Why not submit your anatomic inseam/ pubic bone height..as someone here and /or click-on a site..take a consensus. The point of a "right" or "wrong" size is based on a start-off point.With the exception of specific or special needs,an optimum size is a happy medium,it affords the greatest amount of adjustability..what's your an. inseam? did he check? why speak in hypotheticals ? what's the actual measurement?..Kelly, a good example,a sprinter he was.My friend has a hip problem,he goes with a smaller frame..there are exceptions but..since you're askin'..what's your PBH ??
