Cervélo Áspero-5 frameset (colour Royal Mercury / grey)

The Cervélo Áspero‑5 is designed for speed, precision, and leading the race. As the most aerodynamic gravel bike ever, this frameset combines 30 years of Cervélo expertise in aerodynamics with the robustness and versatility required for unpaved roads. The result is a frameset that is 37 watts faster than its predecessor and 34 watts faster than its closest competitor, with the integrated aero handlebar and stem alone providing almost 6 watts of gain.

Lightweight and perfectly balanced

With an All-Carbon Aspero‑5 fork, a Cervélo SP27 carbon seatpost, and optimized geometry, the frameset is both lightweight and stable, even on the roughest gravel routes. The frame is 66 grams lighter than the previous model, without compromising stiffness or control.

Smart solutions for race and gravel adventures

The Áspero‑5 frameset offers clearance for tires up to 45mm, making it ready for the most challenging courses. The frame features downtube storage, ideal for an inner tube, tools, or a flat kit – completely out of the wind and integrated into the frame.

Complete with accessories

The frame can be combined with high-quality wheels and components to build a complete race-ready gravel bike. Accessories such as Cervélo In-Frame Storage Rolls, a Smartpak top tube bag, and Arundel bottle cages make it easy to carry everything you need on long rides.

For gravel racers and adventurers who demand uncompromising performance
