Cervélo Aspero-5 Force AXS 1 (colour Royal Mercury / grey) Gravel Bike - complete bike

The Cervélo Áspero‑5 is built to lead. As the most aerodynamic gravel bike ever, it combines 30 years of Cervélo's aerodynamic expertise with the raw reality of gravel racing. The result? 37 watts faster than the previous model and 34 watts faster than its closest competitor. A significant part of this gain comes from the integrated aero handlebar and stem, accounting for nearly 6 watts on their own.

Lightweight and efficient

Despite a larger surface area for better aerodynamics, the new Áspero‑5 is 66 grams lighter than its predecessor. This not only makes it faster but also more agile and responsive on technical courses.

Optimized geometry for every course

Whether you ride with the same tire size (e.g., 42mm front and rear) for stability on rough terrain, or a 4mm difference between front and rear tires (e.g., 40mm front, 44mm rear) for maximum aerodynamics and sharper handling on less technical routes, the Áspero‑5 adapts perfectly.

Smart storage, aerodynamically integrated

The Áspero‑5 introduces downtube storage, first applied to the P-Series triathlon bikes. This clever solution allows for a spare tube, tools, and a flat kit to be stored inside the frame – completely out of the wind and lightweight, so you don't lose speed.

Race-ready from the first meter

With clearance for tires up to 45mm and a threaded bottom bracket, the Áspero‑5 is race-ready right out of the box. Its world debut was truly legendary: UCI Gravel World Champion Marianne Vos won with this bike in the rainbow jersey, and today it is used by some of the most elite riders in the world.

Maximum gravel performance

The Áspero‑5 is the ultimate choice for those seeking uncompromising speed, aerodynamics, and gravel performance.
