With the Cube Reaction range, the choice between 29er and 650b / 27.5in wheels is entirely up to you. The Reaction GTC Pro is available as both a 650b / 27.5in wheel model which you can see here, or as a 29er which you can find by searching 84797.
The Cube Reaction GTC Pro 2X is the perfect choice for riders looking for a mountain bike which can do everything from fast trail blasts to racing - in both 27.5 and 29 inch versions.
It starts with a very light but stiff monocoque carbon frame made using Cube’s Twin Mold technology, designed around their 2nd generation Agile Riding Geometry approach and integrating a strong, stiff & lightweight adaptable X12 hangar system.
This frame is a solid foundation upon which the Cube Reaction GTC Pro is built, with a responsive RockShox Recon Silver fork featuring remote PopLoc lockout and 100mm suspension travel, plus an all-new 22 speed Shimano M8000 series XT gearset giving a wide and reliable range of gears to keep you on the power at any speed.
The icing on the cake is the 180/160mm Deore hydraulic disc brakes which keep you in control of the smooth-rolling Answer Atac MA wheelset at all times.
