PF30 Technical Info
PressFit-30 (PF30) bottom brackets are a separate component pressed directly into the frame. 30mm bearings (6806) are pressed into cups and the cups then pressed into the frame. Originally designed for 30mm spindle cranks, 24mm (Shimano, FSA, etc.) or 22/24mm (GXP, SRAM, etc.) spindle cranks can be used with the PF30 system when using adapters.
