But Tony, usually only builders are equipped to measure from "...a horizontal line..." as you state above, i.e., they have fixtures and drawings and tools and such. SO ON AN ASSEMBLED BICYCLE, GIVEN THAT THE WHEELS WOULD BE IDENTICAL, IT'S EASIER AND QUITE ACCURATE TO SUBTRACT THE BB HEIGHT FROM THE WHEEL RADIUS TO DETERMINE BB DROP, don't you think?
