I'm 6'2 and have 35.25 inside leg to floor. Look on Dolan website at Preffisio size chart. The 61 is perfect for me. I'm lost on a 56 and IMHO a 58 looks like I bought the wrong size. It's all down to the geometry of frame though, I know a man who rides 56 at the same height as me but his legs are shorter and arms longer so he has a very long stem slammed. Go and sit on bike is only answer but I recon unless his 56 has HUGE amount of seatpost showing it'll be too big. Bear in mind crank length too, big bikes tend to be 175mm. If he doesn't buy it share the bargain!
