The 2026 Specialized S-Works Crux Frameset represents the pinnacle of gravel performance, delivering unmatched lightness, capability, and responsiveness in one refined package. At just 725g for the S-Works 12r carbon frame (and 825g for the 10r), it is the lightest gravel frameset in the world—born from the same revolutionary engineering that made the Aethos the lightest road bike ever. This featherweight chassis climbs effortlessly, floats over rough terrain, and remains stable and confident at speed, all while weighing less than a full water bottle in your cage. With massive tire clearance for up to 47c or 650b x 2.1" tires, the Crux expands your horizons beyond traditional gravel, offering Diverge-level versatility so you can chase speed across virtually any surface without compromise.

Built around Rider-First Engineered™ FACT 12r carbon and paired with an S-Works FACT carbon fork, the frameset delivers precise handling, stiffness where you need it, and compliance where you want it. The performance gravel geometry—refined from the Crux’s storied cyclocross heritage—offers a race-ready fit that’s both nimble under power and supple in the saddle. The package is finished with a Roval Alpinist carbon seatpost for weight savings and ride quality, and a titanium-bolt alloy seat binder to secure your position. With its threaded bottom bracket, UDH dropout, and flat-mount disc compatibility, the S-Works Crux is equally future-proof and race-ready. Weighing just 1.46kg (size 56, including fork, seatpost, and binder), this frameset is your one-way ticket to gravel enlightenment—light, capable, and ready to dominate any road, trail, or race course.
