ROSE GROUND CONTROL 3 2020 on test – XC efficiency meets trail performance

Aug 2020 · Christoph Bayer

Great price, great spec, great looks, but is its performance great too? The ROSE GROUND CONTROL seems almost too good to be true.

Highs
  • Very efficient

  • Direct handling

  • Excellent value for money

Lows
  • Requires lots of strength and input from the rider

  • The front wheel doesn't stay planted on steep climbs

  • Not very comfortable
