A BIKE FOR THE WAY RIDERS RIDE Caledonia doesn't fit in a box nicely, and we like it that way. It was conceived on our Thursday night rides-routes that often play fast and loose with 'road ride.' As we tried to stuff bigger tires into our R5s and streamline our Asperos, a new kind of bike was born. When we design a bike, we start with our library of tube shapes. These shapes are tubes we've used on other models that we know to have various qualities-aerodynamic, stiff, ultralight, etc.-and they help get us to the refinement stage on a bike more quickly. In the case of Caledonia, we wanted durability, lightweight, and aerodynamics to be in balance and selected a package that achieved the performance demands of this kind of race bike. Caledonia uses a standard round bar, stem, and seat post, giving riders the option to build their ultimate ride without compromise. Integrated accessory mounts and hidden fender mounts keep the bike's refined lines so you can ride with lights and computers in a downpour and still look fast. Because we all know if it looks fast, it probably is. Rather than designing multiple versions of the bike with various fit profiles (R5, R-Series, etc.) like we've done in the past, we designed a system that enables a broad range of fits on a single bike while maintaining the aesthetic and functional cleanliness we demand. Modern road riders are looking for bikes to handle long-distance, high pace, no limits, and offer maximum fun. By placing lower modulus carbon in key areas to mitigate the brittleness of hi-mod fiber-the Caledonia delivers performance, comfort, and speed. Oh, and you can fit a 34mm tire in there. Or 31mm with fenders.

Our engineers like to joke that, "if it looks fast, it probably is." But there's some truth to that, and Áspero-5 looks fast standing still. No cables in the wind, tube shapes from our aerodynamically-proven library, and a hint of a cut-out in the seat tube, all add up to a bike that proves the adage. - Lightweight Speed Some might say aero doesn't matter on a gravel bike, but if you've battled a headwind across an open prairie, the thirty-two grams of drag you'll save with the Áspero-5 come as a welcome respite. Most gravel racing is done without the benefit of a World Tour peloton—or World Tour tactics—and when it's your nose in the wind all day, it's nice to know your bike's shouldering a bit of the load. - Two-Position Adjustment Trail—front-wheel response to rider input—is the most critical factor in high-velocity handling. Flipping the two-position "Trail Mixer" to compensate for the difference in circumference between a 650b and 700c tire maintains consistent handling by maintaining consistent trail figures. - Multiple Configurations We designed Aspero with clearance for up to 700c x 40mm tires or 650b x 49mm tires. Of course, there are variables—rim width, tire casing, and tread depth—which will affect final clearance. We (and the International Organization for Standardization, or ISO), always recommend 4mm of clearance between the tire and frame. **New Shimano road (not gravel) 12-speed front derailleurs reduce tire clearance in the rear of the frame to 700 x 38c or 650b x 45c. - SRAM Integrated Power Red and Force build 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.

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 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 equality. 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 Cervelo 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, but 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. - 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. - 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. - 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 400 mm-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.

The S5 prioritizes aerodynamic performance and stiffness, making it a platform preferred by the fastest sprinters in the world. You've no doubt noticed the now-iconic V-Stem. We optimized that shape to deliver the best possible performance in the wind, hid the cables inside, and made enough bar/stem/stack options to fit just about anyone. It'll clear 28mm tires, too so you can eke out even more aero advantage.
