The PF30 standard uses a wider 46mm shell for increased frame stiffness. Our PF30 BB is engineered specifically for it — Grade 3 silicon nitride angular contact bearings with DLC-coated races press into the larger shell with precision-molded nylon cups that absorb vibration and eliminate creaking. The wider bearing spacing improves load distribution and lateral stiffness. Compatible with 30mm spindle cranks, adapters included for 24mm.
