We deliver! Just say when and how.
Crux, the lightest gravel bike in the world, just got lighter. It’s the unrivaled capability of massive tire clearance and performance gravel geometry, updated with UDH - Universal Derailleur Hanger - and new SRAM RED XPLR to shave another 102 grams.
We made Crux, the lightest gravel bike in the world, even lighter. With the unrivaled capability of massive tire clearance combined with nimble gravel geometry, it’s not just the ultimate expression of gravel performance—it’s your one-way ticket to gravel enlightenment.
With Universal Derailleur Hanger and the all-new SRAM RED XPLR, the S-Works Crux LTD drops another 102 grams. Featuring Roval Terra CLX II wheels, Terra Bars, Alpinist seat post, S-Works Power Saddle with Mirror, and S-Works Pathfinder tires, the new S-Works Crux LTD with SRAM RED XPLR is our most premium build.
S-Works Crux LTD keeps the incredible features coming. The hand-painted “Blurred Impasto” technique makes each frame unique, while an included Hammerhead Karoo III Bike computer and custom K-edge mount will have you chasing KOMs and pioneering new routes on day one. But with only 50 of these bikes ever made, you’ll need to act quickly.
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. With performance gravel geometry and race-influenced fit inspired by Crux’s iconic history in ‘cross, it’s responsive at the pedals and supple in the saddle.
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 braking effort by up to 80%.
