First measure your actual shell width. Is it 70mm? Under the DS Cup, is that a spacer I see before me?

Already did this before ordering the BB. It is exactly 70mm. There are no spacers in play at all.

I have double checked the cups and they both say ITA on. I just don't understand why they are the same width as the ones used on a 68mm shell that doesn't need spacers. Clearly going to lose 2mm somewhere on the axle?

Have tried to find standard cup widths, but SRAM appear to want to keep their secrets.

Can you check if there's a spacer on the DS spindle? (between the wavy washer and the crank).

The other thing I would do is face the shell, as it look like it got paint on it, it won't make that much of a difference but worth doing anyway.

Your other option is running a Shimano hollowtech bottom bracket with an adapter to convert NDS to 22mm.

face the shell

+1 - always a good idea.

Thanks. There are no spacers anywhere - not even a wavy washer at the moment. I'll look into getting the LBS to face it.

Does anybody know if the ITA cups should be narrower than the bsa ones?
