Specialized Crux DSW Comp Alloy Gravel Bike 2026 The Crux DSW is a high-performance alloy gravel bike that takes everything learned from the carbon Crux and applies it to alloy using the patented D’Aluisio Smartweld process. It delivers a nimble, balanced, and responsive ride while remaining the lightest alloy gravel bike ever made, designed for fast, fun, and high-performance riding. Lightweight Design Weighing just 1399 grams for the 56cm frame in the lightest colourway, the Crux DSW is the world’s lightest alloy gravel frame. Paired with the FACT12r Crux carbon fork and a performance-focused build, a complete Crux DSW weighs 9.37kg, outmatching any competing alloy gravel bike. Capability With tyre clearance matching its carbon sibling of up to 47mm and 2.1 on a 650b wheel, the Crux DSW can tackle a wide range of terrain at full speed. The tough yet light alloy frame provides the durability and versatility needed for any adventure. Responsive Ride The Crux DSW is designed to be responsive at the pedals and supple in the saddle. D’Aluisio Smartweld fine-tunes the alloy properties to deliver a ride previously achievable only with carbon. Performance gravel geometry and a race-influenced fit ensure confident handling, with a longer reach for better weight distribution and a lower stack for a performance-first position. A 72mm bottom-bracket drop balances nimbleness with stability. D’Aluisio Smartweld Technology D’Aluisio Smartweld, or DSW, is a patented hydroforming process that precisely matches tube-to-tube joints, producing stronger, lighter, and more durable frames. This technique enables the creation of a unique single-piece downtube and bottom bracket, reducing weight and enhancing responsiveness.
