would need more (accurate) measurements to give a better answer.
an IRO 59 is really a 55 c-c with a 57cm TT. IRO measures seat tube to the top of the collar. I'm 6'2" with pretty short legs, and that's the size that I'd pick.

If your cycling inseam is really 32" you might want to consider going custom.

/don't let 53-11 see that picture. you'll never get him to shut up about aerodynamics, long cranks or "forward positioning"
