BB30a-24 Ceramic Bottom Bracket for Shimano Cranks
Cannondale BB30A bottom bracket system applies a 73mm wide bottom bracket shell with inner diameter 42mm. The BB30A system is very similar to the BB30 standard but the frame bottom bracket shell is 5mm wider on the non-drive side. If you are aiming to run a 24mm Shimano or 22-24mm SRAM GXP spindle crankset on a BB30A frame shell, you will need this BB30A-24 bottom bracket for the conversion.
