Product Details

The Crux is the lightest gravel bike in the world, with the exceptional capability of massive tire clearance and performance gravel geometry. Its not just the ultimate expression of gravel performance, its your one-way ticket to gravel enlightenment.

This Crux Comp comes spec’d with a reliable and smooth-shifting Shimano GRX 12-speed groupset, tough DT G540 Disc wheels, and 2Bliss Ready, 700x38mm Pathfinder Pro tires that hookup over nasty terrain.

• Lightest: 725g S-Works 12r and 825g 10r frames. We took the revolutionary breakthroughs that made Aethos the lightest bike ever and applied them to the Crux. The result? A gravel bike that climbs like a dream, floats over nightmarish terrain, and weighs less than a full bottle in your cage.
• Capable: 47c/650b x 2.1 tire clearance. More clearance means more capability. With Diverge-level tire clearance, Crux takes you anywhere you can imagine, at full gas.
• Responsive: Nimble, supple, and reactive. Responsive at the pedals. Supple in the saddle. With performance gravel geometry and race-influenced fit inspired by Cruxs iconic history in cross.
