David, when you draw up a rear triangle, do you just go measure the tire on a rim? I think I will have a problem finding a 650bx2.25" wheel/tire to measure. I usually just rely in bikecad, but I trust it for this size.
I measure if I have the actual tire and wheel on hand. Otherwise, I find that the Bead Seat Diameter + 2x tire width in millimeters is pretty close for the diameter of the tire/wheel. For a 650b x 2.25" tire that would be 584 + (2 x 57.15) = 698.3mm. I divide that by 2 and get 349.15mm from the axle center to the peak of the tire.
