The 2023 Crux stands as the world's lightest gravel bike, boasting remarkable features like an expansive tire clearance for tackling rugged terrain and a gravel-specific geometry optimized for top-tier performance. It transcends beyond being a mere representation of gravel excellence; it serves as your exclusive pass to discover the true essence of gravel riding.

The Crux Expert variant comes equipped with the intuitive SRAM Rival eTap AXS hydraulic disc groupset, ensuring seamless and precise shifting. Complementing this are the durable Roval Terra C Disc wheels, along with the 2Bliss Ready, 700x38mm Pathfinder Pro tires that provide exceptional traction even on the most challenging landscapes.

With frame weights as light as 725g for the S-Works 12r and 825g for the 10r, Specialized has harnessed the groundbreaking innovations that made the Aethos the world's lightest bike and incorporated them into the Crux. The outcome? A gravel bike that ascends with unparalleled ease, effortlessly glides over the harshest terrains, and weighs less than a full water bottle in your bottle cage.

Its capabilities are underscored by a tire clearance of up to 47c/650b x 2.1”, akin to the Diverge series. This level of clearance translates to boundless versatility. The Crux embraces the spirit of adventure, allowing you to venture wherever your imagination takes you, with unbridled speed and energy.

In terms of responsiveness, the Crux exhibits agility, suppleness, and quick reactions. It swiftly responds to your pedaling efforts and offers a comfortable experience in the saddle. The performance gravel geometry and the racing-inspired fit, drawing from the Crux's rich heritage in cyclocross, contribute to its nimbleness and exceptional handling.
