Cube Reaction GTC Pro review

Aug 2016 · Guy Kesteven

A great value bike with better than expected spec, but you might want to upgrade the tyres. Buy if you're a racer or trail warrior looking for a responsive and smooth carbon ride at a great price

Highs
  • Efficiently driven, smooth riding, full feature full carbon frame at an alloy version price. Outstanding value Shimano XT transmission spec with decent wheels and fork

Lows
  • The cheap Active Line tyres are fast and hard-wearing, but lack grip and supple smoothness in wet conditions
