Cervelo Aspero Force AXS 1

Cervelo made the new Aspero more aerodynamic than its predecessor, though the gains here are framed less as raw speed and more as energy conservation over a long gravel race, the kind of marginal savings that matter more on the back half of a five-hour effort than on a short group ride. To offset that stiffer, more aero front end, Cervelo dropped the seat stays for added compliance out back, a change borrowed from lessons learned developing the R5-CX. That same cross-pollination shows up in the frame's mud clearance, widened after testing at events like Unbound, so the carbon frame holds up when the course turns into a swamp instead of gravel. The fork is Cervelo's own all-carbon design, and the frame runs a T47a asymmetric threaded bottom bracket, a rider-serviceable standard the brand pioneered on the R5-CX that trades the stiffness of press-fit for a bottom bracket you can actually service at home without a shop visit. A UDH-compatible derailleur hanger rounds out the frame, keeping the door open for future drivetrain updates.

The build on this Aspero Force AXS 1 leans into wide-range gearing over a second front chainring. Sram's Force XPLR AXS E1 shifters and hydraulic disc brakes handle shifting and stopping, paired with a SRAM X0 Eagle AXS T-Type rear derailleur and a 10-52 12-speed cassette, a mullet-style setup that borrows Eagle's mountain bike range for a single 46-tooth chainring up front. It's a drivetrain built for riders who'd rather have one wide range to…
