Designed for the 2016 Rio Olympics, this pursuit track frame was Argon 18's answer to a precise brief: build the fastest pursuit bike for the world's top national federations. The \"Engineered for Gold\" framing is not a marketing tagline — it describes the actual design mandate. Argon 18 supplied this frame to elite national programs competing at the Rio Games, and the result is a Pro Level carbon platform that balances maximum stiffness, aerodynamic tuning, and a pursuit-specific geometry that converts raw power into velodrome speed.\u003c\/p\u003e\n\n\u003cp\u003eTrack cycling leaves no room for mechanical softness. There are no derailleurs to manage, no terrain variables to absorb, no coasting to recover. Every design decision on the Electron Pro RIO comes back to two questions: how efficiently can the frame transmit power to the rear wheel, and how little drag can it generate while doing it? The frame responds immediately to hard accelerations and holds a rigid line through the banking, while the aerodynamic tube profiles minimize frontal drag in the pursuit tuck position. This is a machine built around the four-kilometer effort — demanding, unforgiving, and fast when everything is set up correctly.\u003c\/p\u003e\n\n\u003cp\u003eThis is a frameset. It ships with the Argon 18 Electron Pro RIO Pursuit seatpost and an FSA integrated headset — everything else, from the crankset and bottom bracket to pursuit bars and wheels, is built to spec by the buyer. That is a feature, not a limitation. Elite track programs and national squads work to precise component specifications, and the Electron Pro RIO gives them a world-class foundation to build on without locking them into a particular drivetrain or bar system.\u003c\/p\u003e\n\n\u003ch3\u003ePro Level Carbon and Track Geometry\u003c\/h3\u003e\n\u003cp\u003eThe frame and fork use Argon 18's Pro Level Carbon Layup — the top tier of construction in their lineup, developed for professional and elite racing applications. The layup prioritizes torsional stiffness at the bottom bracket and down tube, where sprint and pursuit efforts generate the highest bending loads. There is no compliance tuning here, no road-smoothing flexibility built into the layup. The carbon works in one direction: getting power from the pedals to the rear wheel as directly as possible.\u003c\/p\u003e\n\n\u003cp\u003eArgon 18's Track Geometry system defines the handling character throughout. The seat tube runs at 76 degrees across all sizes — steep enough to position the rider's hips directly over the pedals for efficient power delivery in the pursuit tuck. The head tube holds at 72.7 degrees, and chainstays are a consistent 375mm across the size range. Short, stiff, and forward: this is geometry designed to turn power output into forward motion, not to absorb road variation that doesn't exist on a velodrome surface.\u003c\/p\u003e\n\n\u003ch3\u003eArgon Oneness System\u003c\/h3\u003e\n\u003cp\u003eThe cockpit is built around Argon 18's Oneness System — an integrated stem and bar platform that combines precise rider positioning with high torsional stiffness and leading-edge aerodynamics. The system provides approximately 30 different cockpit configuration options, which gives fitters and coaches the range needed to dial in position across multiple riders and events without compromise. The Oneness System is also designed to be disassembled and packed for travel, a practical consideration for national programs moving equipment between competitions.\u003c\/p\u003e\n\n\u003cp\u003eFor pursuit configuration, the Electron Pro RIO is designed to accept Argon 18's pursuit handlebar extensions — sold separately in four lengths from 240mm to 300mm, all UCI compliant. Wind tunnel data shows that rider position accounts for roughly 80% of total aerodynamic drag on a track bike, and the pursuit bar geometry is built to address this directly: extensions designed to hug the rider's forearms closely in full aero position, reducing frontal area and helping maintain the optimal tuck across the full duration of a pursuit effort.\u003c\/p\u003e\n\n\u003ch3\u003eBuild Details and Sizing\u003c\/h3\u003e\n\u003cp\u003eThe Electron Pro RIO Pursuit Frameset is available at RA Cycles in sizes XS through L. The bottom bracket shell is BSA English threaded, compatible with standard track cranksets and bottom bracket systems. Wheel size is 700c throughout. The frameset ships in Black Matte \/ Red Gloss. The included FSA MR055E\/MR054 headset is a press-fit integrated design.

The \u003cstrong\u003eArgon 18 Electron Pro RIO Sprint Frameset\u003c\/strong\u003e is the most visible result of that track program. The \"RIO\" name marks its development context: this frame was engineered for the 2016 Rio Olympics, created in close collaboration with national federations aiming for the podium at the world's fastest velodromes. It's now available as a production frameset for elite riders and serious competitive track cyclists. At $6,300, this is not a general-purpose track bike — it's a dedicated sprint frameset built for the explosive power and aerodynamic precision that velodrome sprint disciplines demand.\u003c\/p\u003e\n\n  \u003cp\u003eThe frame and fork are constructed with Argon 18's Pro Level Carbon Layup — the top tier of their construction program. This layup uses lightweight carbon fiber formed into aerodynamically optimized tube profiles, with each tube's cross-sectional shape selected to reduce drag while maintaining the torsional stiffness sprint performance requires. A carbon frame that flexes under the load of a standing sprint bleeds power; the Pro Level Layup is designed to prevent exactly that, translating the full force of a sprint effort directly into forward motion. The BSA English threaded bottom bracket shell keeps the drivetrain interface conventional, reliable, and straightforward — a practical choice for team mechanics and serious club riders who service their own equipment.\u003c\/p\u003e\n\n  \u003cp\u003eArgon 18's Track Geometry is a design framework built around a single goal: converting maximum power output into speed on the track. The Electron Pro RIO Sprint runs a 76-degree seat tube angle across all four sizes (XS through L), combined with a 72.7-degree head tube angle and 375mm chainstays consistent across the full size run. The steep seat tube places the rider over the bottom bracket in a position that maximizes load on the major power-producing muscle groups at the peak of the pedal stroke. The short 375mm chainstays minimize rear-end flex and keep drivetrain response immediate — there's no lag between pedal input and rear-wheel acceleration. The 72.7-degree head tube angle and short fork rake produce precise, direct front-end handling at velodrome speeds. These geometry choices aren't adapted from road or endurance disciplines — they're specific to what sprint track racing actually requires.\u003c\/p\u003e\n\n  \u003cp\u003eThe cockpit of the Electron Pro RIO Sprint is built around Argon 18's dedicated sprint handlebar — an Argon 18 proprietary design, sold separately and not included with the frameset — engineered for the grip requirements, hand position, and aerodynamic demands of sprint discipline. The system supports approximately 30 different configuration options through a combination of adjustable stack, reach, bridge angle, and bar positioning, giving riders and their technical staff the ability to dial in precise positioning for individual biomechanics. Argon 18's Fit System extends this adjustability across the full size run, ensuring consistent fit quality from XS to L. The frameset is completed by an FSA MR055E\/MR054 headset and an Argon 18 Electron Pro RIO Sprint seatpost. Budget for the sprint handlebar as a separate purchase — it's the next critical step after the frameset.\u003c\/p\u003e\n\n  \u003cp\u003eThe Electron Pro RIO platform comes in two configurations: the Sprint Frameset presented here ($6,300) and the Pursuit Frameset ($7,200). These are distinct framesets — not the same carbon platform adapted with a different cockpit — each optimized for the geometry, handling, and power demands of their respective event. The Sprint is built for the short, explosive efforts of sprint disciplines; the Pursuit is designed around the sustained aerodynamic demands of individual and team pursuit. Four sizes (XS through L) are available in a single colorway: Black Matte \/ Red Gloss. The Electron Pro RIO Sprint is the track frameset Argon 18 built for racing at the world's highest level — and it performs accordingly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Argon 18","offers":[{"title":"Black Matte \/ Red Gloss \/ XS","offer_id":43505905991724,"sku":"ELEP.XS.306A.FS","price":6300.0,"currency_code":"USD","in_stock":true},{"title":"Black Matte \/ Red Gloss \/ S","offer_id":43505905958956,"sku":"ELEP.S.306A.FS","price":6300.0,"currency_code":"USD","in_stock":true},{"title":"Black Matte \/ Red Gloss \/ M","offer_id":43505905926188,"sku":"ELEP.M.306A.FS","price":6300.0,"currency_code":"USD","in_stock":true},{"title":"Black Matte \/ Red Gloss \/ L","offer_id":43505905893420,"sku":"ELEP.L.306A.FS","price":6300.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/argon-18-electron-pro-rio-sprint-frameset-1812765.jpg?v=1771302559"},{"product_id":"argon-18-electron-pro-tko-pursuit-frameset","title":"Argon 18 Electron Pro TKO Pursuit Frameset","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003eArgon 18 Electron Pro TKO Pursuit Frameset\u003c\/strong\u003e was built for one purpose: pursuit racing at the Olympic level. TKO stands for Tokyo — this is the frameset Argon 18 developed in partnership with Cycling Australia for the 2020 Tokyo Olympics, the product of over 4,500 hours of engineering, design, modelling, and wind tunnel testing conducted alongside Zipp, Monash University, and the University of Adelaide.

Tube shapes were developed computationally and refined in collaboration with university engineering partners, producing a profile calibrated specifically to the body position and racing speeds of elite pursuit competition — typically above 50 km\/h in a fully extended, low time-trial position. Every tube junction and surface transition was optimized as part of the development process rather than adapted from a road or criterium platform. The geometry carries that same race-specific intent: a consistent 76° seat angle and 72.7° head angle across all four sizes establish the forward weight bias and precise handling character pursuit racing demands, while 375mm chainstays keep the rear end compact and efficient across the size range.\u003c\/p\u003e\n\u003cp\u003eBuilt on Argon 18's Pro Level Carbon Layup, the TKO Pursuit delivers a 2% increase in bottom bracket stiffness and a 9% increase in torsional stiffness compared to the Electron Pro RIO — the frame that preceded it at Argon 18's competitive peak. On a track, stiffness has a direct relationship with speed: a stiffer frame converts more of each pedal stroke into forward motion, with less energy absorbed laterally or returned out of phase. The Pro Level Carbon construction achieves those stiffness gains without a weight penalty — the frame remains light enough to be competitive in events where power-to-weight matters as much as aerodynamics. Argon 18's Oneness System handles the cockpit interface, combining precise rider positioning, structural stiffness, aerodynamic integration, and travel-friendly assembly in a proprietary system designed for team and elite individual use. The included Electron TKO Pursuit handlebar and extensions complete the aerodynamic front end, purpose-built to match the frame's aero profile rather than adapted from a road or triathlon cockpit.\u003c\/p\u003e\n\u003cp\u003eThe TKO Pursuit's feature set reflects its intended competition context in ways most framesets do not bother with. An integrated datalogger bay lets teams capture performance data without external attachments that would compromise the frame's aero profile. A speed sensor mount and timing chip bracket are built directly into the frame. Chain tensioners and a saddle rail clamp are included. Cockpit swap capability allows position adjustments or rider changes without full disassembly — practical for national team setups and multi-rider programs. This is a frameset that was engineered with the full infrastructure of Olympic track cycling in mind, not retrofitted with competition features after the fact.\u003c\/p\u003e\n\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eOlympic-level aerodynamic development:\u003c\/strong\u003e Tube shapes and front profile were developed through 4,500 hours of engineering with Zipp and university research partners — not wind tunnel estimates, but a full competitive development program targeting Olympic pursuit performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e9% torsional stiffness gain:\u003c\/strong\u003e The Pro Level Carbon Layup delivers measurable stiffness improvements over the previous generation, translating directly to more efficient power transfer on the track where every watt matters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePursuit-specific geometry:\u003c\/strong\u003e The 76° seat angle, compact chainstays, and consistent geometry across sizes are built around the extended aerodynamic position of pursuit racing, not adapted from a road frame.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOneness System cockpit integration:\u003c\/strong\u003e The proprietary cockpit interface delivers aero, stiffness, and positioning precision in one system — and the included TKO Pursuit bars and extensions are designed as part of the frame's aerodynamic package, not an afterthought.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompetition-ready integration:\u003c\/strong\u003e Datalogger bay, sensor mount, timing chip bracket, and cockpit swap capability are built in — features that matter at the national and Olympic team level where equipment must perform without aerodynamic compromise.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003eFinal Take\u003c\/h3\u003e\n\u003cp\u003eThe Electron Pro TKO Pursuit Frameset is a purpose-built competition tool developed alongside the riders who race for Olympic medals.

Argon 18 is a Montreal-based brand with a focused track racing pedigree, and the Electron Pro is the bike they've refined across multiple Olympic cycles. TKO stands for Tokyo — this generation was developed specifically for the Tokyo Games, building on the Rio version with targeted improvements in aerodynamics and stiffness. This is not a track frame adapted from road geometry or designed for recreational velodrome riding. It is built at the level where hundredths of a second decide the result.\u003c\/p\u003e\n\n  \u003cp\u003eDevelopment of the Electron Pro TKO involved more than 4,500 hours of engineering across a formal partnership between Argon 18, Cycling Australia, Zipp, Monash University, and the University of Adelaide. That combination brought structured academic and aerodynamic research methodology to the design process — computational modeling, wind tunnel analysis, and structured on-track validation. The outcome is a frame with a reworked aero front profile and optimized tube shapes, delivering a 2% stiffness increase at the bottom bracket and 9% torsional stiffness increase over the Rio generation. The Pro Level Carbon Layup is Argon 18's highest-specification construction, applied to both the frame and fork. The bottom bracket is BSA English threaded — serviceable and compatible with a wide range of track crankset options.\u003c\/p\u003e\n\n  \u003cp\u003eThere are two configurations of the Electron Pro TKO: the Sprint and the Pursuit. They differ in fork offset and geometry tuning. The Sprint is set up for the explosive power demands of events like keirin, match sprint, and team sprint — events where the rider goes from a standing start or slow roll to maximum velocity in the shortest possible time. If sprint events are the focus, this is the correct frameset.\u003c\/p\u003e\n\n  \u003ch3\u003eTrack Geometry\u003c\/h3\u003e\n\n  \u003cp\u003eThe Electron Pro TKO Sprint runs geometry that is single-purpose and unapologetic about it. The seat tube angle is 76 degrees across all sizes — steep enough to position the rider directly over the pedals and load the hip and quad for maximum sprint power transfer. The head tube angle is 72.7 degrees, consistent across the full size range, giving the front end a quick, precise feel at speed. Chainstay length is 375mm across every size — extremely short, generating the instantaneous rear-wheel response a sprint rider needs when standing to accelerate. There is no softening of these numbers toward versatility or all-day comfort. Stack ranges from 461mm (XS) to 654mm (L) at RA Cycles, giving meaningful fit range within a geometry that stays uncompromisingly track-specific.\u003c\/p\u003e\n\n  \u003ch3\u003eArgon Oneness Cockpit System\u003c\/h3\u003e\n\n  \u003cp\u003eThe Electron Pro TKO Sprint uses Argon 18's Oneness cockpit system — an integrated platform combining precise positioning, high structural stiffness, and travel-friendly assembly. The system offers approximately 30 different configuration options for stack and reach, allowing the rider to arrive at a precise, UCI-legal sprint position. The Sprint handlebar — Argon 18's dedicated sprint bar with drop geometry suited to the event's demands — is sold separately and is not included with this frameset. It is not optional; it is required to complete the cockpit.

It looks exactly like a standard gravel bike at first glance but adds an extra kick while in the saddle. With this gravel build and the extra eBike boost, the Subito E-Gravel can help you keep up with partners, extend your ride, or help you conquer terrain that was never before possible. A hub motor installed in the rear wheel will make sure riders have the exact amount of power they need to keep moving without losing the riding experience.\u003c\/p\u003e\n\u003cp\u003eThe frame of the Subito E-Gravel is made with a lightweight carbon fiber layup.

Like all Argon 18 bikes, the geometry is adjusted along each frame size, assuring the perfect riding position regardless of the rider’s body type. A 3D system is new to the Subito which offers three headtube heights for each size to customize fit without sacrificing rigidity.

Argon 18 has been designing triathlon and time trial frames since 1989, and the E-117 carries that experience into a complete race build: carbon frame and fork, full Shimano Ultegra Di2 electronic shifting, an integrated brake system, Scope R5 57mm carbon wheels, and the brand's proprietary 3D fit system. At $7,999, it arrives as a race-ready machine built around solving triathlon's most persistent challenge — fitting the rider correctly without compromising the bike's aerodynamics.\u003c\/p\u003e\n\u003cp\u003eThe 3D System is the headline feature of the E-117, and it's a substantive engineering difference rather than a marketing label. Traditional triathlon cockpits offer roughly 30mm of available stack adjustment, which forces many athletes into positions that don't fully match their fit or toward aftermarket solutions that add drag. Argon 18's 3D System replaces the conventional top bearing arrangement with a custom spacer in which the bearing is integrated, available in three different heights for each frame size. The result is 60mm of available stack adjustment — double the conventional range — without stacking standard spacers. The integrated bearing design also preserves 5–11% more frontal rigidity than standard spacers at equivalent heights, so the additional adjustability doesn't trade away cockpit stiffness. For athletes who revisit their fit seasonally or build toward different race distances over time, this system is genuinely useful across the life of the bike.\u003c\/p\u003e\n\u003cp\u003eThe geometry is engineered specifically for long-course triathlon. A 78° seat tube angle across all five sizes positions the rider aggressively over the pedals — loading the posterior chain for sustained power output while reducing anterior muscle strain during the bike-to-run transition. The 413mm chainstay is consistent across the full size range. Stack and reach adjustability is wide: the medium size accommodates armpad stack from 576 to 700mm and armpad reach from 425 to 523mm, covering a broad range of athlete proportions without custom fabrication. The Argon 18 Integrated Cockpit pairs with 51 Speedshop Custom Extensions — airfoil-profiled to reduce drag at the arm interface — on a 40cm bar width suited to most triathlon athletes.\u003c\/p\u003e\n\u003cp\u003eThe integrated brake system is an aerodynamic decision with a functional payoff. Housing the brake calipers within the frame structure eliminates drag at the fork crown and rear triangle, where externally-mounted calipers create significant turbulence. TRP TR140-25 rotors at 140mm provide the braking performance. The drivetrain is Shimano Ultegra Di2 throughout — R8150 front and rear derailleurs, R8100 crankset with 52\/36 chainrings, Shimano SM-BB72 bottom bracket, and 12-speed 11-30T cassette. Shimano SW-R9150 sprint shifters mounted at the bar ends keep shifting accessible from the aero position without moving the hands.\u003c\/p\u003e\n\u003cp\u003eScope R5 57mm carbon disc wheels run front and rear — tubeless-ready and deep enough for aerodynamic advantage on the flat and rolling courses that define long-course triathlon. Vittoria Corsa N.EXT TLR 700x28 tires pair rolling resistance performance with tubeless puncture resistance for race-day reliability. The ISM PR1.0 saddle is engineered for the forward pelvic rotation that a 78° seat angle creates — it eliminates soft-tissue pressure in the aero position without requiring saddle tilt adjustments that undermine position accuracy.

At $4,399, it's the most accessible way into the E-117 frame and cockpit design, sitting at the base of a lineup that extends through Shimano Ultegra Di2 and SRAM Force AXS configurations at significantly higher prices. The bike arrives fully assembled with aerobars, wheels, brakes, and saddle spec'd out. Pedals are the only thing left to add.\u003c\/p\u003e\n\n  \u003cp\u003eThe E-117's carbon frame is built around a triathlon-specific geometry that holds a 78-degree seat tube angle across all five sizes — XS through XL. That steep angle rotates the rider's hips forward relative to a road bike position, reducing the hip angle at the top of the pedal stroke. In triathlon, that matters specifically for the run: a more open hip angle on the bike preserves range of motion in the hip flexors, which translates to a more natural running stride off T2. Chainstays hold at 413mm across all sizes, and the head tube holds at 72 degrees, producing consistent front-end geometry from the smallest to the largest frame. The bike is designed to put riders in an aggressive aero position and keep them there comfortably for the duration of the bike leg.\u003c\/p\u003e\n\n  \u003cp\u003eThe fit system that distinguishes the E-117 frame is Argon 18's 3D System. On most tri bikes, handlebar height is adjusted by stacking spacers below the stem — a method that introduces compliance into the steerer and can allow the front end to flex slightly under hard efforts. The 3D System raises the top bearing instead of adding spacers, integrating the head tube extension as a structural component rather than a stack of separate parts. Each frame size supports up to three extension heights, allowing the stack height to be adjusted without any loss of headtube stiffness. Custom 3D caps seal the headset at each extension height, keeping the cockpit profile clean. The geometry chart reflects this: each size shows a stack range rather than a fixed number — the XS spans 583mm to 612mm, the XL from 661mm to 690mm — representing the adjustment window the 3D System provides within a single frame.\u003c\/p\u003e\n\n  \u003cp\u003eShifting is handled by the Shimano 105 R7100 groupset — the 12-speed generation of Shimano's mid-range offering, running a 52\/36 chainring setup. Crank arm length is size-specific: 165mm for XS and S, 170mm for M and L, and 172.5mm for XL. The cassette is an 11-34 12-speed, wider than a typical road race setup and appropriate for triathlon courses with climbing or for athletes who want flexibility across different race venues. Shifting on the aerobars is handled by Microshift TT\/Tri bar end shifters, compatible with the Shimano drivetrain. Braking uses Argon 18's Integrated Brake System with TRP TR140-25 140mm rotors — hydraulic calipers routed through the integrated tri cockpit.\u003c\/p\u003e\n\n  \u003cp\u003eThe cockpit is built around an Argon 18 carbon basebar paired with a Profile Design 1\/Seventeen -17-degree stem and Profile Design Sonic\/Ergo\/39a aerobars at 400mm with 10mm pads.

At $6,699, it arrives as a complete package — the E117 carbon frameset, Shimano 105 Di2 electronic shifting, ATTEN L42 wheels, and 51 Speedshop tri extensions fitted from the factory. The spec doesn't ask you to substitute anything before your first race. The bike handles that for you.\u003c\/p\u003e\n\n\u003cp\u003eThe E117 carbon frame is Argon 18's dedicated triathlon platform, engineered specifically for multisport demands rather than adapted from a road design. Its 78-degree seat tube angle — consistent across all five sizes — positions the rider forward over the bottom bracket, shifting load away from the quads and hamstrings during the bike leg. That preservation matters most at the bike-to-run transition, where poor saddle positioning accumulates as muscle fatigue over distance. Argon 18 extends this thinking into the frame geometry itself through the Argon Fit System: bottom bracket drop, chainstay length, and wheelbase are adapted per frame size, and the fork is custom to each size to prevent toe overlap. A rider on a size XS — designed for a 47-50cm rider — gets geometry proportional to their body, not a compressed version of a larger frame. The 3D System handles front-end fit at the head tube, allowing stack height adjustment without a fork swap and without compromising steerer stiffness — practical for a triathlete still dialing in position between events. Cables are fully integrated throughout the frameset.\u003c\/p\u003e\n\n\u003cp\u003eShimano 105 Di2 handles the drivetrain. The R7150 derailleurs run on the same electronic architecture as Dura-Ace and Ultegra — identical shift logic, multi-shift capability, and junction box electronics, with a performance gap that narrows considerably once you're on the road. The 52\/36 chainring setup and 11-34 cassette give useful range across sprint-distance flat courses and longer events with elevation. Sprint shifters at the bar ends keep gear access within reach without requiring you to leave the aero position. The cockpit is Argon 18's own integrated system — stem and bar as a single unit — paired with 51 Speedshop Custom Extensions. Those extensions use an airfoil cross-section and sit at a 30-degree grip angle, a neutral wrist orientation that reduces hand fatigue on sustained efforts. Braking runs through Argon 18's Integrated Brake System, with the calipers built directly into the frame structure rather than bolted externally — lower drag, cleaner lines.\u003c\/p\u003e\n\n\u003cp\u003eThe ATTEN L42 wheelset is Argon 18's own wheel brand, built around a 42mm rim profile. That depth balances aerodynamic gain against crosswind handling — more efficient than a shallow rim while staying predictable in mixed conditions. Vittoria Corsa N.EXT tubeless-ready tires in 700x28 run from the factory on the ATTEN rims, and the E117 frame clears up to 30mm, leaving the option to run slightly wider rubber on rougher courses. The ISM PR1.0 saddle is a deliberate tri-specific choice: the relieved-nose design allows forward pelvic rotation into the aero position without the pressure buildup that accumulates over distance on a standard road saddle — a detail that makes longer bike legs noticeably more manageable.\u003c\/p\u003e\n\n\u003cp\u003eThe E-117 105 Di2 fits two riders well: someone transitioning from a road bike into a purpose-built tri platform for the first time, and a more experienced short-course racer who wants electronic shifting without paying into the Ultegra or Dura-Ace tier. The size range runs XS through XL — broader than most in this category — and the Argon Fit System's per-size geometry means the bike performs as intended across the full range rather than concentrating fit quality around medium sizes. Available in Black Stealth and Flaming Red. For athletes ready to race on geometry built specifically for triathlon rather than adapted from it, the E117 is where to start.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Argon 18","offers":[{"title":"Flaming Red \/ XS","offer_id":43978249830444,"sku":"117D.XS.374B.3D.1","price":6699.0,"currency_code":"USD","in_stock":true},{"title":"Flaming Red \/ S","offer_id":43978249764908,"sku":"117D.S.374B.3D.1","price":6699.0,"currency_code":"USD","in_stock":true},{"title":"Flaming Red \/ M","offer_id":43978249732140,"sku":"117D.M.374B.3D.1","price":6699.0,"currency_code":"USD","in_stock":true},{"title":"Flaming Red \/ L","offer_id":43978249699372,"sku":"117D.L.374B.3D.1","price":6699.0,"currency_code":"USD","in_stock":true},{"title":"Flaming Red \/ XL","offer_id":43978249797676,"sku":"117D.XL.374B.3D.1","price":6699.0,"currency_code":"USD","in_stock":true},{"title":"Black Stealth \/ L","offer_id":44045874757676,"sku":"117D.L.374A.3D.1","price":6699.0,"currency_code":"USD","in_stock":true},{"title":"Black Stealth \/ M","offer_id":44045874790444,"sku":"117D.M.374A.3D.1","price":6699.0,"currency_code":"USD","in_stock":true},{"title":"Black Stealth \/ S","offer_id":44045874823212,"sku":"117D.S.374A.3D.1","price":6699.0,"currency_code":"USD","in_stock":true},{"title":"Black Stealth \/ XL","offer_id":44045874855980,"sku":"117D.XL.374A.3D.1","price":6699.0,"currency_code":"USD","in_stock":true},{"title":"Black Stealth \/ XS","offer_id":44045875118124,"sku":"117D.XS.374A.3D.1","price":6699.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/argon-18-e-117-105-di2-bike-6215326.jpg?v=1771293971"},{"product_id":"argon-18-e-119-tri-red-axs-bike","title":"Argon 18 E-119 Tri+ Red AXS Bike","description":"\u003cdiv\u003e\n\u003cp\u003eEvery second.

Built by the Montreal-based brand around their Pro Level Layup carbon, the E-119 Tri+ is engineered as a complete race system: frame and rider, cockpit and storage, brakes and aerodynamics, all treated as one integrated structure rather than a sum of components. The result is a bike that earns its place among the fastest triathlon platforms available.\u003c\/p\u003e\n\u003cp\u003eThe aerodynamic breakthrough on the E-119 Tri+ is the integrated brake system. Argon 18 built the disc calipers directly into the frame — an industry first — eliminating the protruding caliper bodies that generate drag on conventional disc brake tri bikes. This system-wide integration extends to an aero-optimized cockpit, a deep bento box built into the front end, and a hidden toolkit accessible through the bottom bracket area. The combined result of these frame optimizations and system integrations is a claimed 10-watt advantage over the previous-generation E-119 — a meaningful figure when it compounds over a 112-mile bike leg.\u003c\/p\u003e\n\u003cp\u003eThe cockpit is the Argon 18 Oneness System — an integrated unit combining basebar and stem in a single structure with precise adjustability. The Oneness System delivers high stiffness, leading-edge aerodynamics, and travel-friendly assembly: the cockpit can be broken down and reassembled quickly without requiring a mechanic. Aerobar extensions are 51 Speedshop custom units. The Argon Fit System ensures that geometry stays consistent across all five sizes — the 78-degree seat tube angle, 72-degree head tube angle, and 413mm chainstays are constant from XS to XL. Stack range is adjustable from 573 to 663mm on an XS, with reach running 414 to 501mm, reflecting the Oneness System’s significant positional range within each frame size.\u003c\/p\u003e\n\u003cp\u003eThe SRAM Red AXS E1 drivetrain runs through every contact point — derailleur, crankset, calipers, and chain — with wireless shifting via SRAM blip satellite shifters mounted on the aerobars for position-specific actuation. The crankset includes an integrated power meter, providing a data-complete race setup out of the box. Chainrings are 50\/37, running against a SRAM XG1290 10-33 cassette in 12-speed.

Where pure road bikes demand sacrifice and gravel bikes ask you to slow down, the Krypton holds a more useful line: fast enough for a spirited group ride, stable enough for a long day on mixed surfaces, and comfortable enough to want to repeat it. Argon 18 describes it plainly as their most versatile bike, and that clarity of purpose is evident in every decision made on this frame.\u003c\/p\u003e\n\n  \u003ch3\u003eFrame Engineering\u003c\/h3\u003e\n  \u003cp\u003eThe Krypton's carbon frame is built around several interlocking technologies that work together rather than competing. The Topological Compliance System — Argon 18's approach to ride quality — decouples vertical flex from lateral stiffness by engineering compliance into specific areas of the frame. The result is a bike that absorbs road chatter and dampens vibration without going soft when you're putting power through it in a sprint or a sustained climb. Paired with Endurance Geometry, which positions the rider in a slightly more relaxed stance than a pure race bike, the Krypton is designed for the hours of riding where position fatigue becomes the limiting factor before fitness does. Argon 18 also applies size-specific geometry through their Argon Fit System, meaning the frame shapes shift as you move through the size run rather than simply scaling the same triangle up or down. XXS through XL riders each get a geometry calibrated to their proportions.\u003c\/p\u003e\n\n  \u003ch3\u003eShimano 105 Di2\u003c\/h3\u003e\n  \u003cp\u003eShimano's 105 Di2 groupset brings 12-speed electronic shifting to a price point that used to belong to mechanical-only builds. The R7150 derailleurs handle front and rear actuation with the same servo-motor precision as Shimano's higher-tier electronic systems — shifts are consistent whether you're pushing hard or soft-pedaling through a descent. R7170 levers integrate the controls with hydraulic disc brakes, and Shimano RT70 rotors at 160mm front and 140mm rear handle the stopping. A 50\/34 compact crankset paired with an 11-34T cassette gives the Krypton a wide spread for climbing without leaving gaps in the middle of the range. The Token T47 bottom bracket keeps the drivetrain running cleanly in a threaded shell format that's easy to service. Scope S4.A wheels carry Vittoria Corsa N.EXT G2.0 tires in 700x32 — wide enough to run at lower pressure for comfort and grip, narrow enough to hold reasonable pace on pavement.\u003c\/p\u003e\n\n  \u003ch3\u003eBuilt for the Long Haul\u003c\/h3\u003e\n  \u003cp\u003eArgon 18 engineered practical features into this frame that show up on the rides where they matter. The Integrated Toolkit is a storage compartment built into the downtube — space for a multi-tool, a tube, or an energy bar, accessed without a bag. On long days away from services, or on mixed routes where a saddle bag would create drag, that's genuinely useful. The 3D System refers to the headset design, which allows fit adjustments — height, reach, offset — without cutting the steerer or committing to a fixed stack. It's a small thing until you're trying to dial in position over a few months of riding, at which point the flexibility is significant. The Argon 18 TDS-C seatpost, FSA SMR stem, and FSA Energy SCR Compact handlebar round out the cockpit, with Ciclovation Leather Touch bar tape stock.\u003c\/p\u003e\n\n  \u003cp\u003eThe Krypton 105 Di2 is the entry point into the Krypton lineup, and the 105 Di2 groupset represents a genuine upgrade path from mechanical components rather than a compromise.

The Montreal-based brand has been engineering performance bikes since 1989, and the 2025 Dark Matter consolidates several proprietary technologies into a gravel-specific frame — 57mm tire clearance, integrated internal storage, a compliance system developed through individual frame analysis, and a fit architecture that covers more riders without external compromises. At $4,999, it's built around the SRAM Rival XPLR AXS E1 groupset, a 13-speed wireless 1x drivetrain that defines the current benchmark for gravel performance at this price.\u003c\/p\u003e\n\n\u003ch3\u003eFrame Engineering: TCS, 3D System, and Integrated Storage\u003c\/h3\u003e\n\u003cp\u003eFour of Argon 18's core technologies are built into the Dark Matter frame. The Topological Compliance System — TCS — is the most consequential for how the bike actually rides. It's a proprietary engineering method that analyzes each frame model individually to determine the optimal carbon layup topology for vertical compliance. Rather than applying a single compliance strategy across a product line, Argon 18 optimizes the fiber orientation and layup schedule for the Dark Matter specifically, targeting maximum absorption of road-induced vibration at the seatstays and rear triangle without introducing lateral flex that would bleed power during hard pedaling efforts. On a gravel bike ridden for hours on mixed surfaces, the difference between engineered compliance and stiffness-at-all-costs is felt in the lower back and hands well before the halfway point of a long day.\u003c\/p\u003e\n\u003cp\u003eThe 3D System addresses fit range. Argon 18 designed the head tube to accept up to 35mm of additional stack adjustment, giving each size a published stack range rather than a single fixed figure — the medium, for example, spans 582mm to 606mm of stack. This lets riders dial in position meaningfully without resorting to external spacers or steep-rise stems. Internal cable routing is fully integrated for both mechanical and electronic drivetrains. The Integrated Toolkit goes further: Argon 18's layup opens up the downtube for accessible internal storage, giving the rider a place to stow tools, nutrition, or small items without a frame bag attached.\u003c\/p\u003e\n\n\u003ch3\u003eSRAM Rival XPLR AXS: 13-Speed Wireless, Full Mount Derailleur\u003c\/h3\u003e\n\u003cp\u003eThe Rival XPLR AXS E1 rear derailleur uses SRAM's Full Mount interface — a design choice with real-world consequences. Traditional derailleur mounting uses adjustment screws that can vibrate out of spec on rough gravel, requiring regular re-tuning. Full Mount has no adjustment screws; the derailleur clamps rigidly to the frame and holds its position regardless of what the terrain does to it. Combined with wireless AXS shifting — no cables through the frame, no mechanical connections to corrode or stretch — the drivetrain is designed to require less intervention across a riding season. The 40T single chainring paired with a 10-46T 13-speed cassette covers the full range from sustained climbing to road-speed transitions between sections. The bottom bracket is SRAM DUB T47 Wide: a threaded interface that eliminates the creak and bearing longevity issues associated with press-fit standards. SRAM Rival AXS hydraulic disc brakes run 160mm Centerlock Paceline rotors at both ends.\u003c\/p\u003e\n\n\u003ch3\u003eWheels, Tires, and Cockpit\u003c\/h3\u003e\n\u003cp\u003eDT Swiss G1800 XDR wheels are the stock choice here — alloy gravel hoops built for durability, with DT's Ratchet freehub system and wide rims sized for tubeless setup. They're not carbon, which is appropriate for a bike positioned for adventure use where wheel resilience matters as much as weight. The Schwalbe G-One RX PRO in 700x50c tubeless-ready is a race-oriented gravel tire with paired outer blocks for cornering traction on technical surfaces and a souplesse casing that smooths the ride over irregular terrain. The frame clears 57mm, leaving meaningful room to run wider tires if the route calls for it. The FSA A-Wing Pro AGX handlebar is a flared aero drop bar designed for gravel positioning. The Argon 18 TDS-C seatpost — TDS standing for Tunable Deflection System — is a carbon post engineered to flex vertically for comfort on long rides while staying laterally stiff under pedaling load, working in concert with the TCS frame compliance rather than against it.\u003c\/p\u003e\n\n\u003ch3\u003eThree Colors, Six Sizes\u003c\/h3\u003e\n\u003cp\u003eThe Dark Matter Rival AXS XPLR is available in Anthracite, Root Beer, and Cactus Green across six sizes from XXS to XL, covering rider heights from roughly 44cm to 62cm seat tube.

Argon 18's answer was to model the complete system — bike and rider together — rather than optimizing the bare frame in isolation, and the result is a claimed 24 watts of savings at 45km\/h compared to the Sum Pro it replaces. At 6.95kg claimed in size medium with a power meter, integrated bottle cages, and a computer mount already included in that figure, the Nitrogen Pro arrives as a complete race bike with nowhere to hide and nothing left to add.\u003c\/p\u003e\n\u003cp\u003eThe frame is full high-modulus carbon built to Argon 18's Pro-level layup, the result of evaluating 130 different tube profiles before settling on the final shapes.

That last detail is what separates a bike that's fast from one you actually want to ride for four hours. The seat stays run horizontal and dropped, borrowing geometry from Argon 18's track bike program to reduce drag at the rear of the frame.

The cockpit is ATTEN's CHB-01 — an integrated one-piece aero bar and stem with an arrow-shaped cross-section, a 3° inward flare on the drops for ergonomic hand positioning, and a geometry that delivers 15mm more stack and 5mm less reach than the Sum Pro.

The Nitrogen Pro's design principle — model the complete system, bike and rider together, rather than optimizing the bare frame in isolation — produces a claimed 24 watts of savings at 45km\/h over the Sum Pro it replaces.

Bottom bracket stiffness is up 23% compared to the Sum Pro, head tube stiffness is up 6%, and the overall chassis is 18.5% stiffer — while maintaining equal vertical compliance. The seat stays run horizontal and dropped, borrowing geometry from Argon 18's track bike program to clean up drag at the rear of the frame. A T47 threaded bottom bracket shell fitted with a CeramicSpeed SLT DUB bearing, Universal Derailleur Hanger rear dropout, and fully internal cable routing complete the chassis foundation. The fork — the product of 25 prototypes — is 80% stiffer than the previous Nitrogen disc fork, with the front brake caliper tucked behind the fork legs and the crown recessed to form one continuous aerodynamic surface with the flow-optimized head tube. The ATTEN CHB-01 integrated one-piece bar and stem sits at the front, with an arrow-shaped cross-section and 15mm more stack and 5mm less reach than the Sum Pro — an aero position accessible to more riders.\u003c\/p\u003e\n\u003cp\u003eThe drivetrain is Shimano's Dura-Ace R9200 Di2 — the twelfth generation of a groupset that has defined the benchmark for electronic road shifting since it was introduced.

The FC-R9200 crankset runs 52\/36T chainrings paired with a CS-R9200 11-30T cassette — a 12-speed spread built for road racing and fast all-day riding in equal measure. Shimano Dura-Ace BR-R9270 hydraulic disc brakes with 160mm front and 140mm rear Shimano RT-CL900 rotors provide the stopping. The rest of the build carries through identically to the flagship configuration: ATTEN × Scope Artech 6.A+ wheels at 65mm rim depth, Vittoria Corsa Pro TLR 30mm tubeless tires, CeramicSpeed SLT headset, Repente Quasar CR 2.0 saddle, and the Nitrogen Pro integrated aero seatpost.\u003c\/p\u003e\n\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem-level aero that holds up on real roads\u003c\/strong\u003e — Argon 18's CFD work modeled bike and rider together, not just the bare frame.

The frame is built using Pro Level Layup — Argon 18's highest-grade carbon construction, the same methodology applied across all Nitrogen Pro builds regardless of groupset — delivering a frame that's stiffer and lighter than the Elite Level Layup found on the base Nitrogen. More than a frame upgrade, the Nitrogen Pro was designed as a complete system: the aerodynamic frame geometry, the ATTEN × Scope Artech 6.A+ wheels, and the ATTEN CHB-01 integrated cockpit were developed together to maximize performance as an integrated whole rather than as independently assembled parts.\u003c\/p\u003e\n\u003cp\u003eThe aerodynamic architecture draws directly from Argon 18's track and triathlon programs. The Flow-Optimized Headtube uses an extended volume and angled edge to reduce drag at the front of the bike. The dropped horizontal seat stays — a design borrowed from the Electron Pro TKO track bike and the E119 triathlon machine — clean up airflow around the rear wheel. An oversized bottom bracket area maximizes power transfer. Integrated bottle cage mounts, an aerodynamic carbon seatpost, and fully integrated internal cable routing remove every external snag point from the silhouette. This is aero design that compounds: each decision reinforces the others, producing a bike where aerodynamics and geometry work in the same direction. The Argon Fit System ensures the frame does all of this for every rider — each of the six sizes carries its own tuned geometry, not a scaled version of a single template.\u003c\/p\u003e\n\u003cp\u003eThe Ultegra Di2 build equips the Nitrogen Pro with Shimano's 12-speed electronic groupset at the second-tier level — fully electronic shifting via R8170 levers and R8150 derailleurs, a 52\/36T crankset paired with an 11-30T cassette, and Shimano Ultegra R8170 hydraulic disc brakes with CL800 rotors. Two CeramicSpeed bearing upgrades are standard across all Nitrogen Pro builds: CeramicSpeed SLT Bearings in the IST3 headset and a CeramicSpeed T47 Coated bottom bracket replace the conventional bearings found on the base model. The ATTEN × Scope Artech 6.A+ wheels were developed specifically for the Nitrogen Pro as part of the integrated system approach, paired with Vittoria Corsa Pro TLR 700×30 tires for a race-ready tubeless setup straight from 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\u003ePro Level Layup:\u003c\/strong\u003e Argon 18's highest-grade carbon construction is consistent across all Nitrogen Pro builds.

Argon 18 has been building bikes in Montreal since 1989, and the Nitrogen represents the brand's current answer to how fast a road bike can be while still being livable for real riding. The answer involves a flow-optimized headtube, dropped seat stays pulled from Argon 18's track bike DNA, and a geometry system calibrated per frame size rather than simply scaled — the kind of detail that separates a bike you can race from a bike you want to race.\u003c\/p\u003e\n\u003cp\u003eThe Nitrogen's carbon frame is built around Argon 18's Elite Level Layup at approximately 1,150g. The frame delivers through proprietary aero shaping: the Flow-Optimized Headtube uses extended volume with angled edges to reduce turbulence at the front end, the fork runs a wider and deeper profile for continued aero benefit through the front wheel zone, and the oversized bottom bracket area is engineered for direct power transfer under load. The dropped horizontal seat stays are a direct reference to the Electron Pro TKO and E119 track bikes — they stiffen the rear triangle while allowing the top tube to taper cleanly into the saddle area. Max tire clearance of 34mm, Universal Derailleur Hanger compatibility, and Argon 18's Argon Fit System — where geometry angles are independently optimized per size rather than proportionally scaled — complete a frame designed for the full XXS-to-XL range to handle correctly, not just the middle sizes.\u003c\/p\u003e\n\u003cp\u003eThe build makes the Nitrogen Ultegra Di2's value case against comparably priced competition. Shimano Ultegra Di2 R8150\/R8170 handles all shifting and braking — a complete 12-speed electronic groupset with hydraulic disc brakes, 52\/36 chainrings, and an 11-34 cassette that keeps the gearing range open for varied terrain. The wheels are 65mm deep Scope R6.A carbon discs — a depth that works directly within Argon 18's integrated aero system and pairs with 30mm Vittoria Corsa N.EXT TLR tubeless-ready tires. The ATTEN CHB-01 aero integrated handlebar provides an aerodynamically coherent cockpit, and the Repente Quasar 2.0 saddle completes the build.

The Nitrogen platform distills years of aerodynamic research from Argon 18's track and triathlon programs into a road frame that's fast without sacrificing the handling precision that makes a bike worth riding hard.\u003c\/p\u003e\n\u003cp\u003eThe carbon frame is built using Argon 18's Elite Level Layup — the same engineering approach used on their Pro-level bikes, applied to Elite-grade carbon fiber.

The result is a frame that reads as fast because it is fast, with no features included purely for appearance.\u003c\/p\u003e\n\u003cp\u003eThe 105 Di2 build equips this platform with Shimano's fully electronic 12-speed groupset — reliable, precise wireless-adjacent shifting via junction box and internal wiring, with a 52\/36T crankset and 11-34T cassette that handles everything from flat road sprints to sustained climbs. Braking comes from Shimano 105 R7170 hydraulic disc with Shimano CL700 rotors (160mm front, 140mm rear). Completing the package are the ATTEN L42 wheels — Argon 18's in-house 42mm deep carbon wheelset — and Vittoria Corsa N.EXT TLR 700×30 tires running tubeless-ready, giving the Nitrogen a fast, race-capable setup straight out of the box.

Perfect Control.\" Argon 18 designed the Anti Matter for riders who prioritize speed, efficiency, and control where it matters most: in rough, unpredictable terrain rather than on smooth pavement. This build pairs that frame with a complete SRAM Red AXS XPLR E1 groupset, positioning it as Argon 18's most focused answer to the growing world of competitive gravel racing. Raw Magazine described the Anti Matter's launch as \"an aggressive entry into the increasingly professionalised world of gravel competition\" and called it the fastest gravel bike Argon 18 has ever made.\u003c\/p\u003e\n\u003cp\u003eThe full carbon frame and fork use Argon 18's Pro Level Layup construction, the same tier of carbon engineering the brand applies to its road race bikes, built for riders who don't want to compromise on stiffness or ride quality when the terrain turns rough. The Anti Matter's Gravel Geometry draws directly from Argon 18's endurance road geometry, which itself is derived from its performance road race series — the result is handling and a riding position built around responsiveness rather than long-haul comfort alone. Argon 18 backs this with its Fit System, offering size-specific geometry across the full range so the bike's proportions scale correctly rather than simply stretching one frame size up or down. Tire clearance runs up to 55mm, giving riders room to move up in tire volume as conditions demand.\u003c\/p\u003e\n\u003cp\u003ePower comes from the SRAM Red AXS XPLR E1 groupset, SRAM's wireless, electronic 1x gravel drivetrain built specifically for racing over mixed and rough terrain. The 44t Aero chainring pairs with a 13-speed, 10-46t cassette, giving a wide enough range to cover steep climbs and fast gravel sectors without a front derailleur to manage. The crankset integrates a power meter, and SRAM Red AXS E1 hydraulic disc brakes with 160mm Paceline X rotors handle stopping power on loose surfaces. Underneath, a CeramicSpeed SLT headset and T47 Alpha bottom bracket keep friction low — CeramicSpeed builds these by hand in Denmark with a self-lubricating, corrosion-resistant design and backs them with a lifetime warranty, a detail that matters on a bike meant to spend hours in dust and grit.\u003c\/p\u003e\n\u003cp\u003eZipp's 303 XPLR SW wheelset rounds out the build, a wide-rim wheel Zipp positions as its fastest gravel wheel, designed to integrate seamlessly with wide, tubeless gravel racing tires. Argon 18 spec's the wheels with Schwalbe G-One RS PRO tubeless tires in a 700x45mm size, a fast-rolling race tire with enough volume to handle rougher sectors. Up front, the ATTEN CHB-01 aero handlebar was engineered surface by surface for aerodynamic gains, with an integrated computer mount and a lightweight, one-piece build. The bike also ships with a co-developed ATTEN x Apidura frame bag, built to sit flush with the frame for a clean, aero profile while staying accessible from the saddle — a practical addition for long gravel races or self-supported days that demand on-bike storage without disrupting the riding position. A Repente Quasar CR carbon-railed saddle and an Argon 18 Anti Matter Aero seatpost with 20mm offset complete the cockpit.\u003c\/p\u003e\n\u003cp\u003eThis build is aimed at riders training or racing at a level where every component choice is deliberate — competitive gravel racers, or anyone who wants their gravel bike to ride with the same intent as a road race machine while still handling rough, unpredictable terrain.

Tire clearance runs up to 55mm, giving riders room to size up when a course or trail calls for more volume.\u003c\/p\u003e\n\u003cp\u003eThe SRAM Force AXS XPLR E1 groupset gives this build the same wireless, electronic shifting platform as SRAM's top-tier Red XPLR groupset, built specifically for 1x gravel racing. A 44t Aero chainring pairs with a 13-speed, 10-46t cassette for a wide gear range without a front derailleur to manage, and the crankset integrates a power meter standard. SRAM Force AXS E1 hydraulic disc brakes with 160mm Paceline X rotors provide braking control on loose and mixed surfaces. Underneath, a CeramicSpeed SLT headset and T47 Alpha bottom bracket keep pivot points running smoothly — CeramicSpeed builds these by hand in Denmark with a self-lubricating, corrosion-resistant design and a lifetime warranty, carried over from the range-topping build rather than downgraded for this tier.\u003c\/p\u003e\n\u003cp\u003eZipp's 303 XPLR S wheelset rounds out the build, a wide-rim wheel within Zipp's 303 XPLR gravel platform paired here with Schwalbe G-One RS PRO tubeless tires in a fast-rolling 700x45mm size. Up front, the ATTEN CHB-01 aero handlebar was engineered surface by surface for aerodynamic gains, with an integrated computer mount and a lightweight, one-piece design. The bike ships with a co-developed ATTEN x Apidura frame bag built to sit flush against the frame for a clean profile while staying accessible from the saddle, useful for long gravel races or self-supported days that call for on-bike storage. A Repente Quasar 2.0 saddle and an Argon 18 Anti Matter Aero seatpost with 20mm offset complete the cockpit.\u003c\/p\u003e\n\u003cp\u003eThis build is aimed at riders who want the Anti Matter's race-bred geometry and aero-focused design without paying for Argon 18's absolute top-tier spec. It suits competitive gravel racers and serious weekend racers alike — anyone who wants a bike that rides with road-race intent but handles the rough, unpredictable terrain gravel racing throws at it. The Anti Matter Force AXS XPLR is available in Mystic Dune, Iridium Silver, and Sea Foam \/ Neon.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Argon 18","offers":[{"title":"Mystic Dune \/ XS","offer_id":45841764548652,"sku":"ANT.XS.386A.2E.1","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"Mystic Dune \/ S","offer_id":45841764581420,"sku":"ANT.S.386A.2E.1","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"Mystic Dune \/ M","offer_id":45841764614188,"sku":"ANT.M.386A.2E.1","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"Mystic Dune \/ L","offer_id":45841764646956,"sku":"ANT.L.386A.2E.1","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"Mystic Dune \/ XL","offer_id":45841764679724,"sku":"ANT.XL.386A.2E.1","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"Iridium Silver \/ XS","offer_id":45841764712492,"sku":"ANT.XS.386B.2E.1","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"Iridium Silver \/ S","offer_id":45841764745260,"sku":"ANT.S.386B.2E.1","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"Iridium Silver \/ M","offer_id":45841764778028,"sku":"ANT.M.386B.2E.1","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"Iridium Silver \/ L","offer_id":45841764810796,"sku":"ANT.L.386B.2E.1","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"Iridium Silver \/ XL","offer_id":45841764843564,"sku":"ANT.XL.386B.2E.1","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"Sea Foam \/ Neon \/ XS","offer_id":45841764876332,"sku":"ANT.XS.386C.2E.1","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"Sea Foam \/ Neon \/ S","offer_id":45841764909100,"sku":"ANT.S.386C.2E.1","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"Sea Foam \/ Neon \/ M","offer_id":45841764941868,"sku":"ANT.M.386C.2E.1","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"Sea Foam \/ Neon \/ L","offer_id":45841764974636,"sku":"ANT.L.386C.2E.1","price":8999.0,"currency_code":"USD","in_stock":true},{"title":"Sea Foam \/ Neon \/ XL","offer_id":45841765007404,"sku":"ANT.XL.386C.2E.1","price":8999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/ARGON-18-ANTI-MATTER-FORCE-XPLR-AXS-E1-2026-MYSTIC-DUNE_da6eb9d0-aa85-46df-bb88-162f385c2250.jpg?v=1784910781"},{"product_id":"argon-18-anti-matter-rival-axs-xplr-bike-6202","title":"Argon 18 Anti Matter Rival AXS XPLR Bike","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003eArgon 18 Anti Matter Rival AXS XPLR Bike\u003c\/strong\u003e is the entry point into Argon 18's Anti Matter platform, the brand's dedicated race gravel bike built around the idea of \"Pure Energy. Perfect Control.\" Argon 18 designed the Anti Matter for riders who prioritize speed, efficiency, and control on rough, unpredictable terrain rather than smooth pavement, and this build carries that same frame and geometry with a SRAM Rival AXS XPLR E1 groupset, putting Argon 18's race gravel platform at its most accessible price point. Raw Magazine called the Anti Matter platform \"the fastest gravel bike Argon 18 has ever made\" when describing its launch as an aggressive entry into competitive gravel racing.\u003c\/p\u003e\n\u003cp\u003eThe full carbon frame and fork use Argon 18's Pro Level Layup construction, the same carbon engineering tier the brand applies across its road race bikes, so stepping into the Rival build doesn't mean stepping down in frame quality. The Anti Matter's Gravel Geometry is derived from Argon 18's endurance road geometry, itself pulled from the brand's performance road race series, giving the bike a riding position built around handling and responsiveness rather than long-haul comfort alone. Argon 18's Fit System gives each frame size its own geometry rather than simply scaling one frame up or down, so fit stays consistent whether you're on an XS or an XL. Tire clearance runs up to 55mm, leaving room to size up when the terrain calls for it.\u003c\/p\u003e\n\u003cp\u003eThe SRAM Rival AXS XPLR E1 groupset brings wireless, electronic shifting to this build, still built specifically for 1x gravel racing. A 40t chainring pairs with a 13-speed, 10-46t cassette, giving a wide gear range without a front derailleur, though the Rival-level crankset doesn't come with the integrated power meter found on the Force and Red builds higher in the range. SRAM Rival AXS E1 hydraulic disc brakes with 160mm Paceline X rotors handle stopping power on loose surfaces. A CeramicSpeed SLT headset keeps steering smooth — the same premium bearing carried across every Anti Matter build — while a standard SRAM DUB T47 bottom bracket takes the place of the CeramicSpeed unit found on the pricier builds.\u003c\/p\u003e\n\u003cp\u003eDT Swiss G1800 wheels round out the build, paired with Schwalbe G-One RS PRO tubeless tires in a fast-rolling 700x45mm size, the same tire spec used across the entire Anti Matter range. Up front, the ATTEN CHB-01 aero handlebar was engineered surface by surface for aerodynamic gains, with an integrated computer mount and a lightweight, one-piece design shared with every other Anti Matter build. The bike ships with a co-developed ATTEN x Apidura frame bag built to sit flush against the frame for a clean profile while staying accessible from the saddle, useful for long gravel days that call for on-bike storage. A Repente Quasar S 2.0 saddle and an Argon 18 Anti Matter Aero seatpost with 20mm offset complete the cockpit.\u003c\/p\u003e\n\u003cp\u003eThis build is for riders who want the Anti Matter's race-bred frame and aero-focused design without paying for a fully loaded groupset and premium wheelset. It's a strong entry point for someone getting into gravel racing, or an experienced rider who plans to upgrade wheels and components over time while keeping a frame that's already race-capable.
