High quality ceramic products
All the parts used in the CeramicSpeed Bearings and chains are carefully selected from the highest quality suppliers. This allows us to create the ultimate performance products, which meet the demands of competitive athletes, enthusiast riders and industry manufacturers. The CeramicSpeed products are seeking to optimise the performance of every rider, increasing their chances to the podium or upgrading their biking experience to pro.
The balls CeramicSpeed uses in the its Bearings are of very high quality and have a super smooth surface, compared to both steel balls and other ceramic balls used for bicycles. This gives the CeramicSpeed Bearings extreme impact strength, unmatched longevity and very low friction. Within the bearings, the CeramicSpeed Balls are kept in place by a reinforced polyamide cage. Balls and cages are matched (within microns) with the finest hardened steel raceways and an ultra smooth polished groove. To this, CeramicSpeed adds the optimised low-viscosity CeramicSpeed Grease and no friction seals to keep water and dirt away from the CeramicSpeed Balls.
Every single bearing is hand built in Denmark under laminar flow clean room conditions. CeramicSpeed inspects each bearing by hand four times during the building process and check our optimised chains every step of the process to ensure that all parts are matched perfectly.

CeramicSpeed Balls
All CeramicSpeed Balls are of the highest quality Grade 3 Silicon Nitride, featuring the highest achievable surface finish and roundness. The quality of the balls is what determines the performance and lifetime of a bearing. The CeramicSpeed Balls feature unparalleled impact strength, smoothness, roundness and brittleness, proven to be superior to both ceramic and steel balls typically used in the cycling components.
