Specialized Crux DSW Comp — SRAM Apex XPLR

The lightest alloy gravel race bike ever made, built for pure speed and real‑world versatility.

The Specialized Crux DSW Comp takes everything riders love about the carbon Crux and brings it to an elite‑level alloy platform using Specialized’s patented D’Aluisio Smartweld (DSW) technology. The result is the world’s lightest alloy gravel frame — just 1399g — paired with a FACT 12r carbon fork for a complete build that’s shockingly responsive, balanced, and fast on any terrain.

Designed as a true gravel race bike, the Crux DSW Comp delivers razor‑sharp handling, efficient power transfer, and a supple ride feel that rivals carbon. With 47mm tire clearance (or 2.1” on 650b), it’s equally at home on chunky Midwest gravel, CX courses, or long mixed‑surface days.

The SRAM Apex XPLR 1×12 drivetrain keeps things simple, durable, and adventure‑ready, while hydraulic Apex brakes provide confident stopping power in all conditions. It’s a build that prioritizes performance without unnecessary fluff — fast, capable, and ready to race straight out of the box.
