Specialized Crux Comp 2024

The Crux is the world's lightest gravel bike, with ample tire clearance and geometry designed for performance and speed. Now the gravel bike also lights up with performance and lightness. The Crux Comp rides Shimano GRX 12-speed drivetrain, sturdy DT G540 Disc wheels and Pathfinder Pro 2Bliss Ready tires, 700x38mm.

Lightness
The FACT 10r frame weighing only 825 grams is inspired by the Aethos, Specialized's lightest bike. The result is a gravel bike that climbs with agility, passes nightmarish terrain with ease, and weighs less than your full water bottle.

Capacity
You can fit tires with a cross-section up to 47c or 650b x 2.1". Tire clearance is that of the Diverge and allow the Crux to take you anywhere at full speed.

Responsiveness
The new CruX is agile and responsive. The new performance gravel geometry provides a racing stance as per the good tradition of the CruX in cyclocross racing.
