I'm about 5.8. The interesting thing is that when I first put in my size at the Competitive Cyclist site, right away it gave me the correct answer of 52-53cm for "Competitive fit" and higher, up to 56cm for the "French fit." That's another reason why I thought this shop was great. Very few shops really tried to find out exactly what size will fit me. I'd say always verify what a shop says by getting a few opinions. I am thinking that one of the reasons why I love this bike so much and why it has given me no aches whatsoever is that it fits me so well. And I haven't even had the time to go back to do a complete adjustment of the bike to my body while wearing my gear.
