The Specialized Crux DSW Cyclocross Bike is more than just the lightest alloy gravel bike ever made. Specialized applied everything they learnt from developing the carbon Crux and utilised their patented D’Aluisio Smartweld technology to bring this design to alloy. The result is the most capable, nimble, balanced, and responsive alloy gravel bike, perfect for fast, fun, high-performance riding. It’s the lightest too. Some might call it a carbon copy, but Specialized call it the Crux DSW.
"Specialized’s Crux DSW is a simple and lightweight Gravel Bike... The Crux DSW is not some kind of throwback bike. It features modern tyre clearance. Additionally, the Crux DSW has modern gravel geometry, with a longer relative reach and a slacker head tube angle paired with a shorter stem. The frame also uses a Universal Derailleur Hanger (UDH) to ensure compatibility with SRAM’s new Red AXS XPLR and other potential future gravel drivetrains." - Bicycling.com
Lightest Weight. At only 1399g*, the Crux DSW holds the title of the lightest alloy gravel frame in the world. When paired with a Fact 12r Crux carbon fork and a performance-focused build, the complete Crux DSW weighs just 9.37kg, making it unmatched among alloy gravel bikes.
*56cm frame in the lightest colorway. Production frames may vary.
Most Capable. The Crux DSW offers the same tyre clearance as its carbon sibling (up to 47mm and 2.1” on a 650b wheel) providing more capability. Combined with its tough yet light alloy frame, the Crux DSW is ready to take you anywhere at full speed.
Ultra-Responsive. Designed to be responsive at the pedals and supple in the saddle, the Crux DSW uses D’Aluisio Smartweld technology to fine-tune the alloy properties, delivering a ride quality previously only possible with carbon. It shares the same performance gravel geometry and race-inspired fit as the carbon Crux. A longer reach ensures better weight distribution for quick, confident handling, while a lower stack creates a performance-focused riding position. With a 72mm bottom-bracket drop, it strikes the perfect balance between agility and stability.
D’Aluisio Smartweld. Specialized's patented D’Aluisio Smartweld (DSW) process employs hydroforming to precisely match tube-to-tube joints, resulting in stronger welds and a lighter, more durable frame. This technique enables Specialized to create a unique single-piece downtube and bottom bracket for the Crux, reducing weight and enhancing responsiveness.
- Lightest: At 1399g for the Crux DSW frame (raw, unpainted), Specialized used their patented D’Aluisio Smartweld to create an alloy version of the carbon Crux. *56cm in the lightest colourway. Production frames may vary.
