Mainly a roadie, and my MTB is a pretty basic one, but is getting more and more use. I get a lot of pedal bob, and I'd like to eliminate that. I love the FS feeling when riding more tricky stuff, but not while climbing and while just riding dirt trails with my wife. Since adding a hardtail to the bike stable is probably out, replacing the rear shock seems to be a fairly simple option, but I"m surprised that I don't find them for sale at Performance, Supergo or Jensen. The current shock is pretty basic - a Vanilla R - and replacing it with something else fairly basic, even a Vanilla RL, would be fine. Where can I find shocks for sale online?
