External BB, why do I need spacers?

If I am not running a front mech on a 73mm bb shell

Re:

If it is a 68mm shell you will need spacers as it has a fixed length axle and you need to get the right spacing to get the compression

Re:

The shell is 73mm

Re:

I think you need 2 on a 68, and 1 on a 73, none if you run a chain device or bb fitting front mech

Re:

Ah yeah, just read no spacers if running e type bb
