I'm looking at a trek 2100 somebody has for sale on craigslist that is in my area, i'm going to see if i can look at it. he wants $300 , it is a few years old it looks like black with blue or maybe the black is just carbon fiber? anyway what do you think of that kind of a deal? the bike looks like it's in good condition. right now i'm riding an older univega. i love trek other than this univega all i have had are trek mountain bikes.
