    what it says in the instructions.

    no BB mount items then one each side.

    I seem to recall that mine needed a single 2.5mm spacer between each cup, i.e. one on each side. Many external bearing MTB BBs are designed to fit 73mm shells with no spacers, and for 68mm, you need to make up 5mm overall.
