I've been reading a bunch of posts for the past week or so and was hoping you guys could help me out. Haven't purchased a bike in years and I'm looking for a new one to go off to college with. I'll be going to school in dc so I wanted a commuter/hybrid. I've been around to a few local bike shops as well as REI and have heard a lot of different things. I'll just list some of the bikes I was looking at and would appreciate if you could comment on or recommend one out of the pack. I will be going back to test ride some of them later this week but really wanted to narrow it down. So far I've only ridden the sirrus. Thanks in advanced for all your help.
