PERFECT FOR

This product is perfect for the rider who wantsthe most advanced, aerodynamic 1x gravel machine available, specifically built for high-speed UCI gravel racing and podium-hunting.

Why we like the Cervélo Áspero-5 GRX RX825 Di2 1x

Massive Gear Range:

We love the pairing of a 48T aero chainring with the 10-51T XTR cassette, giving you enough top-end for road sprints and a 1:1 ratio for the steepest gravel climbs.

Premium Finishing:

The use of CeramicSpeed T47 bearings and Vittoria Corsa Pro Control 42mm tires means this bike is truly race-ready with zero "take-off" parts.

Refined Ride Quality:

The updated Áspero-5 layup is noticeably more compliant than the original, significantly reducing fatigue during 100+ mile gravel events.
