Technical Specifications
Trails were built to be ridden hard, and that's what the Rockhopper EVO does best. With a 120mm fork, 29-inch wheels, slightly more relaxed geometry, and Tektro Gemini disc brakes, the EVO will tame the toughest trails.
  • Tektro Gemini hydraulic disc brakes for consistent, all-weather stopping power
  • SRAM X7 Type 2, 10-speed, rear derailleur for precise shifting
  • Stout XC 29” aluminum with 20mm inner width rims are trail ready
  • Custom 2x10 crankset and drivetrain for efficacy and precise shifting
  • 120mm-travel custom SR Suntour XCR-AIR fork w/ exclusive Multi-Circuit Damping for smooth performance
  • Specialized Ground Control 2.3" tires w/ a fast-rolling yet grippy tread
  • New A1 Premium Aluminum EVO 29 frame delivers a more aggressive trail performance
