The numbers are specific: 37 Watts faster than the outgoing Aspero, 34 Watts faster than the nearest competitor, with nearly 6 of those Watts coming from the integrated aero cockpit alone. That performance showed up where it counts: the Aspero-5 made its competition debut under UCI Gravel World Champion Marianne Vos, who won in it.\u003c\/p\u003e\n\u003cp\u003eBeyond the aero story, the bike is built to race: 45mm tire clearance, downtube storage, a threaded bottom bracket, and a direct-mount top tube bag attachment. Carbon handlebar, stem, and seatpost are included on every build. At RA Cycles, the Aspero-5 is available in GRX Di2, Force AXS, Force XPLR AXS, and Red XPLR eTap AXS builds across six frame sizes.\u003c\/p\u003e\n\u003c\/div\u003e","products":[{"product_id":"cervelo-aspero-5-force-axs-bike","title":"Cervelo Aspero-5 Force AXS Bike","description":"\u003cdiv\u003e\n\u003cp\u003eCervelo has built its reputation on one principle: make riders faster. Over 30 years, that obsession with aerodynamic engineering won Tour de France stages, world championships, and Olympic medals on the road. The \u003cstrong\u003eCervelo Aspero-5 Force AXS Bike\u003c\/strong\u003e applies that same methodology to gravel racing — and the results are measurable. By Cervelo's testing, the Aspero-5 is 37 watts faster than its predecessor and 34 watts faster than its nearest competitor. The bike debuted under UCI Gravel World Champion Marianne Vos, who put it on the top step of the podium immediately. This is what it looks like when a road aero engineering program turns its full attention to gravel racing.\u003c\/p\u003e\n\u003cp\u003eThe frame achieves something worth noting: despite expanded aero tube profiles and greater surface area, the Aspero-5 carbon frame is 66 grams lighter than the previous generation. The carbon construction is tuned for the dual demands of competitive gravel — stiff enough for powerful sprinting, compliant enough for sustained off-road vibration. Clearance runs to 45mm tires, and the T47 BBright threaded bottom bracket interface provides long-term serviceability without press-fit complications. The most distinctly Cervelo feature on the frame is the integrated downtube storage system, adapted directly from the P-Series triathlon platform. Two storage rolls — one for a flat kit, one for a spare tube — fit inside the downtube, completely sealed from the wind. It's the lightest and most aerodynamically efficient onboard storage solution on a gravel race bike, and it ships ready to use.\u003c\/p\u003e\n\u003cp\u003eThe Cervelo HB16 Carbon handlebar and ST31 Carbon stem aren't just spec choices — they account for nearly 6 watts of the bike's total aero advantage on their own. The integrated carbon cockpit manages cable routing internally, presenting the cleanest possible front profile. Cervelo's geometry is built to exploit the Aspero-5's mixed-width wheel approach: a 40mm front tire for reduced frontal area and sharper handling response, paired with a 44mm rear for traction and compliance over rough terrain. The Reserve 40|44TA GR wheelset is spec'd precisely for this setup. The two rim widths are different products — not just different tire sizes on the same rim — because the optimal aerodynamic profile for each position differs. Chainstays hold at 422.5mm across all six sizes, giving the bike a consistently tight, responsive rear end regardless of frame size.\u003c\/p\u003e\n\u003cp\u003eThe Reserve 40|44TA GR wheelset is built through Cervelo's Turbulent Aero program, developed using real-world wind data to optimize for the variable crosswinds and gusty conditions of actual gravel race courses rather than controlled tunnel conditions. Both wheels are hookless, tubeless compatible, and laced to DT Swiss 350 hubs — a hub that balances weight, durability, and serviceability better than most. The Vittoria Corsa Pro Control TLR G2.0 700x42 tires run tubeless and bring road-race precision to off-road terrain.\u003c\/p\u003e\n\u003cp\u003eThe drivetrain is Cervelo's Force AXS E1 build specification, which layers SRAM components across tiers in deliberate ways. The SRAM Force 1 AXS E1 DUB WIDE crankset includes a factory-integrated power meter spinning a 48T aero chainring — the same hardware found on bikes at significantly higher price points — on a SRAM DUB WIDE Ceramic bearing over a T47 BBright bottom bracket shell. SRAM Force AXS E1 levers feed a SRAM X0 Eagle AXS T-Type rear derailleur, giving you X0's superior derailleur durability and performance within a Force-level build. The SRAM X0 Eagle T-Type 10-52T cassette delivers 522% range: enough for steep climbs without sacrificing top-end gearing on flat open sections. SRAM Force AXS E1 hydraulic disc brakes with SRAM Paceline Centerlock rotors handle stopping, and the entire system is wireless — no cables, no friction points, no in-season adjustment required.\u003c\/p\u003e\n\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e37-watt aero advantage:\u003c\/strong\u003e Cervelo's aerodynamic tube shapes, integrated cockpit, and refined carbon construction deliver a measurable speed gain over the previous Aspero and the nearest competitor — verified through Cervelo's testing program.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated downtube storage:\u003c\/strong\u003e Adapted from the P-Series triathlon platform, the built-in storage system keeps flat kit and a spare tube aerodynamically sealed inside the frame — ready to race without adding wind drag.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMixed 40\/44mm wheel geometry:\u003c\/strong\u003e The Reserve 40|44TA GR wheelset pairs a narrower front rim for reduced frontal area and steering response with a wider rear rim for grip and compliance — spec'd to match Cervelo's geometry intent.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated power meter:\u003c\/strong\u003e The SRAM Force 1 AXS E1 crankset includes a factory-built power meter at no extra cost — the same data quality found on significantly higher-spec builds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eX0 Eagle rear derailleur:\u003c\/strong\u003e SRAM's X0 Eagle T-Type delivers superior shift performance and mud-condition reliability compared to Force-tier derailleurs, spec'd here as a deliberate upgrade within the build.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003eFinal Take\u003c\/h3\u003e\n\u003cp\u003eThe Cervelo Aspero-5 Force AXS is a gravel race bike in the truest sense — designed for front-of-pack speed on fast, competitive gravel terrain.

The Aspero-5 is 37 watts faster than its predecessor and 34 watts faster than the nearest competitor, figures validated through the same wind tunnel and real-world testing process that has made Cervelo synonymous with aero performance in professional road cycling. The bike made its racing debut under UCI Gravel World Champion Marianne Vos, who won in it — a statement of intent that Cervelo backed up with engineering. Despite the expanded surface area required to achieve those aerodynamic gains, the Aspero-5 carbon frame is 66 grams lighter than the outgoing model. The integrated carbon cockpit — Cervelo ST31 stem and HB16 carbon handlebar — contributes nearly 6 of those total watt savings on its own.\u003c\/p\u003e\n\u003cp\u003eThe frameset accommodates tires up to 45mm, and Cervelo has optimized the geometry for both matched and mixed-width tire configurations. This build ships with Vittoria Corsa Pro Control TLR G2.0 at 700x42, and the Reserve 40|44TA GR wheelset — 40mm front, 44mm rear — pairs improved aerodynamics on the leading edge with added traction and stability at the back. That asymmetric setup is deliberate: Cervelo has validated it for technical gravel racing where the front tire's job and the rear tire's job are genuinely different. Integrated downtube storage, adapted directly from Cervelo's P-Series triathlon platform, houses tools and flat kit inside the frame and out of the wind — the lightest and most aerodynamic storage solution the brand has produced. The T47 BBright threaded bottom bracket with a SRAM DUB Wide Ceramic insert rounds out a frame that arrives configured for race day without further modification.\u003c\/p\u003e\n\u003cp\u003eThe Red AXS 1 build centers on a SRAM Red 1 AXS E1 DUB Wide crankset with integrated power meter, spinning a 48T aero chainring through a SRAM XX SL Eagle AXS T-Type rear derailleur and 10-52T cassette — the same Eagle T-Type system at the top of SRAM's off-road wireless lineup, here applied to gravel racing. SRAM Red AXS E1 hydraulic disc brakes with SRAM Paceline X Centerlock rotors handle braking. The Reserve 40|44TA GR wheels roll on DT Swiss 240 hubs front and rear, tubeless-ready and set up for the Vittoria rubber at 700x42. The build also includes a Hammerhead Karoo 3 GPS computer, two Arundel Mandible matte UD carbon bottle cages, Cervelo's front computer and rear accessory mounts, a Cervelo Smartpak top tube storage bag, and in-frame storage rolls for tube and flat kit — a complete race setup out of the box.\u003c\/p\u003e\n\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eAero Engineering From Cervelo's Road and Triathlon DNA\u003c\/strong\u003e — Cervelo's reputation in aerodynamics was built on road and time trial bikes raced at the highest level of the sport, and the Aspero-5 represents the first time that full body of expertise has been applied to a gravel frame without compromise. The 37-watt improvement over the outgoing Aspero and 34-watt advantage over the closest competitor are meaningful at race pace — the kind of gaps that change the calculus of a long gravel race. The integrated carbon cockpit accounts for nearly 6 watts of that saving on its own. The downtube storage system, adapted from the P-Series triathlon platform, keeps tools and flat kit tucked inside the frame and out of the wind. The bike is 66 grams lighter than its predecessor despite the increased surface area — gains that required engineering, not compromise.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSRAM Red 1 AXS and XX SL Eagle T-Type — The Top of the Wireless Gravel Drivetrain\u003c\/strong\u003e — The Red AXS 1 build uses SRAM's best electronic gravel hardware across the board. The Red 1 AXS E1 crankset with integrated dual-sided power meter means you have accurate watt data from the moment you roll out. The XX SL Eagle AXS T-Type rear derailleur is SRAM's flagship off-road wireless unit — cable-free, clutchless, and precise across the 10-52T range. The 48T aero chainring is a single-ring gravel setup built for efficiency at higher cadences on fast terrain, with enough gear range via the 10-52T cassette to handle the climbs that show up between the fast parts. SRAM Red AXS E1 hydraulic disc brakes deliver the modulation and power confidence that gravel racing demands.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReserve 40|44TA GR Wheels and the Mixed-Width Setup\u003c\/strong\u003e — The Reserve 40|44TA GR wheelset is built specifically for gravel racing — 40mm front, 44mm rear — with DT Swiss 240 hubs at both ends. The asymmetric depth and width is purpose-designed: the narrower front wheel improves aerodynamics where the leading edge matters most, while the wider rear provides additional volume and traction where the ground contact patch is doing the work. Reserve's Turbulent Aero development program, which Cervelo has supported, uses real-world wind data rather than tunnel-only optimization — a distinction that produces wheels that perform well in the variable conditions of actual gravel racing.

Whether or not a rider ever measures the exact number, the shaping is deliberate: the front end, cockpit, and tube profiles are all cut to reduce drag on fast, open gravel roads.\u003c\/p\u003e\n\n\u003cp\u003eRace-day practicality carries over from the rest of the Áspero-5 lineup. The frame clears up to 45mm tires, and this build ships with 42mm Vittoria Corsa Pro Control tubeless tires mounted. Cervélo built downtube and top tube storage into the frame, and this build includes in-frame storage rolls for a flat kit and spare tube, a Smartpak top tube bag, front and rear accessory mounts, and two Arundel Mandible carbon bottle cages. The bottom bracket is a threaded T47 design rather than a press-fit unit, which matters to anyone who's dealt with a press-fit BB creaking after a wet, muddy race.\u003c\/p\u003e\n\n\u003cp\u003eThe drivetrain is a mullet setup, same as the rest of the Áspero-5 electronic builds: SRAM Force AXS E1 shifters and hydraulic disc brakes on Paceline Centerlock rotors, paired with a single 48T aero chainring and SRAM's X0 Eagle AXS T-Type mountain bike rear derailleur. That derailleur runs a wide-range 10-52 cassette, giving this build the same low-end climbing gear as the more expensive Red AXS version while holding a usable top gear on flat, fast sectors. The crank carries a built-in power meter on a ceramic DUB WIDE bottom bracket. Reserve 48\/53 GR wheels handle the rolling stock here, built on DT Swiss 350 hubs rather than the higher-end 240 hubs on the Red AXS build, and a Fizik Vento Argo X3 saddle finishes out the contact points.\u003c\/p\u003e\n\n\u003cp\u003eCervélo has raced this platform at the top level, debuting it under Marianne Vos at the UCI Gravel World Championships, where she won wearing the rainbow jersey. This build is available in Five Black across six frame sizes from 48cm to 61cm. For a rider who wants the race-bred speed and storage of the Áspero-5 platform without paying for Red AXS, the Force AXS 1 build delivers the same core bike at a more accessible price.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Cervelo","offers":[{"title":"Five Black \/ 48cm","offer_id":45780109983788,"sku":"0M0ALBFE1C48","price":9000.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 51cm","offer_id":45780110016556,"sku":"0M0ALBFE1C51","price":9000.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 54cm","offer_id":45780110049324,"sku":"0M0ALBFE1C54","price":9000.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 56cm","offer_id":45780110082092,"sku":"0M0ALBFE1C56","price":9000.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 58cm","offer_id":45780110114860,"sku":"0M0ALBFE1C58","price":9000.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 61cm","offer_id":45780110147628,"sku":"0M0ALBFE1C61","price":9000.0,"currency_code":"USD","in_stock":true},{"title":"Digital Moss \/ 48cm","offer_id":45780110180396,"sku":"0M0ALBFE2C48","price":9000.0,"currency_code":"USD","in_stock":true},{"title":"Digital Moss \/ 51cm","offer_id":45780110213164,"sku":"0M0ALBFE2C51","price":9000.0,"currency_code":"USD","in_stock":true},{"title":"Digital Moss \/ 54cm","offer_id":45780110245932,"sku":"0M0ALBFE2C54","price":9000.0,"currency_code":"USD","in_stock":true},{"title":"Digital Moss \/ 56cm","offer_id":45780110278700,"sku":"0M0ALBFE2C56","price":9000.0,"currency_code":"USD","in_stock":true},{"title":"Digital Moss \/ 58cm","offer_id":45780110311468,"sku":"0M0ALBFE2C58","price":9000.0,"currency_code":"USD","in_stock":true},{"title":"Digital Moss \/ 61cm","offer_id":45780110344236,"sku":"0M0ALBFE2C61","price":9000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/CERVELO-ASPERO-5-FORCE-AXS-1-2027-FIVE-BLACK_d419a3bd-9da8-41df-b907-c42a1de1194a.jpg?v=1783545214"},{"product_id":"cervelo-aspero-5-grx-di2-1-bike-7202","title":"Cervelo Aspero-5 GRX Di2 1 Bike","description":"\u003cdiv\u003e\n\u003cp\u003e\u003cstrong\u003eCervelo Aspero-5 GRX Di2 1 Bike\u003c\/strong\u003e is Cervelo's aero gravel race bike, built by a company that's spent decades leading road aerodynamics and pointed that same expertise at gravel racing. Cervelo says the Aspero-5 is 37 watts faster than its predecessor and 34 watts faster than its nearest competitor, with the aero handlebar and stem alone accounting for roughly 6 watts of that. The bike made its race debut under UCI Gravel World Champion Marianne Vos, who won the rainbow jersey on it. This build pairs the Aspero-5 frame with Shimano's wireless GRX Di2 groupset, priced at $8,850.\u003c\/p\u003e\n\u003cp\u003eThe frame carries Cervelo's aero shaping down into details that matter for gravel racing specifically: clearance for 45mm tires, downtube storage for tools or a flat kit, and a threaded T47 bottom bracket rather than a press-fit design that can creak or wear over a season of rough roads. Cervelo built the Aspero-5 to line up on the start line ready to race, and the frame reflects that — this isn't a bikepacking rig with rack mounts bolted on, it's a race bike that happens to run wide tires and long distances well.\u003c\/p\u003e\n\u003cp\u003eThe drivetrain runs Shimano's GRX Di2 electronic shifting through a single Wolf Tooth 48t Aero chainring on a GRX crank with an integrated 4iiii power meter, paired with a Shimano XTR 10-51, 12-speed cassette — a mountain bike cassette rather than a gravel-specific one, giving this build a wider gear range than a standard 1x gravel setup while keeping the shifting and brake feel of Shimano's gravel-specific levers. A Ceramic Speed SL bottom bracket keeps friction low, and GRX hydraulic disc brakes on Centerlock rotors provide consistent stopping power across loose and wet gravel surfaces where braking traction changes constantly.\u003c\/p\u003e\n\u003cp\u003eWheels are Reserve's 48mm front and 53mm rear GR wheelset, a gravel-specific aero profile built on DT Swiss 350 hubs and tubeless compatible, wrapped in Vittoria Corsa Pro Control tires in a 700x42 tubeless width that takes advantage of the frame's tire clearance without maxing it out. Cervelo's own carbon handlebar, stem, and seatpost keep the front end in line with the aero intent of the rest of the bike, and a Fizik Vento Argo X3 saddle rounds out a race-oriented riding position rather than a relaxed all-day setup.\u003c\/p\u003e\n\u003cp\u003eStorage comes built into the spec rather than bolted on afterward: in-frame storage rolls for a flat kit and inner tube, a Cervelo Smartpak top tube bag, and front and rear accessory mounts, along with two Arundel carbon bottle cages for long stages between aid stations. This is a bike for a rider racing gravel events who wants aero performance without giving up the tire clearance and durability gravel racing demands.

At $12,650, it sits at the top of the Áspero-5 range, and Cervélo built this generation specifically for gravel racing rather than casual dirt-road riding.\u003c\/p\u003e\n\n\u003cp\u003eCervélo describes the new Áspero-5 as the most aerodynamic gravel bike it has built, drawing on the aero development the brand has applied to its road bikes for decades. Cervélo says this generation is 37 watts faster than the outgoing Áspero and 34 watts faster than its nearest competitor, with the aero handlebar and stem alone accounting for nearly 6 watts of that savings. Whatever the exact number on a given day, the intent is clear in the shaping: the front end, cockpit, and tube profiles are all cut for speed on open, fast gravel roads, not just styled to look aggressive.\u003c\/p\u003e\n\n\u003cp\u003eThat speed focus doesn't come at the expense of usability on race day. The frame clears up to 45mm tires, well into the range gravel racers actually run on rough terrain, and this build ships with 42mm Vittoria Corsa Pro Control tubeless tires already mounted. Cervélo also built in downtube and top tube storage, and this build comes with Cervélo's in-frame storage rolls for a flat kit and spare tube, plus a Smartpak top tube bag, front and rear accessory mounts, and two Arundel Mandible carbon bottle cages. The bottom bracket is a threaded T47 design rather than a press-fit unit, a detail gravel riders who've dealt with creaking press-fit bottom brackets on rough terrain will appreciate. Cervélo's stated goal with this build is a bike that's ready to race the moment it leaves the shop, and the combination of tire clearance, storage, and race-ready gearing backs that up.\u003c\/p\u003e\n\n\u003cp\u003eThe drivetrain is where this build gets interesting: it's a mullet setup, pairing SRAM Red AXS E1 shifters and hydraulic disc brakes with a single 48T aero-shaped chainring and SRAM's XX SL Eagle AXS T-Type mountain bike rear derailleur. That derailleur runs a wide-range 10-52 cassette, giving this Áspero-5 far more low-end climbing gear than a standard 2x road cassette while still holding a usable top gear for fast, flat gravel sectors. The crank carries a built-in power meter and mounts to a ceramic DUB WIDE bottom bracket. Reserve 48\/53 GR wheels, built specifically for gravel and mounted on DT Swiss 240 hubs, complete the rolling stock, and a Fizik Vento Argo X1 saddle finishes out the build.\u003c\/p\u003e\n\n\u003cp\u003eCervélo points to results as validation for this platform: the Áspero-5 made its race debut under Marianne Vos at the UCI Gravel World Championships, where she won wearing the rainbow jersey, and Cervélo continues to race this platform with some of the sport's top gravel racers. This build is available in Five Black across six frame sizes from 48cm to 61cm. For a rider training for or racing long, fast gravel events, where climbing gears and flat-out speed both matter, the Áspero-5 Red AXS 1 is built around exactly that demand.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Cervelo","offers":[{"title":"Five Black \/ 48cm","offer_id":45784426446892,"sku":"0M0ALBRE1C48","price":12650.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 51cm","offer_id":45784426479660,"sku":"0M0ALBRE1C51","price":12650.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 54cm","offer_id":45784426512428,"sku":"0M0ALBRE1C54","price":12650.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 56cm","offer_id":45784426545196,"sku":"0M0ALBRE1C56","price":12650.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 58cm","offer_id":45784426577964,"sku":"0M0ALBRE1C58","price":12650.0,"currency_code":"USD","in_stock":true},{"title":"Five Black \/ 61cm","offer_id":45784426610732,"sku":"0M0ALBRE1C61","price":12650.0,"currency_code":"USD","in_stock":true},{"title":"Digital Moss \/ 48cm","offer_id":45784426643500,"sku":"0M0ALBRE2C48","price":12650.0,"currency_code":"USD","in_stock":true},{"title":"Digital Moss \/ 51cm","offer_id":45784426676268,"sku":"0M0ALBRE2C51","price":12650.0,"currency_code":"USD","in_stock":true},{"title":"Digital Moss \/ 54cm","offer_id":45784426709036,"sku":"0M0ALBRE2C54","price":12650.0,"currency_code":"USD","in_stock":true},{"title":"Digital Moss \/ 56cm","offer_id":45784426741804,"sku":"0M0ALBRE2C56","price":12650.0,"currency_code":"USD","in_stock":true},{"title":"Digital Moss \/ 58cm","offer_id":45784426774572,"sku":"0M0ALBRE2C58","price":12650.0,"currency_code":"USD","in_stock":true},{"title":"Digital Moss \/ 61cm","offer_id":45784426807340,"sku":"0M0ALBRE2C61","price":12650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/CERVELO-ASPERO-5-RED-AXS-1-2027-FIVE-BLACK_4a163762-1e7b-4167-9124-4b499bb78dd1.jpg?v=1783613098"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/collections\/Cervelo-Aspero-5.jpg?v=1737730812","url":"https:\/\/ricycles.com\/collections\/cervelo-aspero-5.oembed","provider":"RA Cycles","version":"1.0","type":"link"}
