Wheels MFG Bottom Bracket Adapter PF30 Shimano 24mm - Black

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.

Specifically designed for installing 24 mm spindle diameter cranks (Shimano, Etc.)
in Cannondale PF30A (46mm ID, 73mm wide asymmetrical BB shell) frames without the need for any adapters.
