It’s the aero road bike that Wout van Aert rode to the 2022 Tour de France Green Jersey by the biggest margin of victory in modern history — 480 points, 194 clear of his nearest rival. The new S5 builds on that legacy with a frame 6.3 Watts faster and 124 grams lighter than its predecessor. The biggest gains come at the front end: deeper fork legs and head tube, and a new one-piece carbon handlebar and stem that refines the iconic V-stem. Cervélo and Reserve co-developed the 57|64 Turbulent Aero wheelset specifically to complete the aerodynamic system — not an afterthought, but engineered together with the frame. All five builds at RA Cycles include those Reserve wheels, a power meter, and a one-piece carbon cockpit, across Ultegra Di2, Force AXS, Dura-Ace Di2, and Red AXS groupsets in Five Black, Carnelian, and Lithium colorways.\u003c\/p\u003e\u003c\/div\u003e","products":[{"product_id":"cervelo-s5-red-axs-bike-1","title":"Cervelo S5 Red AXS Bike","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003eCervelo S5 Red AXS Bike\u003c\/strong\u003e is the most refined version of Cervélo’s flagship aero road platform — the bike Jonas Vingegaard and Wout van Aert have used at the highest level of the sport. The current generation of the S5 improves aerodynamic efficiency by more than 6 watts over its predecessor while reducing overall weight by 124 grams, changes that Cervélo achieved through deeper fork legs, a refined head tube profile, and optimized carbon layup and hardware throughout the frameset. This SRAM Red AXS build arrives with a power meter already in the crankset, ceramic bearings in the bottom bracket, and the Reserve 57|64 asymmetric wheelset that was co-developed with Reserve specifically for this generation of the S5.\u003c\/p\u003e\n\u003cp\u003eThe frame is carbon monocoque, anchored by Cervélo’s All-Carbon Bayonet S5 fork — the structure that changed most significantly in this generation, with deeper fork legs that work in aerodynamic concert with the Reserve 57TA and 64TA wheel profiles. The asymmetric rim design of those wheels mirrors the asymmetric shape of the S5’s seat tube, so air moves across the frame and wheels as a cohesive system rather than as separate surfaces. Cervélo states the Reserve 57|64 combination delivers 3 watts of improvement over the previous Reserve 52|63 setup at equivalent weight. The DT Swiss 180 hubs in both wheels — front at 12x100mm, rear at 12x142mm — are among the lightest and most reliable hub systems in road cycling.\u003c\/p\u003e\n\u003cp\u003eThe HB19 integrated carbon cockpit uses Cervélo’s “Plus-Four” design: the brake hoods are positioned 4 centimeters narrower than the drops, encouraging a more aerodynamic upper-body position without compromising the stability and control you need during sprints and descents. Nine bar and stem combinations are available across the size run, and the system is fully UCI-legal. SRAM Red AXS E1 handles the shifting — 12-speed wireless electronic, with the Red crankset shipping with a dual-sided power meter installed. The bottom bracket is SRAM DUB Ceramic BBright, using ceramic bearings in Cervélo’s proprietary asymmetric BB shell. The cassette spans 10-33t, and the 50\/37 chainring combination provides close-ratio gearing through the middle of the range where race riding actually happens.\u003c\/p\u003e\n\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e6+ Watts Aero Improvement Over Previous Generation:\u003c\/strong\u003e Cervélo’s aerodynamic development on the current S5 produced more than 6 watts of improvement at race speed, driven primarily by the deeper fork legs and refined head tube profile that channel airflow more efficiently across the front of the bike.

The S5 isn't the lightest road bike Cervelo makes — that's the R5's job. The S5 exists to slice through the air faster than anything else at this price, and it does so with a precision that has made it the bike of choice for some of the best riders in professional cycling. Jonas Vingegaard and Wout van Aert have won races on it. Simon Yates has won races on it. The current generation is 6.3 watts faster than its predecessor while simultaneously shedding 124 grams — an improvement in two dimensions that doesn't happen by accident.\u003c\/p\u003e\n\u003cp\u003eThe aerodynamic gains are concentrated at the front end. Cervelo went significantly deeper on the fork legs and refined the head tube profile, producing smoother airflow into and around the frameset. The asymmetric seat tube profile integrates with the rear wheel as a cohesive system — air coming off the frame feeds cleanly into the wheel, not around it. This is not incidental. The Reserve 57|64 wheelset was co-developed with Reserve specifically for the S5's geometry, with the rear wheel's asymmetric profile engineered to match the seat tube cutout exactly. Those wheels are 3 watts faster than the previous Reserve 52|63 pairing while maintaining equivalent weight. Every aero gain on this bike compounds on the one before it.\u003c\/p\u003e\n\u003cp\u003eThe HB19 one-piece carbon bar and stem uses Cervelo's \"Plus-Four\" concept: the hood position is 4 centimeters narrower than the drops. This allows riders to hold a more aerodynamic position on the hoods — where most riding actually happens — without sacrificing stability during sprints or technical descents. Nine bar and stem size combinations are available, so achieving an aerodynamically optimized fit doesn't require compromise. The frame accepts those nine configurations at no additional cost when purchased through an authorized retailer, and the design is fully UCI-legal.\u003c\/p\u003e\n\u003cp\u003eThe drivetrain is Shimano Dura-Ace Di2 throughout — R9250 front and rear derailleurs with R9270 hydraulic disc levers and calipers. The crankset is Shimano Dura-Ace R9200 with a 54\/40T chainring setup and a 4iiii Precision Pro GEN3+ dual-sided power meter installed from the factory. You are getting left and right power data without an aftermarket installation, and the chainring spec reflects what this bike is built for: top-end speed on flat and rolling terrain. The cassette runs 11–34T in Dura-Ace R9200 12-speed, giving enough range for variable terrain while keeping the gearing optimized for the kinds of courses where the S5 belongs. The bottom bracket is a CeramicSpeed SL in BBright spec — one of the highest-performing BB options in cycling, and it comes standard.\u003c\/p\u003e\n\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e6.3 watts faster than the previous S5:\u003c\/strong\u003e A measurable, independently validated improvement — not a marketing estimate.

Cervelo has been building dedicated aero road bikes for two decades, and the current S5 represents the most resolved iteration of that work. Every element — frame, fork, cockpit, seat tube, and wheels — was co-developed as an integrated system rather than assembled from independent parts. The goal was to reduce aerodynamic drag at every contact point, and the design reflects that intent in every detail.\u003c\/p\u003e\n\u003cp\u003eThe carbon frame features an asymmetric seat tube shaped to match the profile of the rear wheel, eliminating the turbulence-generating gap that a round seat tube creates next to a deep-section wheel. Up front, the fork legs and head tube are deeper than the previous generation, and the one-piece integrated carbon bar and stem — Cervelo's Plus-Four concept — narrows 4cm at the hoods relative to the drops. That geometry reduces the frontal area your upper body presents at speed, where aerodynamic drag is the decisive variable. Cervelo's own testing places the current S5 at 6.3 watts faster than its predecessor. Despite an increase in surface area to achieve those gains, the frame is 124 grams lighter than the previous generation — a product of refined carbon architecture, not a tradeoff with stiffness or strength.\u003c\/p\u003e\n\u003cp\u003eThe Ultegra Di2 build pairs Shimano's 12-speed electronic groupset with a 52\/36T crankset and 11-34T cassette, running on a ceramic bottom bracket. Ultegra Di2 delivers consistent, instant shifting under any load — the same actuation logic and electronic precision as Dura-Ace Di2, with the long-term reliability that holds its adjustment over thousands of kilometers of hard riding. A power meter comes standard in this build, integrated into the crankset, removing a purchase you'd otherwise budget separately. The Reserve 57|64TA carbon wheelset with DT Swiss 240 hubs completes the package: a deep front-and-rear combination engineered for aerodynamic performance, with Swiss hub precision and engagement quality built for the long haul.

The Force AXS build at $10,250 puts SRAM's wireless electronic drivetrain — with an integrated Quarq power meter — on that platform alongside Reserve 52|63 co-developed carbon wheels and the HB19 one-piece integrated cockpit that makes the S5's front-end aerodynamics possible.\u003c\/p\u003e\n\u003cp\u003eThe S5 frame runs deep airfoil tube profiles with sharper trailing edges across the frame, fork, and cockpit, sculpted through wind tunnel iteration rather than CFD simulation alone. Despite increased surface area at the fork and head tube compared to the previous generation, the current S5 achieves 65 grams of additional drag reduction — a counterintuitive result that comes from managing how airflow interacts with the wheel, fork, and downtube as a system rather than optimizing each component in isolation. The Cervelo Bayonet S5 all-carbon fork (~395g) is integral to that system: its wide crown profile manages the airflow transition from the front wheel through the head tube and into the downtube in a way a conventional fork can't. Cables and hydraulic lines route through the frame internally via Cervelo's BBright-integrated cable management system, emerging cleanly at the derailleur and calipers without disrupting the surface. The PF BBright bottom bracket shell — Cervelo's proprietary 79mm design — provides a platform wide enough for DUB-spindle cranks with excellent bearing placement and stiffness. The frame weighs approximately 980g in size 56.\u003c\/p\u003e\n\u003cp\u003eThe HB19 cockpit is a one-piece integrated carbon bar and stem — no separate components, no gap between bar and stem to catch air. Cervelo's \"Plus-Four\" design runs the hood section 4cm narrower than the drop width, which narrows the rider's silhouette in the brake hood position while keeping a comfortable 36, 38, or 40cm drop section. The bar has 7° of flare, 75mm reach, and 125mm drop — proportions designed for riders who spend most of their time on the hoods in a race or aggressive training position. Stem lengths run from 80mm to 150mm in 10mm increments, allowing a wide range of fit positions within the integrated system. All AXS connections and hydraulic lines run through the steerer and bar, with no external cables from stem to caliper.\u003c\/p\u003e\n\u003cp\u003eThe drivetrain is SRAM Force AXS — 12-speed wireless electronic, with the Force crankset running a 48\/35T configuration and an integrated Quarq power meter (±1.5% accuracy, dual ANT+\/Bluetooth). At $10,250, a factory power meter is a meaningful inclusion — no crank swap, no separate purchase, calibrated and ready from the first ride. A 10-33T Force cassette rounds out the drivetrain with the range for rolling and hilly terrain while keeping gear steps tight in the middle where most road riding happens. Braking is SRAM Force AXS HRD hydraulic disc with 160mm flat-mount rotors. The wheelset is Reserve 52|63 — a depth-matched carbon set (52mm front \/ 63mm rear) co-developed by Cervelo and Reserve specifically for the S5's aerodynamic profile. The 52|63 uses Reserve's Turbulent Aero platform, developed from real-world wind data rather than ideal tunnel yaw angles, and runs 25mm internal width up front and 24mm rear on DT Swiss 350 hubs with 24 spokes and Centerlock disc mounts. Vittoria Corsa N.EXT TLR 700x28c tires are fitted tubeless-ready. The Cervelo SP20 carbon aero seatpost and Prologo Dimension NDR T4.0 saddle (143mm) complete the build.\u003c\/p\u003e\n\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eWind tunnel-validated aero gains.\u003c\/strong\u003e 6.3 watts over the previous S5 and 8.7 watts over the nearest competitor aren't estimated figures — they come from a controlled wind tunnel session using a consistent test protocol.

The S5's V-stem and bayonet fork have spent years at the front of the professional peloton — Wout van Aert rode this shape to the biggest margin of victory in a modern Tour de France Green Jersey competition, and Simon Yates wore the maglia rosa on it at the Giro. This build pairs the current S5 frame with SRAM's wireless Red AXS drivetrain and Reserve carbon wheels, priced at $14,500.\u003c\/p\u003e\n\u003cp\u003eCervelo says the latest S5 is more than 6 watts faster than its predecessor and roughly 124 grams lighter, with most of that gain coming from a reworked front end — deeper fork legs and a taller head tube that grow the frontal profile in a way that reduces drag rather than adding it. The bayonet fork itself extends up alongside a widened head tube and blends directly into the down tube, a shape that's carried the S5's identity across multiple generations even as the tube profiles around it evolved. Further back, asymmetric shaping at the seat tube and rear wheel junction picks up additional aero savings, since a meaningful share of a bike's drag comes from how cleanly air moves around that area. This specific build weighs 6.74kg, light for a bike built primarily around aerodynamics rather than climbing weight.\u003c\/p\u003e\n\u003cp\u003eThe drivetrain is where this build breaks from a typical two-ring setup. SRAM's Red AXS E1 group runs a single 50t Aero chainring on a Red 1 AXS crank with an integrated power meter, paired with a wide 10-36, 12-speed cassette — there's no front derailleur to shift and no chainring to drop into, which means one fewer moving part in the wind and one less thing to think about mid-sprint. The 10-36 spread still covers real climbing even off a single ring, backed by a SRAM DUB ceramic bottom bracket and Red E1 hydraulic disc brakes on Centerlock rotors. Shifting and braking are both wireless and electronic, so there's no housing routed through the frame to interrupt the aero shaping built into the front end.\u003c\/p\u003e\n\u003cp\u003eWheels are Reserve 42mm front and 49mm rear carbon rims on DT Swiss 180 hubs, tubeless compatible on 12x100mm and 12x142mm thru-axles. Reserve co-developed its aero wheel lineup with Cervelo specifically around the S5 frame, and the shallower 42\/49 depth on this build trades some top-end aero gain for a wheelset that handles crosswinds more predictably than the deeper 57\/64 option Cervelo specs on its flagship S5 build. Vittoria Corsa Pro TLR tires in a 700x29 tubeless width round out the rolling stock. Up front, a Cervelo HB19 carbon bar and stem keep this build on a conventional two-piece cockpit rather than the one-piece aero bar used higher in the S5 lineup, which simplifies fit adjustments if reach or stack needs to change after the sale. A Cervelo SP34 carbon seatpost and Fizik Arione R1 Light saddle finish the seated position, and the frame includes Cervelo's front and rear accessory mounts for a computer or light without adding a separate clamp.\u003c\/p\u003e\n\u003cp\u003eGeometry spans six sizes, 48cm to 61cm, with reach growing from 367mm to 409mm across the range — enough spread that most riders can dial in position without needing the fit service Cervelo built around the one-piece cockpit elsewhere in the S5 lineup. This is a bike for a rider chasing speed on flat and rolling roads, someone racing breakaways or time trials disguised as road stages, who wants Cervelo's aero platform and a simplified 1x drivetrain without the fit constraints of an integrated bar.

This build pairs the S5 frame with a full SRAM Red AXS E1 wireless groupset, and at $14,500, it represents the top of the S5 lineup alongside Cervélo's Shimano Dura-Ace Di2 build on the same frame.\u003c\/p\u003e\n\n\u003cp\u003eThe current S5 is a redesign of a bike that's already been a fixture at the front of the professional peloton, and Cervélo says this generation is over 6 watts faster than its predecessor while shedding 124 grams. Most of that gain comes from the front of the bike: deeper fork legs and a deeper head tube reduce drag, and the frame pairs with a one-piece carbon cockpit that builds on the S5's original V-stem concept. Cervélo also reshaped the seat tube and rear wheel cutout with asymmetric profiles to manage airflow around the rear end, an area the brand points to as a meaningful source of the bike's aerodynamic gains. It's an aero road bike in the strictest sense — nearly every tube and junction on the frame is there to solve a wind problem, not just a structural one.\u003c\/p\u003e\n\n\u003cp\u003eCervélo co-developed the Reserve 57|64 Turbulent Aero wheelset specifically for the S5 frame, and this build comes with that wheelset as stock: a 57mm-deep front and 64mm-deep rear, both tubeless compatible and built on DT Swiss 180 hubs. Reserve's Turbulent Aero program uses real-world wind data rather than pure wind-tunnel numbers to shape the rims, aiming for wheels that hold their aero advantage in actual crosswinds and traffic-disturbed air, not just in a controlled test environment. Pairing a wheelset designed alongside the frame, rather than bolted on afterward, is part of how Cervélo frames the S5 as a complete aero system rather than just an aero-shaped tube set.\u003c\/p\u003e\n\n\u003cp\u003eOn the drivetrain side, this build runs SRAM's Red AXS E1 groupset end to end: wireless electronic shifting across a 12-speed cassette, Red AXS hydraulic disc brakes on SRAM Paceline X Centerlock rotors, and a Red AXS crankset with 50\/37 chainrings and a built-in power meter, mounted to a ceramic BBright bottom bracket. The 10-33 cassette gives a reasonably wide gear range for an aero race bike, useful on rolling terrain without needing a second, more relaxed bike. Vittoria Corsa Pro TLR tubeless tires come mounted at 700x29, and a Fizik Arione R1 Light saddle and Cervélo's SP34 carbon seatpost round out the contact points. Cervélo highlights results like Wout van Aert's Green Jersey win by the largest margin of victory in modern Tour de France history and Simon Yates riding into the maglia rosa as evidence that this frame's aero shaping and handling hold up at the top level of racing.\u003c\/p\u003e\n\n\u003cp\u003eBecause a one-piece bar and stem can't be swapped the way a standard cockpit can, Cervélo builds the S5 in nine different frame and bar\/stem size combinations, and an authorized retailer fits the correct combination at no additional cost when the bike is purchased. This build is available in Five Black across six frame sizes from 48cm to 61cm. For a rider chasing outright speed on flat and rolling terrain, whether that's a criterium, a fast group ride, or a time-sensitive century, the S5 Red AXS is built specifically for that job.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Cervelo","offers":[{"title":"Reef Blue \/ 48cm","offer_id":45779723059244,"sku":"0M0S5GRX2C48","price":14500.0,"currency_code":"USD","in_stock":true},{"title":"Reef Blue \/ 51cm","offer_id":45779723092012,"sku":"0M0S5GRX2C51","price":14500.0,"currency_code":"USD","in_stock":true},{"title":"Reef Blue \/ 54cm","offer_id":45779723124780,"sku":"0M0S5GRX2C54","price":14500.0,"currency_code":"USD","in_stock":true},{"title":"Reef Blue \/ 56cm","offer_id":45779723157548,"sku":"0M0S5GRX2C56","price":14500.0,"currency_code":"USD","in_stock":true},{"title":"Reef Blue \/ 58cm","offer_id":45779723190316,"sku":"0M0S5GRX2C58","price":14500.0,"currency_code":"USD","in_stock":true},{"title":"Reef Blue \/ 61cm","offer_id":45779723223084,"sku":"0M0S5GRX2C61","price":14500.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 48cm","offer_id":45779722862636,"sku":"0M0S5GRX1C48","price":14500.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 51cm","offer_id":45779722895404,"sku":"0M0S5GRX1C51","price":14500.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 54cm","offer_id":45779722928172,"sku":"0M0S5GRX1C54","price":14500.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 56cm","offer_id":45779722960940,"sku":"0M0S5GRX1C56","price":14500.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 58cm","offer_id":45779722993708,"sku":"0M0S5GRX1C58","price":14500.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 61cm","offer_id":45779723026476,"sku":"0M0S5GRX1C61","price":14500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/CERVELO-S5-RED-E1-2027-REEF-BLUE_c42eef29-b834-4ed9-a0d0-abe8226c881f.jpg?v=1783529384"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/collections\/cervelo-s5-336027.jpg?v=1737730817","url":"https:\/\/ricycles.com\/collections\/cervelo-s5.oembed","provider":"RA Cycles","version":"1.0","type":"link"}
