Lots of good advice. Thank you! I'm a fairly common height for a woman - 5'4", but I am about equally distributed between torso and leg length. I am not long-legged. I still have 25 pounds to lose, but it's falling off pretty quickly as I'm averaging over 150 miles per week. I am hoping that the bike shops will have a size that will fit me on the floor. I am leery about paying a lot of money for something without test riding it. Since I'm riding a lot, I'm realizing what is good and bad about my current bikes. I want to take my time and be very cautious about this purchase, as it will be one that has to last a long time. Thanks and please keep the advice coming!
