Model Summary
The Crux DSW Frameset - D'Aluisio Smartweld Alloy is more than the lightest alloy gravel frame ever made. Specialized took everything learned building the carbon Crux and used its patented D'Aluisio Smartweld process — precision hydroforming that matches tube-to-tube joints for stronger, lighter welds — to bring that ride quality to alloy. At a claimed 1,399 grams (56cm, lightest colourway), it's the lightest alloy gravel frame in the world, paired here with the same S-Works FACT Carbon fork used across the carbon Crux range. It shares the same 47mm/650b x 2.1" tyre clearance and performance gravel geometry as its carbon sibling, with a longer reach, lower stack, and 72mm of bottom-bracket drop striking a sweet spot between nimble and stable. Some might call it a carbon copy — Specialized calls it the Crux DSW.
Key Highlights
- Patented D'Aluisio Smartweld construction: hydroformed E5 Premium Aluminum tubing with a unique single-piece downtube and bottom bracket junction shaves weight and boosts responsiveness.
- Lightest alloy gravel frame in the world: a claimed 1,399 grams (56cm, lightest colourway) puts genuine carbon-like performance within reach of an alloy frame.
- Paired with S-Works FACT Carbon fork: the same fork used across the carbon Crux range, for consistent ride quality regardless of frame material.
- Same tyre clearance as the carbon Crux: fits up to 47mm on 700c or 2.1" on 650b wheels.
- Performance-first geometry: a longer reach and lower stack for a race-ready position, with 72mm of bottom-bracket drop striking the balance between nimble and stable.
