I'll put it here first and e-mail you if you don't see it and respond.

Double-check all of the troubleshooting tips in the Race Face Diabolus PDF:

It sounds like you did the spacer route. Are you lock-titing the drive-side bolt? Did you get the extra non-drive-side spacer or the preload elastomer with the BB and crank?

If none of this works, I would begin to suspect the outer dust seal(s) on the BB cups. If they're ground up or missing, that could loosen up the tolerances. Looks like Race Face has a similar dust-cap set to FSA (which I thoroughly detest) and may be the source of your clearance issues.

external bearings.
