CeramicSpeed ceramic balls are rounder, harder, smoother, lighter and more resilient than steel balls and ceramic balls from other manufacturers. CeramicSpeed ceramic bearings therefore last 3 to 5 times longer than other commercially available bearings. All CeramicSpeed bearings are manufactured by hand in Denmark under clean room conditions and are subject to a strict four-stage control procedure. Among other things, the size of the ceramic balls is checked down to the thousandth of a millimetre. Tests are then carried out in the laboratory or preferably by professionals in training and competition. CeramicSpeed bottom brackets guarantee you the lowest possible friction, optimised power transfer and maximum durability and also help you save watts and reach the finish line faster. It’s not about seconds, it’s about minutes!
