More to the point, if you're completely average in every respect, you don't need custom. THere's more to it than just measurements: flexibility, strength, riding style, kind of riding you do, fenders/racks/lights/whateverelse? And to be completely, absolutely honest about it, nobody NEEDS a custom bike: nobody NEEDS a bike at all. Yeah, I know, "HERESY!!!" But hey, I enjoy tweaking folks.
