Specialized Crux Comp Gravel Bike 2024
The Crux stands as the world's lightest gravel bike, boasting exceptional tire clearance and a performance gravel geometry. It goes beyond being the pinnacle of gravel performance; it serves as your exclusive passage to gravel enlightenment.
Unmatched Lightness: The S-Works 12r frame weighs merely 725g, while the 10r frame is a feather-light 825g. Leveraging the groundbreaking innovations from the Aethos, the Crux is a gravel bike that ascends effortlessly, glides over challenging terrain, all while tipping the scales at less than a full water bottle in your cage.
Impressive Capability: Featuring a tire clearance of 47c/650b x 2.1", the Crux opens up boundless possibilities. With tire clearance akin to the Diverge, the Crux is ready to tackle any terrain at full throttle.
Agile Responsiveness: Nimble, supple, and responsive—these are the characteristics that define the Crux. Its responsiveness at the pedals and suppleness in the saddle, combined with performance gravel geometry and a race-influenced fit inspired by its iconic history in 'cross, make it a true marvel.
