How do I know the cup is fully seated?

Setup, Compatibility & Care

Before starting, ensure your frame's bottom bracket shell is clean, debris-free, and lightly greased according to your frame manufacturer's instructions. Select the correct adapters from the included PF46 kit to match your specific bottom bracket standard. Thread the tool through the bottom bracket shell, ensure the cups are oriented correctly, and tighten the handles slowly. For maintenance of the tool itself, keep the threads clean and lightly greased to ensure smooth operation. Store in a dry, cool environment to prevent oxidation of the metal surfaces.
