Description
Specialized Crux Pro Gravel Bike 2026
The Specialized Crux is the lightest gravel bike in the world, combining exceptional capability with performance gravel geometry. With huge tyre clearance and a design inspired by racing, it represents the ultimate expression of gravel performance.
At just 725 g for the S-Works 12r frame and 825 g for the 10r frame, the Crux benefits from the same breakthroughs that made the Aethos the lightest road bike ever. The result is a gravel bike that climbs effortlessly, floats over rough terrain and weighs less than a full bottle in the cage.
With clearance for 47 mm tyres on 700c wheels or 2.1 inch tyres on 650b wheels, the Crux matches the Diverge for all-terrain versatility, giving riders the freedom to go anywhere at speed.
Crux Gravel Geometry
Nimble, supple and reactive, the Crux is sharp at the pedals and smooth in the saddle. Its performance gravel geometry and race-inspired fit draw from the model’s cyclocross heritage, ensuring confidence and control on every ride.
Specialized's lightweight and durable Crux
The Crux Pro is equipped with SRAM Force XPLR AXS, offering effortless electronic shifting, lighter weight and a wide 13 speed gear range. It rolls on durable and lightweight Roval Terra CL Disc wheels paired with 2Bliss Ready 700x40 mm Pathfinder Pro tyres for reliable grip and speed across demanding terrain.
