How’d Specialized make the new Crux so light? They took the revolutionary breakthroughs that made Aethos the lightest bike ever and applied them to the Crux. The result? A gravel bike that climbs like a dream with the ability to float over nightmarish terrain.
At just 725 grams for the S-Works frame (just 850 grams for the Pro!) and 7.25kg for the S-Works build, the new Crux is the lightest gravel platform in the world with the exceptional capability of 47c x 700 / 650b x 2.1” tyre clearance and performance gravel geometry. It’s not just the ultimate expression of gravel performance, it’s your one-way ticket to gravel enlightenment.
We’ve summed it all up with a new metric—Clearance-to-Weight Ratio. The Specialized Crux fits up to a 700 x 47c because nothing unlocks a gravel bike’s full potential like the combination of an ultra-lightweight frame with massive tyre clearance.
