Cervélo Aspero GRX RX610 1 sea ice 2025

Cervélo Aspero GRX RX610 1 sea ice 12 speed carbon gravel bike 2025

Launched as a revolution in the gravel world, the 2025 Cervélo Aspero GRX RX610 1 sea ice returns with subtle changes that further improve its performance and versatility. This new model retains the speed-focused DNA of its predecessor, while gaining in comfort, compatibility and efficiency thanks to a threaded T47 bottom bracket, optimized cable routing and a UDH derailleur hanger compatible with the latest SRAM drivetrains.

The frame retains its responsiveness, but softens just the right amount: lowered seatstays for more compliance, adjusted front-end stiffness for more comfort on long rides, and clear space to let mud pass, directly inspired by the R5-CX model. Add to that an easily customizable cockpit and improved aerodynamics, and the new Áspero is ready to take on any gravel challenge, from long solo adventures to the most demanding competitions.
