Of course BB height will be affected by the choice of tires. I presume framebuilders make assumptions about the tire size to be used, presumably the same assumptions used to set the fork and rear bridge clearances.

I have been measuring from the ground to the bottom of the bottom bracket shell. It now occurs to me that perhaps I should be measuring to the center of the axle. Hopefully this will engender less heat than the chainstay discussion.
