The Cervélo Áspero GRX RX825 Di2 1 is designed for riders who want gravel bike speed without sacrificing capability when the terrain gets rougher. Combining aerodynamic influence with off-road-focused handling, the carbon frame feels responsive under power while maintaining the stability needed for fast gravel descents and unpredictable surfaces.
Its geometry strikes a well-balanced position between aggressive efficiency and all-day confidence. The front end offers direct steering and a lively ride feel, while enough stability is built in to keep the bike composed through loose corners, technical sectors and rougher tracks. Whether you are lining up for a gravel race or heading out for long mixed-surface rides, the Áspero encourages fast, committed riding.
A key highlight is Shimano’s GRX RX825 Di2 1x12-speed electronic drivetrain. Wireless shifting keeps gear changes crisp and reliable even in muddy or demanding conditions, while the wide-range 10-51 cassette delivers plenty of gearing for steep climbs and faster gravel sections. The simplified 1x setup reduces maintenance and keeps operation intuitive when conditions become more demanding.
Shimano GRX hydraulic disc brakes provide dependable stopping power and control in all weather conditions, helping maintain confidence on technical descents and rough terrain.
Reserve 40TA GR and 44TA GR carbon wheels keep weight low while adding durability and efficiency across mixed terrain. They are paired with WTB Vulpine 700x45c tyres featuring a fast-rolling tread pattern that balances speed on hardpack with grip on looser gravel and dirt tracks. Clearance for tyres up to 45mm allows flexibility for different riding styles, from faster race setups to more comfort-focused adventure builds.
Finishing details such as the flared Cervélo carbon handlebar, carbon seatpost and clean internal cable routing help enhance comfort, control and overall integration. Multiple mounting points also make it easy to carry extra equipment for longer rides and bikepacking trips.
Fast, lightweight and purpose-built for modern gravel riding, the Áspero GRX RX825 Di2 1 delivers a sharp and engaging ride feel for riders who like to push the pace beyond the tarmac.
