I am looking at a Trek Marlin 29er. Does anyone have any input on that bike or maybe another 29 inch bike I should look at. I will use it daily to ride to work and weekends when I have the time. The on road conditions in the area I will ride are sometimes rougher than off road conditions. Even though I enjoy riding and have been doing it for a while I am not well versed on the terminology. So please break down any advice to the idiot level so I can understand it. Oh yeah, before I tell you how much the shop wants for the bike what should I pay for this Trek?
