I am looking to upgrade the fork on my rockhopper would you recommend this one http://minneapolis.craigslist.org/hn...18500656.html?
For $100? If the steerer is long enough, for sure. Then invest a little to have it serviced and you should have a nice fork for a little money.
Great fork. Still running one on my 2008 GF steel hard tail. For $100, I'd say that's the perfect fork for a Rockhopper.
Grab it before someone else does but first check the steer tube length
