Cube Reaction GTC SL review

Sep 2016 · Guy Kesteven

A great-value example of exactly how fast and much fun an XC hardtail should be. Buy if you're looking for a fast, fun cross country ride

Highs
  • Excellent balance of efficiency and speed sustain over rough terrain

  • Smooth, remote control Fox fork and full Shimano XT spec

Lows
  • Slightly heavy frame, fragile tyres and temperamental XT brakes
