Was at a shop coupled of days ago and the tech said the exact same thing. I think the mens version is called the Rapid. I have compared the specs and it looks like the SO height is about .5 shorter, BUT the length is longer. I am assuming that womens bikes are made with "shorter torsos" as the only difference. Man, there are soooo many choices! Oh, I'm only 5"7 1/2 , but I've got a short inseam.
