Specialized Chisel Comp 29" Mountain Bike 2021 - Hardtail MTB

The all-new Chisel Comp is the perfect bike to begin your journey into XC riding and racing, with all of the features to get you to that elusive "top step" at a price that leaves some jingle jangle left over for race entries.
This Chisel comes dressed with Shamano's crisp-shifting SLC 1x12 drivetrain and powerful M6100 hydraulic disc brakes, a 100mm (Size XS: 80mm) RockShox Judy Gold fork, and 25mm internal width alloy wheels wrapped in 2.3 Fast Track Control casing tires.
- The Chisel's all-new frame utilizes our D'Aluisio Smartweld technology that moves the hydroformed tube joints away from the areas of the highest stress, making the finished frame's balance of strength, rigidity, and weight more pronounced than any alloy frame in history. This not only makes the Chisel one of the lightest alloy hardtail frames coming in as light as 1,400g, but it also allows for tuned frame stiffness across all sizes.
- The new Chisel also houses all of the modern features that you expect from an XC bike, like Progressive XC Geometry with a 68-degree headtube angle and longer reach, internal cable routing, a threaded bottom bracket, boost spacing, 30.9mm dropper post compatibility, and 1x-only drivetrains.
Occasionally, without notice, manufacturers change product design and/or specifications.
