Thanks for the info. Anyone have any suggestions for a newbie on how to tell what "feels right" I went to two LBS this weekend and one was putting me on a 17 frame and the other a 19.5. The 17 was a Giant and the 19.5 a Trek, but I still wouldn't think they can both be right?? I probably rode 8 different bikes this weekend around the parking lots, and they all feel different, but I'm not sure if I can determine what feels better with such a short ride. I'm sure I'm stressing about this too much, but with the back probs I want to get it right. - thanks.
