All-new, molded, chainstay and down tube protection help defend the frame against impacts and quell nois

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.

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.

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.

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.
