I got the 6700! That bike is so good I think that the rim is a little bent though. It came with the Hayes Nines those brakes are really nice. One problem with the bike is that th e seat can be really uncomfortable in certain areas if you know what I mean) I want like a comfortable seat. Will a seat that is like just for your butt work or should I not use that for xc biking? I really like this bike especially the 27 gears. I can't wait to ride it again. Please respond with the seat issue, and my cleats are reallyhard to clip out and I often fall. How can I loosen the tension of the springs? I don't wanna mes sup the bike.
