Product Details

The Cervélo Áspero GRX RX820 established its reputation in 2019 by reshaping gravel expectations with an aggressive, race-first philosophy that prioritized uncompromising speed above all else. This newest iteration receives a thoughtful evolution that maintains that legendary performance while adding enhanced comfort, improved drivetrain compatibility, and a refined overall design aesthetic.

The updated Áspero features a fully internal cable routing system that creates a dramatically sleeker profile while delivering measurable aerodynamic improvements. The addition of a UDH-compatible derailleur hanger opens possibilities for future drivetrain upgrades while simplifying maintenance requirements. Whether attacking on technical terrain or maintaining high speeds on open fire roads, the refined frame cuts through wind resistance with greater efficiency, helping riders conserve valuable energy over extended, demanding efforts.

Drawing inspiration from Cervélo's proven R5-CX cyclocross expertise, engineers refined the rear triangle geometry and front-end compliance characteristics to better absorb trail chatter while preserving the snappy, responsive handling that defines the Áspero experience. Generous mud clearance ensures reliable performance across challenging weather conditions and varied surface adventures, from muddy cyclocross races to remote gravel expeditions.

Perfect for competitive gravel racers and performance-focused riders who refuse to compromise on speed, the Áspero GRX RX820 remains the definitive choice for those demanding top-tier capability. Whether chasing podium positions or pursuing fast weekend adventures, this bike delivers the race-proven performance that serious gravel riders depend on.
