Specialiized Chisel Hardtail Comp Mountain Bike 2025
The Chisel is purpose-built for modern cross-country trails and race courses, offering unparalleled speed and efficiency.

Weighing just 1,350g, it features size-tuned stiffness and modern XC attributes such as 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.
