The Specialized Crux Expert with SRAM Rival XPLR AXS E1 is built for riders chasing the purest expression of gravel performance—lightweight, responsive, and capable. As the world’s lightest gravel bike platform, the Crux leverages design breakthroughs from the ultra-minimalist Aethos to deliver a frame that’s remarkably light (just 825g for the FACT 10r version) without compromising strength or handling. Whether you’re charging up steep climbs or dancing over loose, rocky terrain, the Crux’s efficient carbon layup and Rider-First Engineering ensure balanced stiffness and comfort across all sizes.

The Crux Expert is equipped with SRAM’s latest Rival XPLR AXS E1 groupset—bringing wireless 13-speed shifting, a wide-range 10-46t cassette, and powerful hydraulic disc brakes to a broader range of riders. Designed specifically for gravel, Rival XPLR AXS delivers smooth and quiet shifting across varied terrain with a simplified 1x drivetrain that reduces clutter and increases reliability. The Rival crankset and chain work in unison to provide fast, precise engagement whether you're rolling pavement or grinding fire roads.

Versatility is a defining feature of the Crux. With clearance for up to 47c tires or 650b x 2.1”, the bike is ready for everything from race-day speed to adventure-level exploration. The Roval Terra C wheels combine a 25mm internal width and 32mm depth for stability and compliance, paired with 700x40mm Pathfinder Pro tires for confident grip and smooth rolling on a variety of surfaces. A full carbon S-Works fork up front keeps the ride sharp and planted, while the 8.1 kg total weight (size 56) ensures the bike feels fast and nimble from the first pedal stroke.

Comfort and control are rounded out with a well-equipped cockpit: a Body Geometry Power Expert saddle, Roval Terra carbon seatpost with 20mm offset, and Specialized Adventure Gear handlebars with a generous 12° flare for added leverage and wrist clearance on rough terrain. Whether you’re lining up for a gravel race or heading out for an epic solo ride, the Crux Expert offers elite-level capability, refined ride quality, and the precision of modern wireless shifting in one lightweight, gravel-optimized package.
