Specialized S-Works Crux Gravel Bike 2026
The Specialized S-Works Crux, already the lightest gravel bike in the world, has been made even lighter while retaining its exceptional capability and performance gravel geometry. With massive tyre clearance and a race-inspired fit, it remains the ultimate expression of gravel performance.
Crux Lightweight Construction
With a 725 g S-Works 12r carbon frame, the Crux draws on breakthroughs from the Aethos to deliver a gravel bike that climbs effortlessly and floats over the roughest terrain, all while weighing less than a full water bottle.
Capable Crux clearance
Tyre clearance of 47 mm with 700c wheels or 2.1 inches with 650b wheels ensures versatility and confidence on any surface, matching the capability of the Diverge for limitless adventure at speed.
Responsive Specialized Crux ride
Nimble, supple and reactive, the Crux delivers sharp responsiveness at the pedals and comfort in the saddle. Its geometry is tuned for performance gravel riding and inspired by the bike’s cyclocross heritage.
The S-Works Crux is now equipped with UDH (Universal Derailleur Hanger) and SRAM’s new RED XPLR groupset, offering a 13 speed 10-46 cassette, integrated power meter, updated lever ergonomics and brake calipers that reduce effort by up to 80 percent. Premium finishing kit includes Roval Terra CLX II wheels, Terra bars, an Alpinist seatpost, S-Works Power Saddle with Mirror technology and Pathfinder Pro tyres, creating the most advanced Crux build to date.
