The Specialized Crux Comp is one of those bikes that makes you reconsider what a gravel bike can actually do. Built around a Specialized Crux Comp carbon frame that tips the scales at just 825g in the 10r size, this is genuinely one of the lightest gravel bikes you can buy anywhere.
Specialized took the same engineering that made the Aethos the lightest road bike ever produced and applied it to the Crux. The result is a gravel bike that climbs with the efficiency of a race machine and handles rough terrain without beating you up in the process.
The Dune White colourway is a clean, understated finish that holds up well out on the road. If you've had your eye on the Specialized Crux white build specifically, this Comp version is one of the most accessible ways into that frame.
Spec-wise, it comes with a Shimano GRX 12-speed groupset. GRX is Shimano's dedicated gravel drivetrain, and it shifts cleanly and reliably whether you're grinding up a muddy climb or spinning along a loose gravel track. DT Swiss G540 Disc wheels sit underneath, tough enough to handle mixed surfaces day after day.
Tyres are 700x40mm Specialized Pathfinder in 2Bliss Ready (tubeless-compatible) spec, giving you plenty of volume to drop pressures and pick up grip on technical ground.
Tyre clearance goes up to 47c on 700c wheels, or 2.1" on 650b, which puts it at the capable end of the gravel spectrum. If you've been weighing up different bike types and wondering where the Crux lands, it sits between a fast road bike and a proper off-road machine.
It's nimble and responsive at the pedals, with performance geometry drawn from Specialized's cyclocross racing history, while staying genuinely comfortable over longer distances.
