Frame

Cervélo Áspero-5 carbon frame geared towards Gravel Racing

The Cervélo Áspero-5 2027 is developed for pure gravel performance. Its carbon frame leverages over 30 years of Cervélo expertise in aerodynamics, with a clear objective: to offer a faster, more efficient, and race-ready bike.

A major aerodynamic advantage

The new Áspero-5 is advertised as being 37 watts faster than the previous generation and 34 watts faster than its closest competitor. The frame shapes, integration, and cockpit have been optimized to reduce drag on fast gravel courses.

Optimized weight

Despite the addition of surfaces designed to improve aerodynamics, this new generation is announced as being 66g lighter than its predecessor. The result is a bike that is more responsive, more agile, and more efficient at accelerating.

Integrated storage in the diagonal tube

The Áspero-5 incorporates a storage system in the downtube, directly inspired by the Cervélo P-Series. It allows you to carry an inner tube, tools and a repair kit inside the frame, in a clean, discreet and aerodynamic way.

Fork and geometry

Cervélo All-Carbon Carbon Fork

The Cervélo All-Carbon Tapered Áspero Fork provides precision, stiffness and control on fast gravel courses, degraded roads and more technical trails.

Tire clearance up to 45 mm

The frame accepts tires up to 45 mm, in order to adapt the bike to different terrains: rolling gravel, rough tracks, fast paths or long distances.

Optimized geometry for matching or contrasting tires

With tires of the same width, for example 42 mm front and rear, the Áspero-5 maintains stable and reassuring handling. Cervélo has also optimized the geometry for a setup with a 4 mm difference between the front and rear, for example 40 mm at the front and 44 mm at the rear, in order to improve aerodynamics and handling on less technical courses.

Cockpit

Cervélo HB16 carbon handlebar

The Cervélo HB16 Carbon handlebar with 31.8 mm clamping contributes to the bike's aerodynamic integration. It offers a high-performance position, precise steering, and good control on fast terrain.

Cervelo ST31 carbon stem

The Cervélo ST31 Carbon stem completes the cockpit. The handlebar and stem combination contributes to an aerodynamic saving of nearly 6 watts on the new Áspero-5.
