I've been using my 7.5FX to commute to campus and it really is a nice bike. But sometimes the student population is so dense when I'm riding that I have to jump off into the dirt/grass to dodge them. The FX is pretty rough on anything unpaved. I've found myself taking my mountain bike instead on certain days when I know I'll have a lot of people to dodge. I'm thinking I would have done better with an 8.5DS.
So my question...is there any good way to outfit a 7.5FX with a suspension fork, or will it just hose the geometry too much? Perhaps my best bet is just taking a loss, selling the FX, and getting a DS.
