This ceramic bottom bracket for the SRAM DUB crank generation fits all frames with a BB30 bottom bracket shell. Due to the reduced frictional resistance of the ceramic balls, you can pedal more efficiently and thus save a lot of energy. The robust seals of the DUB bearing generation ensure a long service life and silky smooth running.
