FSA BB30 micro adjust spacers (Shim)

BB30 micro adjust spacers (Shim)

The spacers are for adjusting any "side to side play". The spacers are not required when the frame is manufactured to the exact BB30 specification. The BB30 specification calls for extremely accurate manufacturing and there may be instances when the standard is not met. These spacers only need to be used when the BB30 tolerances are not met, and are to help customers use our BB30 cranks where there may be tolerance issues.
