Crux DSW Frameset - D'Aluisio Smartweld Alloy

The Crux DSW is the lightest alloy gravel bike ever made, combining everything learned from creating the carbon Crux with Specialized's patented D'Aluisio Smartweld technology. This frame delivers the most capable, nimble, balanced, and responsive alloy gravel bike for fast, fun, high-performance riding. At just 1399 grams, the Crux DSW is the lightest alloy gravel frame in the world. When paired with the Fact12r Crux carbon fork and a performance-curated build, a complete Crux DSW weighs just 9.37kg—no other alloy gravel bike can compete on weight. The frame offers the same tire clearance as its carbon sibling, accommodating 47mm tires and up to 2.1" on a 650b wheel. This capability combined with the tough, light alloy frame allows the Crux DSW to handle any terrain at full speed. D'Aluisio Smartweld is a patented engineering process using hydroforming to precisely match tube-to-tube joints for stronger welds and a lighter frame that can be twice as durable as traditional alloy frames. This technique creates a unique single-piece downtube and bottom bracket, shaving weight and amplifying responsiveness. The geometry delivers responsive handling with a longer reach for better weight distribution and quick, confident cornering, while a lower stack creates a performance-first position. At 72mm of bottom-bracket drop, the frame hits the sweet spot between nimble and stable, providing a ride that is responsive at the pedals and supple in the saddle.
