I'm 5'4" with a 32 inseam and 31 sleeve . I tried a lot of wsd bikes from 48 to 54 but felt all cramped up. The LBS then put me on a unisex, 52 supersix 105, which I fell in love with. The more i ride it the more I use the drop bars, and the faster i'm getting on it. I have no problem climbing the hills, with the double on it, and i can keep up with the boys.
