We made the Crux, the world's lightest gravel bike, even lighter. We kept the generous fork and chainstay clearance for plus-sized tires and our performance-focused gravel geometry, and updated the frame with a UDH dropout and paired it with the new 1x13 SRAM RED XPLR groupset to shave another 102 grams. The new S-Works Crux is equipped with Roval Terra CLX II wheels, a Terra handlebar, Alpinist seatpost, S-Works Power Mirror saddle, and Pathfinder Pro tires.
