Cube Reaction GTC One

Oct 2017

If you're after a seriously rapid and lightweight cross-country race bike then Cube's Reaction series of hardtails has always delivered, but the Reaction GTC One gets the added benefit of Shimano's clever Di2 electric shifting at a bargain price. The complete buyer's guide to mountain bikes - how get the best bike for you Review: Ritchey P-29 - a steel, short-travel hardtail with heritage Prefer drop bars?

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
