Specialized Crux DSW Comp | Gravel Bike

The Crux DSW Comp is what happens when Specialized's engineers ask "what if alloy could ride like carbon?" — and then go build it. At just 1,399 grams for the frame, the Crux DSW is the world's lightest alloy gravel frame. Pair that with a FACT 12r carbon fork and a curated performance build, and the complete bike tips the scales at 9.37 kg — territory typically reserved for carbon bikes costing twice as much. With 47mm tire clearance, race-influenced gravel geometry, and the same DNA as the carbon Crux that's won countless cyclocross and gravel races, the DSW Comp is the carbon-copy answer for riders who want every gram of performance without the carbon-copy price tag.

D'ALUISIO SMARTWELD TECHNOLOGY: Specialized's patented hydroforming process precisely matches tube-to-tube joints for stronger welds, lighter weight, and a frame up to twice as durable as traditional alloy. The unique single-piece downtube and bottom bracket assembly shaves weight where it matters most and amplifies stiffness and responsiveness at the heart of the frame.

WORLD'S LIGHTEST ALLOY GRAVEL FRAME: 1,399g for the frame alone (size 56, raw). Full bike weight of 9.37 kg means you can climb, sprint, and shoulder it through technical sections without feeling the alloy penalty.

MASSIVE TIRE CLEARANCE: Up to 47mm with 700c wheels, or 2.1" with 650b — the same clearance as the carbon Crux and on par with the Diverge. Run skinny tires for fast all-road, drop in 650b knobbies for proper backcountry exploration, or land anywhere in between.

PERFORMANCE GRAVEL GEOMETRY: A longer reach delivers better weight distribution for quick, confident handling, while a lower stack puts you in a performance-first position. 72mm of bottom-bracket drop hits the sweet spot between nimble and stable — perfect for the wide variety of speeds and surfaces gravel throws at you.

RACE-READY SRAM APEX XPLR 1x12: Reliable mechanical SRAM Apex XPLR 1x12 drivetrain with an 11-44T cassette and 40T chainring offers a wide, gravel-friendly gear range with crisp, repeatable shifting. SRAM Apex hydraulic disc brakes deliver consistent power in any conditions.
