Why do men feel they need to lie about their height? One of the first questions I ask someone when I'm fitting them for a new bike is their height just to get a rough idea of where to start. Most men add at least a couple of inches. The best one was just the other day, I asked and he replied 5'10.5". I'm 5'8" and may be even slightly taller than him. Probably had a 30" inseam. I put him on a bike that he could hardly raise his leg over. When his privates were being squished by the top tube I think he may have gotten the idea. It's quite funny actually.
