Years ago, I recall that a gal in our bike club rode a 51cm Trek 5200 WSD, and was around 5'4". The bike fit her perfectly. I test rode the 47cm size of the same bike and found that I felt a little stretched out and would want a slightly shorter (or higher) stem than the stock.

Funny, isn't it? That's why test rides are so important, but it can be hard to find smaller bikes to ride in many cases. I've bought several bikes online and gotten lucky, but I'm also very familiar with the geometry that works for me.

I was thinking the same thing in reading this. I'm 5'0". I've stated have short legs and a longer torso. I was fit perfectly to a 47cm Trek Lexa, although my next purchase is going to be a Madone. No one had one of those in a 47cm I could test. I was also at my old LBS where I got to test the Lexa. Well actually my old LBS's sister shop in Charlotte. (I lived in Mooresville, NC which is now 5 hours away). I also prefer a more stretched out feel. We finally figured out this was the biggest issue I have with getting comfortable on a Mountain bike. Once we finally figured that out, we were able to change the stem and get me more stretched out on the Mountain bike so now I'm more comfortable on it. Although I'm still much, much more comfortable on my road bike. I've only had the road bike for about 9 months now, where as I've had mountain bikes for years. (I am also fairly flexible as I participated in gymnastics as a kid and off and on through college, though never competitively.)
