2025 Specialized CruX DSW Frameset

Lightest Weight

At just 1399 grams*, the Crux DSW is the lightest alloy gravel frame in the world. Combine that with Specialized’s Fact12r Crux 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 in the lightest colourway. Production frames will vary.

Most Capable

More clearance means more capability—that’s why the Crux DSW has the same tyre clearance as its carbon sibling—47mm and up to 2.1” on a 650b wheel. Combine this with the tough and light alloy frame, and Crux DSW can take you anywhere you imagine at full gas.

Ultra-Responsive

Responsive at the pedals. Supple in the saddle. Specialized have used D’Aluisio Smartweld to fine-tune the properties of alloy to deliver a ride previously impossible without carbon and combine it 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, Specialized hit the sweet spot between nimble and stable.

D’Aluisio Smartweld

D’Aluisio Smartweld – or DSW – is a patented engineering process that uses hydroforming to precisely match tube-to-tube joints for better, stronger welds and, ultimately, a lighter frame that can be twice as durable as a traditional alloy frame. Speicalized’s Smartweld technique helps them create a unique single-piece downtube and bottom bracket for the Crux, shaving weight and amplifying responsiveness.
