Specialized Rockhopper Comp - MBR

Aug 2017 · James Bracey

Specialized has been at pains to keep the Rockhopper Comp's wheels firmly planted in the broadest sense of XC, mainly to appeal to a broad sector of riders.

Highs
  • Ride quality of the aluminium frame

  • Sensibly specced handlebar width and stem length

Lows
  • Low level spec for the price

  • Brake and gear shifters difficult to set up perfectly
