The Rotor Press Fit 4624 Bottom Bracket is designed to do one thing—mate your Press Fit 30 BB shell to your 24mm-spindle cranks. There are variations for Shimano MTB and road cranks, as well as SRAM GXP MTB and road cranks. The Shimano version will also likely work with most FSA cranks, but double check your spindle compatibility before ordering.
The 4624 uses sealed, stainless steel bearings for a long life and smooth rolling. These bearing cartridges are housed within the bottom bracket's aluminum shell—no plastic press-fit adapters here.
