Norco Storm 4 review - MBR

Jun 2019 · Jamie Darlow

The Norco Storm 4 is our only 29er on test and as such it gets off to a good start, rolling over rough ground more easily than the 27.5in wheel bikes.

Highs
  • Bigger 29in wheels smooth out the bumps. Great size range

Lows
  • The build kit doesn't maximise the frame's potential
