Product Details
The Cervélo Áspero GRX RX825 Di2 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 thoughtful evolution that maintains legendary performance while adding enhanced comfort, improved drivetrain compatibility, and refined overall design aesthetics.
The updated Áspero features fully internal cable routing, creating a dramatically sleeker profile while delivering measurable aerodynamic improvements. The addition of UDH-compatible derailleur hanger opens possibilities for future drivetrain upgrades while simplifying maintenance requirements. Whether attacking 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.
The Shimano GRX RX825 Di2 1x12 electronic drivetrain with integrated 4iiii power meter provides precise wireless shifting and valuable training data for performance-focused riders. The Reserve 40|44TA GR carbon wheelset delivers proven gravel capability with aerodynamic efficiency and confident handling across mixed terrain conditions.
Perfect for competitive gravel racers and performance-focused riders who refuse to compromise on speed, the Áspero GRX RX825 Di2 remains the definitive choice for those demanding top-tier capability. Whether chasing podium positions or pursuing fast weekend adventures, this bike delivers race-proven performance that serious gravel riders depend on.
