The benefits are super low friction, better power transfer and increased bearing life. During the building process, we check each bearing four times by hand to ensure that all parts are matched perfectly. CeramicSpeed Balls are 400% smoother, 128% harder and 58% lighter than standard steel bearings normally used in the bicycle industry. When comparing the CeramicSpeed Balls with other ceramic balls in the industry, you will find that the CeramicSpeed Balls are 15% harder, take 99% higher loads and are 100% smoother.
