The confusion persists with different brands simply because so few tech's have knowledge of a consistently reliable standard method of reference.

If someone substituted an ISO or Campy bb spindle for the proper Dura-Ace part, it would effectively shorten each end of the spindle by at least 2mm (between 2 and 3 mm each end).

The question I have is who wrote your chart?
