Specialized Crux Cyclocross and Gravel Bike: The World’s Lightest Gravel Bike

The Specialized Crux Cyclocross and Gravel Bike is renowned for being the lightest gravel bike globally, delivering unparalleled tyre clearance and advanced gravel geometry. This bike epitomises gravel riding excellence and is your gateway to an unparalleled gravel experience.

The Crux Comp model features a dependable and smooth-shifting Shimano GRX 12-speed groupset, rugged DT G540 Disc wheels, and 2Bliss Ready 700x38mm Pathfinder Pro tyres that excel on challenging terrain.

Unmatched Lightness

Featherweight Frame: The Crux comes with an S-Works 12r frame weighing just 725g and a 10r frame at 825g. Utilising the same groundbreaking innovations from the Aethos (the lightest bike ever made) this gravel bike climbs effortlessly, glides over tough trails, and weighs less than a full water bottle.

Exceptional Capability

Generous Tyre Clearance: Boasting 47c or 650b x 2.1” tyre clearance, the Crux provides maximum versatility. With clearance comparable to the Diverge, this bike enables you to conquer any terrain with confidence and speed.

Superior Responsiveness

Agile Performance: Designed for nimbleness and responsiveness, the Crux features advanced gravel geometry and a race-inspired fit. This ensures a bike that’s both reactive at the pedals and comfortable in the saddle, drawing from the Crux’s celebrated cyclocross legacy.
