PF30 with outboard bearing BB for use with 29mm spindle SRAM DUB compatible cranksets. 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.
