Specialized Crux Comp Gravel Bike 2026

The Specialized Crux Comp is the world’s lightest gravel bike, combining huge tyre clearance with performance gravel geometry. Built for speed, versatility and control, it delivers the ultimate expression of gravel performance.

Specialized Crux lightweight design

With frame weights of just 725 g for the S-Works 12r and 825 g for the 10r, the Crux applies the breakthroughs of the Aethos to gravel. The result is a bike that climbs with ease, floats over rough terrain and weighs less than a full bottle in the cage.

Specialized Crux with capable clearance

Clearance for 47c tyres or 650b x 2.1” means the Crux matches the capability of the Diverge, opening the door to more adventurous routes at full gas.

Responsive ride

Nimble, supple and reactive, the Crux is sharp at the pedals and smooth in the saddle. Its performance gravel geometry and race-inspired fit carry forward the heritage of Crux cyclocross racing into a modern gravel bike. Equipped with a Shimano GRX 12 speed groupset, DT G540 Disc wheels and 2Bliss Ready 700×40 mm Pathfinder tyres for reliable shifting, strength and traction across challenging terrain.
