Our best solution for replacing OEM PF30 bottom brackets or for new bike builds. The two machined aluminum cups thread together keeping the bottom bracket stable in the frame, increasing bearing life, and simplifying maintenance. This means no more creaking, smoother operation, longer bearing life, and really quick bearing replacement.
