If bibs are meant to assist relocating "fleshy bits" away from the saddle and moving thighs, then they are really dumb for female riders. If tension in front of the shorts somehow isolates the fleshy bits from the dynamic bits and the saddle, why aren't they advertised as such?
It seems we have gotten to main feature of bibs, and it isn't removing the waist band. Its a junk locator.
