Convert PF30 to BSA (English Thread); Press it into your frame and then thread in your external cups of choice. Made from alloy instead of flimsy plastics, so it is more durable and less prone to deforming during installation and use.This adapter does NOT mean the frame is ready to accept a crankset. It means it has been converted to a BSA frame, and now you can use a BSA BB and crankset on the frame.
