2025 Cervélo Áspero-5 Shimano GRX Di2 Gravel Bike

Unmatched aerodynamic speed and race-ready performance for serious gravel riders.

The Cervélo Áspero-5 GRX Di2 is a cutting-edge gravel bike engineered to dominate the front of the pack. Designed for high-speed off-road racing, it combines Cervélo’s three decades of aerodynamic innovation with modern gravel-specific features. From UCI Gravel World Champion Marianne Vos to weekend warriors chasing KOMs, this bike delivers elite-level performance right out of the box.

Aerodynamics lead the way with a design that’s 37 Watts faster than the previous Áspero and 34 Watts quicker than the nearest competitor, with integrated aero cockpit components alone shaving off nearly 6 Watts. It’s also 66g lighter than the outgoing model, despite a larger surface area that boosts efficiency even further. The updated geometry allows for stable, predictable handling on rough terrain, while a variable tyre width setup (e.g. 40mm front, 44mm rear) refines aerodynamics and responsiveness for faster, less technical routes.

With internal downtube storage – first seen on Cervélo’s triathlon bikes – the Áspero-5 also offers smart practicality, letting you store a spare tube and tools without disrupting airflow. Add in a threaded T47 bottom bracket, clearance for up to 45mm tyres, and top-tier Shimano GRX RX825 Di2 electronic shifting, and you’ve got a bike that’s born to race and built to win.
