Technical Specifications
With its M4 frame, hydraulic disc brakes, and trail-ready components, the Rockhopper Comp looks to find the fire road and sniff out the singletrack.
  • Fully butted M4 alloy frame for lightweight confidence over the roughest trails
  • Specialized Captain Sport tires lend a perfect knob pattern for diverse conditions
  • Light and durable double-walled alloy rims are tough enough to handle the rough stuff
  • Tektro Draco hydraulic disc brakes with dual pistons assure precision braking under any conditions
  • Shimano Alivio 9-speed rear derailleur and Rapidfire trigger shifters for reliable, high-end performance
  • Shimano crankset with forged alloy arms and Octalink-splined BB interface means greater durability and better shifting performance
  • Custom-tuned SR Suntour suspension fork with hydraulic damping, lockout with lightweight magnesium lowers, and alloy steerer delivers the supple ride qualities of a high-end fork
