: the Sawtooth profile simultaneously reduces both aerodynamic drag and side force across all wind yaw angles. That's the key distinction — most deep rims trade crosswind handling for aero efficiency, generating rim-induced steering torque that the rider has to counteract. The 858 NSW is engineered to reduce both variables at once.\u003c\/p\u003e\n\n  \u003cp\u003eZipp's TSE (Total System Efficiency) framework governs how every element of the 858 NSW was designed. The approach addresses the four barriers to cycling speed — wind resistance, rolling resistance, gravity (weight and structural durability), and vibration losses — rather than optimizing a single metric. The Sawtooth profile handles wind. The hookless tubeless rim addresses rolling resistance and weight together: eliminating the bead hook creates a more precise tire interface that reduces rolling resistance, and the hookless construction itself removes material from the rim. The Carbon Internal Reinforcement (CiR) layup achieves the same structural integrity as the previous generation at 10% less weight. Zipp's data identifies 28mm as the optimal tire width for the 858 NSW — wide enough to run lower pressures for decreased rolling resistance without generating excess frontal area. Minimum tire width is 25mm, and maximum tire pressure is 73psi\/5.0 bar.\u003c\/p\u003e\n\n  \u003cp\u003eThe Cognition V2 hub at the center of the 858 NSW is built around Zipp's Axial Clutch V2 mechanism. Conventional hub designs create drag through the engagement mechanism even when the rider isn't pedaling — the clutch system is in constant light contact with the driver body during coasting. The Axial Clutch V2 separates the engagement mechanism from the bearing load path when not under pedaling load, reducing friction during descents and transitions where maintaining speed without effort matters most. The result is a hub that rolls efficiently pedaling or coasting, with quicker engagement when power is reapplied. The ImPress graphics process, which prints designs directly onto the carbon fiber rather than applying decals, is directly related to aerodynamic performance — a smooth surface at each HexFin dimple location allows the dimples to manage vortex shedding as designed, without a decal layer interrupting their geometry.\u003c\/p\u003e\n\n  \u003cp\u003eThe front wheel uses a 23mm internal width rim with a maximum outside width of 27mm. Hub spacing is 12mm thru-axle with end caps included; the brake interface is Center Lock disc with lockring included. The hookless design is optimized for tubeless tires — Zipp publishes a compatibility guide that should be confirmed before tire selection, as not every tubeless-ready tire is approved for hookless bead seats. Running a tubeless-ready tire with a tube is possible as a backup option. The 858 NSW is sold as an individual wheel, allowing riders to pair it with the 858 NSW rear or mix wheel depths for specific conditions or race formats.

The \u003cstrong\u003eZipp 808 Firecrest Carbon Disc-Brake Tubeless Front Wheel\u003c\/strong\u003e is Zipp's most aggressive road wheel offering, built for riders who want to translate every watt into forward motion without anything left on the table. At 752g for the front wheel (lightest configuration, 12mm thru-axle, no tape or valves), it carries that 80mm depth without punishing you on the scale.\u003c\/p\u003e\n\u003cp\u003eThe 808 is the wheel Zipp designed for triathlon transitions, flat-stage criteriums, and time trial courses where the terrain stays low and the wind is the primary variable. The current disc-brake version is engineered for thru-axle frames, with 12mm end caps included and a center lock rotor interface. The ZR1 DB hub — German-engineered, with 66 points of engagement — provides instant power transfer and is compatible with Shimano HG, SRAM XDR, and Campagnolo N3W driver bodies. Zipp builds the 808 front alongside the Super-9 Disc rear as the preferred TT and triathlon pairing, though for road racing, a double 808 setup remains the most committed aero configuration in their lineup.\u003c\/p\u003e\n\u003cp\u003eTwo design technologies give the 808 its aerodynamic character. The Firecrest rim profile — Zipp's wide, toroidal rim shape — is designed to treat the rim and tire as a unified aerodynamic surface rather than two separate parts. By broadening the rim bed to match wider tire widths, Firecrest creates a continuous fairing between tire shoulder and rim wall that reduces turbulence at the transition zone. The ABLC (Aerodynamic Boundary Layer Control) dimple pattern builds on this: a complex arrangement of dimples engineered into the carbon surface that manages the boundary layer of airflow around the rim as yaw angle increases. Most riding happens with wind coming from angles other than straight ahead, and the ABLC pattern is specifically designed to delay airflow separation — and the drag penalty that comes with it — across that real-world range of conditions. Zipp calls their overarching approach TSE (Total System Efficiency), the philosophy that the rim, tire, and frame should be treated as one integrated system.\u003c\/p\u003e\n\u003cp\u003eThe 808's 23mm internal-width hookless construction is tubeless-only — no clincher tires, no inner tubes. The recommended tire width is 28mm, with a minimum of 25mm, and the maximum pressure is 73 psi \/ 5.0 bar. That pressure ceiling is by design: at 25–28mm widths and lower pressures, rolling resistance drops and road noise dampens, while the rim's aero profile continues to function efficiently at speed.

Available in three diameters — 25.4mm, 27.2mm, and 31.6mm — it covers a wide range of frame specifications, from older road standards to contemporary builds.\u003c\/p\u003e\n\n\u003ch3\u003eZipp Service Course SL Seatpost Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Carbon fiber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSetback:\u003c\/strong\u003e 20mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamp:\u003c\/strong\u003e Two-bolt saddle clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter options:\u003c\/strong\u003e 25.4mm, 27.2mm, 31.6mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Zipp","offers":[{"title":"Black \/ 25.4mm","offer_id":43522240774188,"sku":"00.6818.056.001","price":190.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ 27.2mm","offer_id":43522240839724,"sku":"00.6818.056.002","price":190.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ 31.6mm","offer_id":43522240872492,"sku":"00.6818.056.000","price":190.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/zipp-service-course-sl-seatpost-20mm-setback-7772749.jpg?v=1771295892"},{"product_id":"zipp-service-course-sl-seatpost-0mm-setback","title":"Zipp Service Course SL Seatpost - 0mm Setback","description":"\u003cdiv\u003e\n  \u003cp\u003eThe \u003cstrong\u003eZipp Service Course SL Seatpost — 0mm Setback\u003c\/strong\u003e is a carbon fibre seatpost built to handle the competing demands of road performance: light enough to justify its place on a race-ready build, yet tuned to absorb road vibration more effectively than a standard performance post.
