Turbo-charge your bike with ceramic bearings. Compared to steel bearings, Ceramic Speed Silicon Nitride (Si3N4) bearings reduce friction, decrease power loss, reduce weight and lengthen service life. They are also less susceptible to dirt, dust and poor lubrication. Select English (68mm) or Italian (70mm) threading.
