thanks for everyone's input. I dunno. I think if i was living in the city area, I would know what bike to get... Ok, so sounds like the 7100 is out then. I guess if i get a mountain bike, I think im gonna look at the 3500. I think the store has this model w/ my size too. I didnt get to go test ride the 7.2 today. will be doing that monday.. I'll speak to the guy and ask what they think the 3500.
