Crux DSW Comp
The Crux DSW is more than the lightest alloy gravel bike ever made. We took everything we learned creating the carbon Crux and used our patented D’Aluisio Smartweld to make it a reality in alloy. We’ve created the most capable, nimble, balanced, and responsive alloy gravel bike ever made for fast, fun, high-performance riding. And yeah, it’s the lightest too. Some may call it a carbon copy, but we call it the Crux DSW.
Lightest Weight
At just 1399 grams* raw frame weight, the Crux DSW is the lightest alloy gravel frame in the world. Combine that with our S-Works FACT Carbon fork and a build curated for performance, and a complete Crux DSW tips the scales at 9.37kg — no alloy gravel bike can compete. *56cm, lightest colourway; production frames will vary.
Most Capable
More clearance means more capability — the Crux DSW shares the same tyre clearance as its carbon sibling: 47mm and up to 2.1″ on a 650b wheel. Combined with the tough, light alloy frame, the Crux DSW can take you anywhere you imagine at full gas.
Ultra-Responsive
Responsive at the pedals, supple in the saddle. D’Aluisio Smartweld fine-tunes the properties of alloy to deliver a ride previously impossible without carbon, paired with the same performance gravel geometry and race-influenced fit as the carbon Crux. A longer reach delivers better weight distribution for quick, confident handling, while a lower stack creates a performance-first position. At 72mm of bottom-bracket drop, it hits the sweet spot between nimble and stable.
D’Aluisio Smartweld
D’Aluisio Smartweld (DSW) is a patented engineering process that uses hydroforming to precisely match tube-to-tube joints for stronger welds and, ultimately, a lighter frame that can be twice as durable as a traditional alloy frame. The Smartweld technique creates a unique single-piece downtube and bottom bracket, shaving weight and amplifying responsiveness.
