I've been looking to get a bike and needed some suggestions on which one to buy. I would be using the bike for mainly as another form of exercise on bike trails and a little bit on roads. The Diamondback Trace Comp and the Trek DS 8.3 are two bikes that I am considering. Would these be a good fit for what I want to do? Does anyone have any insight on these bikes? Any advice would be helpful. Also, if you need to know anymore info, just ask.
