Here's another one in the area that is about the size of the bike in question, but with a horizontal top tube. This is approximately your size. Remember that sizing a production, off the shelf bike is a matter of compromise. A couple cm's here and there won't amount to a hill-o-beans. That said, stand over is something that I go higher on. I prefer a taller fit because it gives me more adjustment options as to stem length, etc. If it just brushes the jewels, it's ok with me. EDIT: There was a day when all road bikes were fitted that way.
