I know there are a lot of threads about sizing, but I haven't been able to find an answer to my current situation. I'm trying to decide between a 52 and 54cm Windsor Clockwork. My question is about the stand-over height. The Windsor website has a nifty matrix to help one choose a size. http://www.windsorbicycles.com/sizing.htm

For my measurements: 5'7" w/ 30 inch leg (measured via inseam), the chart suggests a 54 or 56. But, the standover height listed on bikesdirect for a 54 is 30.8 inches. So my question is: should your leg length be greater than the stand-over height in order to have a good fit? I just don't understand how someone with a 30 inch inseam can comfortably straddle a 54cm bike if the stand-over is 30.8 inches.

Thanks.
