   OK I'm feeling a little challenged - exactly how many spacers do I need to put on my BB?

   It's a 68mm case and I'm running regular 3x9 setup with no cain devices on a 07 Rockhopper.

   68mm BB is 2 on the drive side one on the other side,
   73mm BB one on the drive side.

   3 spacers with 1 per side and the third one on whichever side gives you the best chainline
