So my girlfriend is going to start riding a little here and there. I got her bike out yesterday to tune it up, and man is it heavy. It's a 2009 trek 820...steel frame. I think she will have some trouble getting around with it. What does everyone think? Any suggestions. I don't think i can really lighten up the bike that much, maybe grab a new-used aluminum frame. I wanted to get her into the group ride on Tuesdays at Allaire but I don't want her bike to give her a negative experience.
