A QUESTION OF WATTS
In 2019, Áspero took the world by storm by heralding a "new era of speed in gravel." The new Áspero stays true to those early, simpler days of true gravel riding, but with a few improvements: a threaded bottom bracket, cleaner cable routing, and a UDH-compatible derailleur hanger for those who want to use SRAM drivetrains. And, of course, it's more aerodynamic. In the case of Áspero, however, aerodynamic performance isn't so much about speed as it is about energy savings, achieved through reduced aerodynamic drag. After a hard day in a headwind, the three watts saved compared to the previous Áspero could be equivalent to one less energy gel for your stomach to digest—try it and believe it!
In addition to reducing drag, we've also lowered the seatstays for a little more rear end grip and slightly reduced front-end stiffness to make the final hours of those really long races less painful. Between the dropped seatstays, we've also added a little more mud clearance, capitalizing on what we learned from the R5-CX (and the 2023 Unbound Mudfest). These are a lot of seemingly small improvements, but they add up to so many others. The result is a bike that feels a lot like the original Áspero, but is actually faster, more comfortable, and more versatile.
T47 Bottom Bracket
Áspero uses the asymmetric T47a threaded bottom bracket we pioneered on the R5-CX. This simple and easy-to-use interface allows us to offer the benefits of BBRight in a more user-friendly form.
UNIVERSAL DERAILLEUR HANGAR
We've used SRAM's Universal Derailleur Hanger (UDH) as standard on the new Áspero. It's ideal if you want to maximize your riding experience with the latest SRAM drivetrains while also ensuring compatibility with future drivetrain developments.
Easy and customizable front end
The Áspero shares the same bearing dimensions as the R5, Soloist, R5-CX, and Caledonia, meaning you can use any headset and stem combination. Want a super-racing, fully integrated look? Check out the R5 ST31 and HB13 models.
