well the fremont is a good bike but if you want an aluminum bike and are unhappy with the fremont's lack of... umm... street cred? i'd get something a little cooler. fuji track pro maybe? langster city? you are kinda lacking a real track bike if you're gonna have three ssfg's, well... get one that's got some track geo. i vote for fuji track pro.

or build up a leader 735tr.

i seriously think 2 bikes should be the limit for someone in college. any more is too much hassle.
