Cervelo Bikes

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.

WHAT GOES UP MUST COME DOWN R5 has one job—get to the top, fast. But for all the glory and fanfare that comes with a summit finish, they're rarely the only climb of the day. And while a race isn't usually won on a descent, they can certainly be lost. A climbing bike that can't carve a hairpin is a bit like a cup of decaf coffee. This is the fourth iteration of the R5, and while weight and stiffness have varied over the years, the handling, poise, and unmatched prowess on a descent have been consistent since day one.

Flat Out. That's how Aspero debuted under the characters of the Wednesday Night Rough Club two years ago, and that's how it's stayed. And because at Cervelo we know that flat out doesn't stay flat out for long without a little help from science, we've come back from the drawing board with a new Aspero. A faster Aspero, a lighter Aspero, and—dare we say it—an even better-looking Aspero. Our engineers like to say, "If it looks fast, it probably is"—but there's some truth to it, and Aspero-5 looks fast standing still. No cables in the wind, tubes derived from our library of aerodynamically proven shapes, and just a hint of a cut out in the seat tube to squeak out just a bit more tire clearance, 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 Aspero-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", or front wheel response to rider input, is the most critical factor in high-velocity handling. The ability to adjust trail with the two-position "Trail Mixer" to compensate for the extreme range of tire sizes ensures a uniform ride experience. Multiple Configurations We engineered the bike to fit most 700x42 or 650x49 tire/wheel combos, comfortably. Of course, there are variables—rim width, tire casing/tread depth—which will affect final clearance. IMPORTANT NOTE: We always recommend there to be 4mm of clearance around whichever tire/wheel combo is installed on the bike.

A NEW BIKE FOR CLASSIC RIDES We don't see road bikes as delicate machines meant only for putting watts into and receiving speed from. They're an extension of our soul, of the way we want to see our worlds, and the lives we want to live. Sometimes that means cutting across park grass, and sometimes it's seeing where that dirt road off to the left leads you. The Caledonia-5 is a bike for the modern road rider. The Caledonia is the bike we keep reaching for when we know the odometer's going well past the triple-digit mark. Long rides invariably have some smooth tarmac, some junk pavement over backroads, a cutty singletrack connector, and maybe even your own local Strade Bianche sector. So we built a bike that could take on all of them, do it well, and fit fenders in case the ominous clouds turn into a downpour 130km into your day. We developed the Caledonia-5 in collaboration with our World Tour riders to satisfy the need for a dedicated cobbles bike. Faster handling isn't necessarily better-we engineered the handling based on the specific use-case. In this case, it's Roubaix. Roubaix is harder on bikes than any other race on the calendar, and there's zero margin for error. We increased the rear center, lowered the BB, and increased the trail. The handling is still fast, but we've added stability. 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.

Rouvida - A New Frontier Rouvida gets you to fast, well, faster. Sleekly designed around the Fazua Ride60 motor, Rouvida delivers 60nM of torque paired to a 430wH battery, and assists you all the way up to 28mph—pro peloton speeds on the road, and edge-of-control-two-wheel-drifts off-road. That’s right, Rouvida comes in two configurations: road and gravel. We designed some clever interchangeable dropouts that significantly alter the geometry of the bike, so the road bike feels like a road bike, and the gravel bike feels like a gravel bike. No compromises, just speed. DOING MORE SO YOU CAN DO MORE We knew there was interest in both gravel and road performance e-bikes, so we designed dropouts that make one frame do double duty. A world away from your typical ‘flip chip,’ these interchangeable dropouts have the effect of rotating the entire frame to achieve the fit and handling you expect from a Cervélo road bike, and from a Cervélo gravel bike. When changing inserts (which must be purchased from your retailer), there is also a firmware update that needs to take place, and this service must be performed by your local Cervélo retailer. CLASSIC CERVÉLO While the design brief didn’t actually say, ‘Don’t make it look like an e-bike,’ it was definitely at the forefront of our thoughts throughout the process. Our bikes are refined, design-forward performance machines. The addition of a motor and battery couldn’t change that. From the reorientation of the battery to the relocation of the speed sensor, we made every effort to ensure that Rouvida meant Cervélo just as much as S5 or Áspero do. SMOOTH, POWERFUL, AND NATURAL Fazua’s latest offering, the Ride60, has already received accolades for its ability to blend seamlessly with your pedaling input to deliver a ride that feels like an analog bike, just with a lot more oomph. ALL IN THE DETAILS We considered every angle, and the result is a bike that looks right at home alongside any of our aero models. Reorienting the battery from the standard implementation saved 25g in the wind tunnel, the Road Control puts power and assist control in a natural location in the handlebar’s drop, and an indicator panel on top tube includes a USB charging port for lights or accessories.

The Soloist. It's a name from deep in our history, but immediately familiar to anyone with bike racing memories extending back to the early-2000s. It was the weapon of choice for top World Tour contenders on CSC and the Cervelo Test Team, and we're bringing it back for a new generation. The new Soloist is designed for the week-in, week-out rider and racer who can only justify one high-performance bike. It balances light weight and aerodynamic advantages to deliver a bike that really is 'just right'. Soloist comes in a hair lighter than S5, but significantly more aerodynamic than R5, and borrows the threaded bottom bracket standard you find on the R5-CX. It's a race bike that can accommodate mechanical and electronic shifting, can hammer out the training miles in all weather, and yet still has the chops to leap off the front at that decisive moment. That's the Soloist.

That's the Soloist. FAST LIKE S5, LIGHT LIKE R5 Soloist sits right between S5 and R5 on the performance scale, while having a price tag that's less World Tour, more Road Trip. It's about 250g heavier than R5, and 250g lighter than S5. It's 190g slower than S5, but 126g faster than R5. You get the idea. It's the 'just-right' answer for the rider trying to find a smart, intentional compromise. LOOKS LIKE A RACE BIKE, RIDES LIKE A RACE BIKE We took the handling geometry for the Soloist directly from R5. The R5 is beloved by pros and amateurs alike for its poise, stability, and precision when that killer climb turns into an even more killer descent. Soloist benefits from our decades of race bike geometry development, and comes out of the gate ready to go. HIDDEN FROM THE WIND, NO BLEED NECESSARY The cable routing is inside the frame for aerodynamics, but doesn't go through the stem. We developed our own system that threads the cables under the stem, but through the bearing cap. Whether your position changes or you loan the bike to a friend who uses a different stem length, you won't need to bleed the brakes to swap the stem. CLEARANCE TO BUZZ THE TOWER The Soloist fits tires up to 34mm (measured), and wheels wide enough to support them. BBRIGHT-47 The BBRighT-47 bottom bracket, which first appeared on the R5-CX, is ideal for those who log big miles but don't have a pro wrench checking the bike over every day. It makes BB swaps a breeze (convenient if you're burning through hand-me-down components) and extends the life of the frame.

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.

HAUL ASS, NOT CARGO A new breed of rider is emerging-one who loves the freedom and exploration that gravel culture was founded upon but who has a hunger to ride hard, to go all out, and to explore not just geography but personal limits. This frontier requires a new kind of gravel machine, one engineered not to roam the trails, but to race them. For these athletes, we engineered Aspero for pure, unapologetic speed, ready to take down finish lines, KOMs, PRs, and FKTs. A bike built without limits, for the riders looking to test them. It's stiff, Classics-racing stiff, and performs like you'd want a road bike to perform off-road. We think that makes sense, and it's what we were trying to do when we were stuffing bigger tires into our existing frames and swapping in aftermarket forks to get a 40mm tire up front. The flip-chip in the fork-we call it the Trail Mixer-keeps the trail measurement consistent whether you choose 700c or 650b tires. This maintains the bike's personality and handling characteristics when you switch from mid-fats to full-fat. There are as many different ways to do gravel as there are gravel bikes these days, but if you're toeing the start line, looking to stay with the lead group, and contend for the victory, Aspero is the bike to get you there.

We engineered Áspero for pure, unapologetic speed, ready to take down finish lines, KOMs, PRs, and FKTs. A bike built without limits, for the riders looking to test them. It's stiff-Classics-racing- stiff and performs like you'd want a road bike to perform off-road. We think that makes sense, and it's what we were trying to do when we were stuffing bigger tires into our existing frames and swapping in aftermarket forks to get a 40mm tire up front. 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 always recommend 4mm of clearance between the tire and frame. 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. BALANCED HANDLING - Stiffness and handling work together to ensure the bike tracks predictably and responds immediately to critical pedal and bracing inputs.

This allows for easy replacement in the event of damage but also enables you to adapt to new standards as they become available or remove the front derailleur mount completely if you choose a 1x system. - Integrated Accessory Mounts Integrated mounts enable the use of fenders, lights, and computers without compromising the aerodynamics or structure of your bike. The built-in mount systems provide a simple and clean-looking solution.

WELCOME TO THE ERA OF SPEED IN GRAVEL. A new breed of rider is emerging—one who loves the freedom and exploration that gravel culture was founded upon but who has a hunger to ride wild, to go full bore, and to explore not just geography but personal limits. This frontier requires a new kind of gravel machine, one engineered not to roam the trails, but to slay them. For these athletes, we created a machine engineered for pure, unapologetic speed—ready to take down finish lines, KOM leaderboards, PR’s, and FKT’s. A single bike that first generates maximum speed, then controls that speed across the variable conditions gravel athletes must conquer. A machine built without limits, for the riders willing to test them. ROAD RACING INSPIRED. GRAVEL RACING REFINED. It’s time to change the paradigm of gravel bike design from hauling gear slowly to empowering athletes quickly. Leveraging vast knowledge from road racing, the Aspero frame is designed with world tour stiffness for greater pedal power transfer, using less and lighter material to aid climbing and accelerating, while maximizing speeds with aerodynamic shapes critical to efficiency at speed. The Aspero lets you choose the tire that best suits the terrain so you're always in control, with clearance for 700c x 42 or 650B x 49 combinations. Since different outside rolling diameters of various wheel and tire combinations affect the bike handling, the fork includes a "Trail Mixer" design that adjusts trail to lessen the impact on handling when swapping between most common tire sizes. - Aspero full carbon frame and fork - SRAM Apex 1 drivetrain - Alexrims Boondocks-7D tubeless wheels - SRAM Apex HRD hydraulic disc brakes - Smartpak 400A top tube bag included
