Like many of their high performance hardtails, Cube have built two versions of the Reaction GTC SL to give their riders the best choice. This version is the 29in wheel model. For the 650b / 27.5in wheel model, search: 84800.

Cube’s Reaction GTC SL takes the already impressive performance of the Race model, but adds a superlight Fox 32 Float fork into the mix for an even better quality ride. The upgraded fork brings with it Fox’s famously smooth travel, with remote lockout and the new-for-2016 FIT4 damping system, giving supreme handling on both 27.5in and 29er models. 

Like the Race model, the SL also benefits from an X-12 through axle for a stiff rear triangle that keeps the weight down. It also retains the all-new Shimano M8000 XT groupset, with 22 smooth and reliable gears and 180/160mm hydraulic disc brakes.

Key features:

  • Gran Turismo Composite frame with optimised use of high modulus fibres
  • Fox 32 Float FIT4 fork with remote lockout
  • 2 x 11 Shimano XT M8000 22 speed gears & 180/160mm hydraulic disc brakes
  • Fulcrum Red 44 wheelset
