WTF? some of these posts sound crazy to me:
kurrenkarm (sp?) is 5'9" and rides a 52
same for neptunetitan
some other guy is 5'10" and rides a 50?!
progre-ss is 5'6" and is riding a 46?!!!

I'm 5'4" and I ride a 49 and a 50 (the 50 has a slightly shorter top tube and therefore fits better, I think) comfortably. Should I try a smaller frame? Am I not really as comfortable as I could or should be? Or are these other guys just riding frames that are small for them. I know everyone's body/geometry is different and ride what feels right blah blah blah, but there has to be some relative scale...

huh?
