Why do we need them?
What would happen if I didn't put them in with a: cartridge type eg hollowtech 1 or b: outboard bearing type? hollowtech 2. Are they needed for 68 and 73mm BBs?
Why can't they make the bb the right width so you don't need them?
THANKS!

they are lucky charms, they keep the eagles away.

Well, for a small width (68mm?) BB you need them to get the same chainline as a larger width BB. For a larger width BB you need the little bit of space in case you want to add a chain device or some such malarkey, then you remove the spacer. I think.
