Run your Shimano or FSA 24mm crankset in a BB30 frame without compromise — the CEMA SRC-BT-BB3024B interlock adaptor converts BB30 shells (OD 42mm, 68/73mm width) to accept 24mm axle cranksets via a secure interlock mechanism. Packed with CEMA's ceramic hybrid bearings, it delivers the smooth, low-friction pedalling feel that ceramic is famous for, with long service intervals to boot.
