  • 120mm-travel RockShox XC32 fork w/ 15mm thru-axle for plush and precise handling
  • Tektro Gemini Comp hydraulic disc brakes for consistent, all-weather stopping power
  • SRAM X9 Type 2, 10-speed, medium cage rear derailleur for precise shifting
  • Stout XC 650b aluminum rims with 21mm inner width rims are trail ready
  • Specialized Ground Control 2.3" tires w/ a fast-rolling yet grippy tread
  • New A1 Premium Aluminum EVO 650b frame delivers a more aggressive trail performance
