Gearing

A bike with lower gearing will be easier to ride up steep hills, while a higher top end means it will pedal faster down hills.

Reviews
MBR
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

The Rockhopper has a tapered head tube, which is good news for anyone who wants to upgrade the slightly disappointing SR Suntour XCM fork fitted to the front of the bike.
