OK so my cranks started to move out and in on me,like i will make them as tight as possible and they still move .have tried spacers and nothing. i cant get a warranty on them cause i bought them used like one year ago does anyone know of a way to fix this? any help will be useful thanks. i dont come on here much so just email me if possible my email is email@example.com
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.
