Press Fit CeramicSpeed
CeramicSpeed is a Danish brand that specializes in high-performance ceramic bearings and drive components for various industries including cycling, automotive and industrial applications. The brand is known for its innovative and cutting-edge technology, offering products that aim to improve the efficiency, durability, and overall performance of mechanical systems. CeramicSpeed was founded in 2004 by Jacob Csizmadia, a mechanical engineer with a passion for cycling. Frustrated by the limited options for high-quality bearings in the cycling industry, Csizmadia decided to develop a superior solution. He began experimenting with ceramic materials, which are known for their low friction and high wear resistance. After years of research and development, CeramicSpeed was born.
