These ceramic cups are for Campagnolos over-torque cranks and frames that have a BB30 bottom bracket.
The deep groove ball bearings with USB (Ultra Smooth Bearings - ceramic) guarantee extreme ease of movement due to the absolutely smooth surfaces and the resulting reduced friction. Comparative tests have shown that the USB bearings are 50% smoother than standard bearings. In the development, low weight, reduction of energy loss and increased corrosion resistance were not disregarded
