  • Fox Float CTD Air rear shock features Boost Valve technology along with the CTD ProPedal platform to give the bike plush, efficient suspension with great bottom-out protection
  • CTD settings (Climb, Trail, Descend) and external rebound adjustments make it simple and easy to tune the ride to the trail
  • 2x10 drivetrain offers weight savings with fast, precise shifts and a gear range savvy enough to handle races and all-day riding
  • Drivetrain highlights include the stiff and tough RaceFace Respond crankset with bash guard, SRAM X9 Type 2 rear derailleur and SRAM X7 shifters
  • Avid Elixir 5 hydraulic disc brakes deliver responsive braking thanks to a 200mm rotor up front and 180mm rotor in the back
