Description
The 2026 Specialized S-Works Crux with SRAM RED XPLR sets a new benchmark in ultralight gravel performance. At just 6.94 kg (15 lb, 4.8 oz) in a size 56, it’s the lightest gravel race bike Specialized has ever made—thanks to a Rider-First Engineered™ FACT 12r carbon frame weighing only 725 grams. Drawing inspiration from the Aethos, the Crux leverages ultra-refined layup techniques and minimalist tube shapes to deliver the ultimate blend of stiffness, weight savings, and ride feel. It’s the gravel racer’s dream: a machine that climbs effortlessly, accelerates without hesitation, and disappears beneath you when the road gets rough.
Capable of clearing 47c tires—or up to 2.1" on 650b wheels—the Crux matches the Diverge’s legendary clearance but with sharper race-oriented geometry. Its nimble, reactive handling and supple compliance allow you to charge through singletrack, deep gravel, or race-day mud with confidence and control. The performance gravel geometry strikes a balance between speed and stability, honoring the Crux's cyclocross lineage while optimizing for long-distance dirt escapades. It’s a bike built to transcend boundaries—on the racecourse or the ridgeline.
The SRAM RED XPLR drivetrain brings cutting-edge 13-speed wireless shifting to the Crux, offering a 10-46t cassette paired with a 40t front chainring and integrated power meter for maximum range and data-driven performance. The new UDH-equipped dropout ensures futureproof compatibility and drivetrain protection. Refined lever ergonomics, precise modulation, and updated calipers deliver a 80% reduction in brake effort—ideal for the rigors of mixed-terrain riding. Every component reflects top-tier intent, from the Supacaz bar tape to the titanium hardware in the S-Works SL stem.
Rolling on Roval’s Terra CLX II carbon wheels wrapped in 700x40c Pathfinder Pro tires, the Crux delivers speed, traction, and comfort in equal measure. With lightweight carbon cockpit components including the Roval Terra handlebar and Alpinist seatpost, plus the mirror-printed S-Works Power saddle, every touchpoint is optimized for endurance, power transfer, and off-road confidence. Whether you're toeing the start line or seeking gravel enlightenment, the S-Works Crux SRAM RED XPLR edition is the ultimate tool for the job.
