Benefits of these bearings: 10 % less friction than in an all steel configuration. Cup and cone system. In hubs without cage/retainer the friction will be reduced. Silicon nitride balls with less friction than steel balls and are 60% lighter than steel. Extremely wear resistant. The ceramic material is much harder than the hardest of bearing steels. Safe operation even when using low amounts of lubricant. Minimal risk of seizure. Tolerant to dirt and dust. Resistant towards corrosion. Together with special seals and lubrication the friction in ceramic bearings can be some 20-30 times lower than steel bearings with standard friction seals and standard lubrication. Higher stiffness from the silicon nitride balls increases stiffness in the bottom bracket and hubs. Long lifetime with approximately 20 times longer lifetime than steel bearings.
