Troubleshooting
Audible creaking sound while pedaling
Remove the crankset, clean the spindle and bearing interfaces, apply fresh grease, and verify that the press-fit cups are still fully seated.
Lateral play or movement in the crank arms
Check your CINCH spacer configuration. You may need to add or adjust spacers to achieve a secure, zero-play fit.

Setup, Compatibility & Care
Installation requires a standard bearing press tool to ensure the cups are seated evenly into your frame's PF30 shell. It is highly recommended to use a thin layer of appropriate anti-seize or bearing retention compound on the cup surfaces to prevent future creaking. If you find your crankset has lateral play, you must utilize the RaceFace CINCH spacer kits to correctly take up the gap. Regularly inspect the unit for signs of contamination after wet, muddy rides, and ensure your spindle is clean and lightly greased before re-inserting it into the bottom bracket.
