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. 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. Want a super-racy, fully-internal look? Grab the ST31 and HB13 from R5.

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.

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.

Oh, and you can fit a 34mm tire in there. Or 31mm with fenders. REMOVABLE FDM Our bolt-on front derailleur mount is made from high-strength aluminum alloy and attaches to the frame with two countersunk screws. 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.
