Crux DSW Frameset

Lightest Alloy Gravel Bike Ever
The Crux DSW isn’t just another alloy gravel bike—it’s the lightest, most capable, and most responsive ever made. Drawing on everything we learned from the carbon Crux, we applied our patented D’Aluisio Smartweld (DSW) technology to alloy, delivering a bike that’s nimble, balanced, and fun at high speeds. Some may call it a carbon copy, but we call it the Crux DSW.

Lightweight Performance
Weighing just 1,399 grams for a 56cm frame*, the Crux DSW is the lightest alloy gravel frame in the world. Pair it with our Fact12r Crux carbon fork and a performance-focused build, and a complete bike tips the scales at just 9.37 kg—unmatched by any other alloy gravel bike.

Maximum Capability
With tire clearance up to 47mm (650b up to 2.1”), the Crux DSW can handle anything you throw at it. The tough yet lightweight alloy frame allows for fast, confident riding across diverse terrain, from gravel roads to challenging off-road tracks.

Ultra-Responsive Ride
Thanks to D’Aluisio Smartweld, the Crux DSW delivers a ride previously impossible with alloy. The frame is responsive at the pedals, supple in the saddle, and shaped with the same performance gravel geometry as the carbon Crux. A longer reach improves weight distribution for precise handling, while a lower stack creates a performance-first position. With a 72mm bottom-bracket drop, the bike strikes the perfect balance between nimble and stable.

D’Aluisio Smartweld Technology
Our patented DSW process uses hydroforming to match tube-to-tube joints perfectly. This creates stronger, lighter welds and a frame that can be twice as durable as traditional alloy frames. A single-piece downtube and bottom bracket maximize stiffness, responsiveness, and efficiency.
