Thanks for the reply greenfix. I am planning in mostly riding this thing on the trail. I picked it up yesterday, and have been spending a significant amount of time getting used to the clipless pedals(that's a whole 'nother thread, I know). Nonetheless, I am VERY happy with this bike...I am 6'1" and was a little shy about the 21" frame(seemed big in my mind), but I am glad that's what I got...it fits great and so far at my experience level feels very light. The shop I bought if from has been awesome. I don't know, I guess if I was on this board BEFORE I bought a bike, I might have done something different, but the 4900 is a really great bike...at least for me. I would recommend people check it out.
