Introducing the 2026 Crux, the lightest gravel bike in the world, now even lighter. With unparalleled capabilities, including massive tire clearance and performance gravel geometry, this bike is not just the ultimate expression of gravel performance—it’s a one-way ticket to gravel enlightenment.

Equipped with UDH and the all-new SRAM RED XPLR, the S-Works Crux has shed an additional 102 grams. It features Roval Terra CLX II wheels, Terra Bars, an Alpinist seat post, an S-Works Power Saddle with Mirror, and Pathfinder Pro tires, making it the most premium build available.

Weighing in at just 725 grams for the S-Works 12r frame, the breakthroughs that made the Aethos the lightest bike ever have been applied to the Crux. The result is a gravel bike that climbs effortlessly, glides over challenging terrain, and weighs less than a whole bottle in your cage. With a tire clearance of 47c/650b x 2.1”, the Crux offers unmatched capability.

Now upgraded with UDH - Universal Derailleur Hanger - and built around the new SRAM RED XPLR, the Crux includes a 13-speed 10-46 cassette, power meter, refined lever ergonomics, and brake calipers that reduce brake effort by up to 80%. Elevate your gravel riding experience with the S-Works Crux.
