Specialized Crux DSW Comp 2025 Gravel Bike

The Crux DSW is the world’s lightest alloy gravel bike, built using Specialized’s patented D’Aluisio Smartweld Technology to deliver carbon-level performance in an alloy package. At just 1,399g for the frame, paired with a FACT 12r carbon fork, it offers a fast, ultra-capable platform designed for high-performance gravel riding. With generous tire clearance of 47mm—or up to 2.1" on 650b wheels—it handles rough terrain with ease while remaining impressively responsive and efficient.

Its performance gravel geometry mirrors that of the carbon Crux, offering a long reach, low stack, and ideal bottom-bracket drop for balanced, confident handling. Smartweld construction creates stronger, lighter joints and a uniquely engineered downtube-BB assembly, enhancing stiffness, durability, and ride quality. The result is an alloy gravel bike that feels fast, nimble, and refined in every scenario.
