Cervelo Bicycles

Faster Than the Rest The all-new Áspero-5 was built for the front end of the race, and is the most aerodynamic gravel bike ever created. Cervélo has long been synonymous with aerodynamic performance, and we’ve brought that 30 years of expertise to gravel racing. The new bike is a stunning 37 Watts faster than the outgoing model, and 34 Watts faster than its nearest competitor. With clearance for 45mm tires, downtube storage, and a threaded bottom bracket, Áspero-5 is ready to race the second it rolls off the shop floor. It made its rainbow-jersey debut (and won!) under UCI Gravel World Champion Marianne Vos, and will be campaigned by some of the most elite bike racers in the world. SHAPE OF SPEED Áspero-5 is 37 Watts faster than its predecessor, and 34 Watts faster than the nearest competitor. Cervélo has long led the industry in aerodynamics, and we’ve delivered a gravel race bike worthy of that reputation. The aero handlebar and stem are responsible for nearly 6 Watts of that savings on their own. WEIGHT The new Áspero-5 is 66 grams lighter than its predecessor, despite adding a significant amount of surface area to improve aerodynamic performance. MIXED & MATCHED TIRE GEO When fitted with equally-sized tires (e.g. 42mm front and rear), Áspero-5’s handling is stable, confidence-inspiring, and ready for the roughest courses. To increase aerodynamics even further, and sharpen handling for less-technical courses, we optimized the geo for a 4mm tire width differential (e.g. 40mm front, 44mm rear). DOWNTUBE STORAGE First seen on the P-Series triathlon bike, we’ve implemented our industry-leading downtube storage door on the Áspero-5. It’s the lightest and most aerodynamically efficient system on the market, and puts a tube, tools, and a flat kit inside the frame and out of the wind.

THE FASTEST BIKE OF THE MODERN ERA The S5 has one job—get to the line before everyone else. Under the likes of Wout van Aert, Marianne Vos, and Christophe LaPorte, the new model has already proven itself as a tool without equal. In the 2022 Tour de France, this bike propelled Wout to the highest ever Points Classification score of the modern era. At 480, Wout was some 194 points ahead of his nearest rival—tangible proof that Cervélo keeps delivering aerodynamic gains to our World Tour athletes. The new S5 has reduced drag by 65 grams, and increased the frame’s surface area while still reducing overall weight. The deeper frame sections maximize the shapes allowed by the UCI. Meanwhile the iconic V-stem has been further refined and a new fork designed to simplify the entire front end. What’s more, a ground-breaking new wheel design concept has been co-developed with Reserve to increase stability and reduce drag in turbulent aero conditions. V IS FOR VELOCITY In pursuit of speed, everyone wants to try different positions to find their most aggressive fit. The S5's iconic V-stem not only inspires confident handling at high speeds, it's now also remarkably simple to dial in your perfect set-up. All the necessary spacers come with the bike, and there’s now only one bolt length, reducing complexity and making the system 53g lighter in the process. TIRE CLEARANCE Wider wheels and tires are faster aerodynamically, and more comfortable to boot. S5 comes specced with 28mm tires but has clearance for up to a 34mm (measured) tire. The frame is optimized to complement the wider Reserve 52/63 turbulent aero wheels. In addition to the handling benefits, this saves over 5 watts compared to the previous Reserve wheelset. FRAME ENHANCEMENTS The UCI’s new regulations on aerodynamic design allowed us some additional room to deepen our aero profiles and squeeze 65 more grams of drag performance out of what is already the fastest aero bike on the market. You’ll notice a deeper head tube and BB area, and more aggressive shaping on the trailing edges of the tubes. Since the new S5 is only compatible with electronic shifting, we were able to tidy the dropout a bit and update the shaping all over the bike. HANDLEBAR REFINEMENT We’ve improved the comfort of the handlebar and tweaked the shape to get a perfectly flat bar-to-hood transition. We now use a two-bolt interface that allows for infinite tilt adjustments between 0 and 5 degrees. KEEPING IT SIMPLE Bike fitters at every level are moving away from longer-offset seat posts, and the new S5 comes stock with a 15mm offset post on most sizes (vs 25mm offset on outgoing S5). The old seat posts are forward-compatible, and we’ll keep the 400mm-long, 25mm offset post in stock for those looking for a more extreme fit. SRAM INTEGRATED POWER Red and Force builds include Quarq Zero power meters integrated into the crank. The integration of a power meter results in better stiffness, lighter weight, and improved accuracy over aftermarket solutions—and the DZero delivers power measurement accurate to +/- 1.5%, even in variable temperatures. SORRY CAMPY FANS The 2022 S5 Disc frameset is designed to accommodate electronic shifting groupsets that use connectors up to 6mm in diameter, therefore Campagnolo EPS is not compatible with this frameset. Mechanical shifting groupsets are also not compatible with this frameset.

Take one look at the all-new P-Series, and you’ll notice a striking resemblance to our flagship TT bike, the P5. P-Series benefits from all the racing, wind tunnel time, and testing required to make the P5 the fastest TT bike in the World Tour, but adds a couple features that make it a perfect companion for a triathlon of any distance

Haul Ass, Not Cargo In 2019, Áspero took the gravel world by storm, heralding a “new era of speed in gravel.” Fun, but flat out. The new Áspero remains true to its original brief, but with some improvements: a threaded BB shell, neater cable routing, and a UDH-compatible derailleur hanger for those who want to use SRAM’s Transmission drivetrains. And it’s more aero, of course. In the case of Áspero, aerodynamic performance is less about pure speed as a result of drag reduction, and more about conservation of energy. After a big day in a headwind, the three watts saved over the previous Aspero might add up to one less energy gel your stomach has to digest—WORTH IT. In addition to the drag reduction, we also dropped the seat stays to give a bit more compliance out back, and reduced front-end stiffness slightly to make the last hours of a long race less painful. Between those dropped seat stays, we added in a bit more clearance for mud, too, taking what we learned from R5-CX (and the Unbound mudfest in 2023). It’s a lot of seemingly small improvements, but they add up to a lot. The result is a bike that feels a lot like the original Áspero, but is faster, more comfortable, and more versatile.

DESCENDED FROM GREATNESS Take one look at the all-new P-Series, and you’ll notice a striking resemblance to our flagship TT bike, the P5. P-Series benefits from all the racing, wind tunnel time, and testing required to make the P5 the fastest TT bike in the World Tour, but adds a couple features that make it a perfect companion for a triathlon of any distance. P-Series uses a fork with a D-shaped steerer tube and round stem interface. This means you can use whichever basebar and extensions you prefer, and make changes if your fit or preference changes. It’s also significantly more adaptable if you have very specific fit requirements. Increased wheel and tire clearance, reduced aerodynamic drag, neater cable routing, and Cervelo’s first internal frame storage all add up to create the bike of choice for those looking to make the most of the time between T1 and T2. FREE SPEED The new P-Series frame is 5.9 grams faster than the outgoing one, but the added tire clearance makes room for the Reserve 52/63 wheels, and 29mm Vittoria tires, which combine for a 30 grams or 3.5 watts savings vs the Reserve 50/Vittoria 28 combo. IN-FRAME STORAGE New this year on the P-Series, the in-frame storage is designed for a tube, small multi-tool, and a CO2 canister. The hatch is easily removable with or without a bottle in place—just flip the lock and pull. FUEL FOR THE RUN In addition to the all-new in-frame storage, we still ship every P-Series with the Smartpak 400, our top tube-mounted bento box, which makes fueling on the bike much simpler without sacrificing aerodynamics. FIT FOR SPEED The P-Series is all about adapting to the athlete. Maximum stack increased to 53mm, and we include spacers to bring the basebar up that high. Fitting and positions are evolving, and P-Series offers the most flexibility in an incredibly fast package.

THREADED BOTTOM BRACKET Aspero uses the asymmetrical T47a threaded bottom bracket we pioneered on R5-CX. It’s a simple, rider-serviceable interface that allows us to deliver the benefits of BBRight in a more user-friendly form. UNIVERSAL DERAILLEUR HANGAR We used SRAM’s Universal Derailleur Hanger (UDH) standard on the new Aspero. It’s ideal if you want to live your best ‘business in the front, party in the back’ life with one of SRAM’s Transmission drivetrains today, and ensures compatibility for future drivetrain developments. INTERNAL CABLE ROUTING Aspero shares the same bearing dimensions as R5, Soloist, R5-CX, and Caledonia, which means you can use any combination of bearing caps and stems.
