High quality ceramic products

All the components used for the CeramicSpeed bearings and chains have been carefully selected by CeramicSpeed technicians to guarantee durable and high quality products, this allows us to design and create the best products on the market capable of satisfying the needs of the best athletes in the world but also the desires of the most dedicated enthusiasts.
The CeramicSpeed products allow the performance of every cyclist to be improved, increasing their chances of getting on the podium but at the same time improving their sensations while riding.
The spheres used for CeramicSpeed bearings are composed of high quality ceramic which allows for the creation of an ultra-smooth surface with a significantly lower friction coefficient compared to the classic steel or ceramic spheres currently used on bicycles all over the world. These characteristics allow CeramicSpeed bearings to offer incredible resistance to impacts but at the same time an uncommon longevity.
Ceramic balls and their polyamide cage are made to match (within a micron difference) with the best rings steel seals equipped with polished surfaces with a low friction coefficient, to complete and protect its bearings CeramicSpeed uses a specific low viscosity grease and anti-friction seals to keep water and dirt away from the ceramic balls.
To guarantee the best performance each bearing is produced in Denmark in locations with regulated ventilation and isolated from any type of contaminated agent and inspected four times during the production process to ensure that all components fit together perfectly.
The quality of the ceramic spheres determines the performance and longevity of a bearing, for this reason all CeramicSpeed balls are made of grade 3 Silicon Nitride, which allows the highest standards to be achieved in terms of surface finish and roundness of the balls.
CeramicSpeed balls guarantee impact resistance, surface uniformity and unparalleled roundness, capable of standing out and offering incredible performance when compared to the classic ceramic or steel spheres used for many components currently on sale.
