Hey, my husband has an aunt and uncle who live in San Angelo. Totally off topic.

Given your background, you want something that is going to rock. Bike sizing is truly an individual thing. I'm just under 5'5' and have 3 road bikes - a 51, a 53 and a 54. When I bought the 54 in 2003 I thought it was perfect and I rode several centuries and 3 double centuries on it. Now I've decided it's too big and I'm getting ready to sell it. My riding style has changed over the years. Yours will too probably.
