The BlackBearing C BB30 bottom bracket allows you to fit a DUB-axle crankset to a BB30-standard frame. Fitted with ceramic bearings, it offers lower friction, a longer service life and greater stiffness to optimise your bike’s mechanical performance.
This bottom bracket is designed with two machined aluminium cups that screw into one another for better alignment, reducing creaking, optimising smoothness and efficiency, extending the life of the bearings, and making installation and removal easier.
