The Specialized Crux Expert Disc Cyclocross Bike is engineered for performance.

A new lighter frame that optimises stiffness and compliance no matter the frame size keeps power transfer explosive and is complemented perfectly by a carbon Roval wheelset. A SRAM Force 1x groupset ensures that gears shift smoothly and whilst the geometry favours fast cornering, the flat bottom top tube makes it easy to carry when negotiating race obstacles.

Specialized Crux Expert Disc Cyclocross Bike 2020

This isn't about bikepacking or a do-it-all big-clearance rig, the Specialized Crux Expert Disc Cyclocross Bike is an out-and-out racing weapon, refined for fast laps and specifically engineered for podium performances. Using the same FACT Rider-First Engineered carbon that's used on the Specialized Tarmac, the frame features size-specific tube shapes and layups for consistent performance and ride feel regardless of size. The frame is stiff and light so for punchy climbs the power transfer will drive instant acceleration, and yet with a slightly dropped seat collar there's new compliance as well that will help take some of the sting out of rough courses.

The large frame triangle and flat bottom top tube make the bike easier to shoulder for when scampering over obstacles and the lower bottom bracket will let you pin it into corners with confidence. Easily taking a 33mm tyre, the frame still retains plenty of extra clearance for shedding mud when conditions are particularly sticky.

A low maintenance 1x SRAM Force hydraulic groupset keeps your gear shifting sweet and the tubeless ready Rovel C 38 disc carbon wheels complete this well-specced build.


  • Roval C 38 Disc carbon fibre wheelset
  • SRAM Force 1 hydraulic disc groupset
  • CruX frame now comes in around a scant 900 grams for a 56cm
  • Large opening to the front triangle and a flat bottom for ease of shouldering
  • Plenty of tyre clearance for efficiently shedding mud
