We deliver! Just say when and how.
The riders have spoken! For the fifth year in a row, Specialized has been crowned the #1 “Drop Bar Bike Brand” in the prestigious Gran Fondo Best Brand Awards for 2023. We innovate for riders, and year after year, our bikes are loved by the most discerning riders. Thank you!
The Crux is the lightest gravel bike in the world, with the exceptional capability of massive tire clearance and performance gravel geometry. It’s not just the ultimate expression of gravel performance, it’s 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 Crux’s iconic history in ‘cross.
