DESCRIPTION
We made Crux, the lightest gravel bike in the world, even lighter. With the unrivaled capability of massive tire clearance and performance gravel geometry, it’s not just the ultimate expression of gravel performance—it’s your one-way ticket to gravel enlightenment.
With UDH and the all-new SRAM RED XPLR, the S-Works Crux drops another 102 grams. Featuring Roval Terra CLX II wheels, Terra Bars, Alpinist seat post, S-Works Power Saddle with Mirror, and Pathfinder Pro tires, the new S-Works Crux with SRAM RED XPLR is our most premium build.
- Lightest: 725g S-Works 12r frame. We took the breakthroughs that made Aethos the lightest bike ever and applied them to the Crux. The result? A gravel bike that climbs like a dream, floats over nightmarish terrain, and weighs less than a full bottle in your cage.
- Capable: 47c/650b x 2.1” tire clearance. More clearance means more capability. With Diverge-level tire clearance, Crux takes you anywhere you can imagine at full gas.
- Responsive: Nimble, supple, and reactive. Responsive at the pedals. Supple in the saddle. With performance gravel geometry and race-influenced fit inspired by Crux’s iconic history in ‘cross.
- Now equipped with UDH - Universal Derailleur Hanger - and built with the new SRAM RED XPLR, it features a 13-speed 10-46 cassette, power meter, updated lever ergonomics, and brake calipers that reduce brake effort by up to 80%.

The sizing chart is a great place to start when picking your next bike but everyone will fit a bike a bit differently. Your torso, arm, and leg lengths all play into what size of bike you may need. Plus, there's your own personal preference.
We always recommend swinging by the shop and taking the bike that you're looking for a spin to see how it feels. If you're unable to come by, looking at the geometry of your current bike and comparing it is a good place to start. If you have any further questions, our customer service team is there to help.
