Reply To: Upgrade Specialized Rockhopper 29er



I recently rebuilt my ’11 Specialized Stumpy 29.  My favorite upgrade of all was definitely going from 3 x 9 to  1 x 10 gearing.  I tried for a 1x 11 but the gear ratio was too wide.  With an rear derailleur extension I was able to get 10 of them.  If you buy a matched set the compatibility is better.   Learn from my mistakes.  Having only one chain ring up front changes the whole game on technical trails.  Never look down again.
