The stand over height on my Steamroller is 30.7 and i'm 5'8 and it's fine it's a size 53cm. Please don't buy a new bike according to stand over height. I also rode a Scwhinn Madison that had a really tall standover height and it was also fine, it was something like 31.5 yeah my body parts rested on it and everything but it wasn't uncomfortable in the slightest and I barely ever stood over it.
