Specialized Crux Comp Bike (2026)

2026 Specialized Crux Comp Shimano GRX gravel bike, Dune White. Specialized manufacturer's reference: 91426-5054

The Crux is the world's lightest gravel bike. With a large wheelbase and perfect geometry for maximum performance off-road, this bike will be your springboard to gravel heaven.

The Crux Comp features a silky-smooth Shimano GRX 12-speed groupset, durable DT G540 Disc wheels, and 700 x 38 mm Pathfinder Pro tires that are 2Bliss Ready and ready to take on any terrain, no matter how rough it is.

• Lighter: The 12-speed carbon frame weighs 725 g and the 10-speed carbon frame weighs 825 g. We've taken the revolutionary advancements that made the Aethos the lightest bike ever and applied them to the Crux. The result? A gravel bike that climbs like a charm, flies over rough terrain, and weighs less than the full bottle in your bottle cage.
• Performance: The tire clearance is 47c/650b x 2.1”. More space means more performance. With the same clearance as the Diverge, the Crux takes you anywhere at full speed.
• A bike that responds: fast, supple, and reactive. Sensitive on the pedals. Comfortable in the saddle. With a geometry adapted to the performance that gravel demands and a design influenced by racing and inspired by the Crux's iconic history in cyclocross.
