Specialized Chisel Comp X1 29" Mountain Bike 2019

Specialized's Chisel Comp X1 Mountain Bike is perfect if you're getting into XC racing, with it's lightweight, strong, and stiff yet compliant frame. This performance frame has a race-oriented geometry and is fitted with a RockShox Judy Gold 29 fork, offering 90mm - 100mm of travel to soak up the bump and shocks of the roughest trails.

The one-by setup from Shimano's SLX groupset provides wide 11-46T gearing for tackling all terrains, and powerful Shimano MT-501 hydraulic disc brakes are powerful and modulated in all conditions. The 29-inch wheels and 2.3 inch Fast Trak tyres are optimised for weight and traction and roll fast and smooth.


  • Lightweight and ultra-stiff M5 aluminium
  • With speed-focussed XC 29 Geometry, D'Aluisio Smartweld technology, and internal cable routing, you get a bike that compromises nothing in delivering explosive speed, confident handling, and hassle-free maintenance
  • Rocks and bumps are soaked up via the RockShox Judy Gold fork with 90/100 millimetres of travel (size-specific). It features proprietary technology from RockShox, like its Solo Air™ spring, that maintains an ideal equilibrium, as well as being one of the lightest air springs on the market
  • The Shimano Deore SLX rear derailleur is durable, precise, and will keep you shifting crisply for miles to come
