Accomodating Seat Angle
After drawing out 4 frames on top of each other in full size, I realized that seat angle is not quantified when fitting riders to a frame. In other words, we quantify reach, but going from the BB back to the saddle we do not have a measurement for it, and the seat angle does seem to affect the overall fit of the bike. Yes, the saddle can be adjusted fore aft, however when comparing frames, there should be a number for this measurement. Tell me where I have gone wrong here.
