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.Key Features1,399g alloy frame using D’Aluisio Smartweld for exceptional strength-to-weightFACT 12r carbon fork paired with performance-focused gravel geometry47mm tire clearance (2.1" on 650b) for maximum versatility and capabilityLong reach, low stack, and 72mm BB drop for confident, responsive handlingSingle-piece downtube/BB Smartweld design for improved stiffness and reduced weightSpecificationsFramesetFrame: Specialized E5 Premium Aluminum Disc frame with D'Aluisio Smartweld Technology, hydroformed aluminum tubing, tapered head tube, threaded BB, UDH dropoutFork: S-Works FACT Carbon, 12x100mm thru-axle, flat-mount discWheelsRims: DT G540, Centerlock Disc, Tubeless Ready, 25mm internal widthTyres: Pathfinder Pro 2BR, 700x38DrivetrainCrankset: SRAM APEX XPLR, 40tShifters: SRAM APEX, 12spRear Derailleur: SRAM APEX XPLR, MechanicalChain: SRAM APEX 12SCassette: SRAM PG 1231, XPLR, 11-44Bottom Bracket: SRAM DUB BSA 68 WideComponentsHandlebar: Specialized Adventure Gear, 118.9mm drop x 70mm reach x 12º flareStem: Specialized, 3D-forged alloy, 4-bolt, 7-degree riseGrips: Supacaz Super Sticky KushBrakes: SRAM APEX, Hydraulic DiscSaddle: Body Geometry Power Sport, steel railsSeatpost: Alloy, 2-bolt Clamp, 12mm offset, 27.2mm, anti-corrosion hardwareSpecialized Crux Sizing52cm54cm56cm58cmRider Height (cm)163 – 168168 – 175175 – 183183 – 191Rider Height (ft)5'4 – 5'65'6 – 5'95'9 – 6'06'0 – 6'3
