Ceramicspeed Single Bearing 61902C

CERAMICSPEED ball bearing 

The bearings from the Danish company CeramicSpeed represent the absolute high-end solution for all racers who place the highest value on the lowest friction with the best power transmission. This makes you faster and more effective with the same effort.
The CeramicSpeed balls are 15 % harder than those of the competition and can absorb considerably more force. They also have an incredibly smooth surface, reducing rolling resistance to a minimum. All these improvements have resulted in a 6-fold increase in service life.

Coated
In contrast to the already high-quality standard bearings from CeramicSpeed, the “coated” version has a wafer-thin protective layer applied to the bearing rings. This makes the latter even harder, extends their life cycle by a further 60 % and reduces rolling resistance even further.

CeramicSpeed uses only the best materials and the latest technologies in production to ensure the highest possible quality at all times. All products are handmade in Denmark.
No hydraulic presses are used during assembly. Manual assembly eliminates manufacturing tolerances and guarantees a perfect fit every time. So that you really only install the best on your bike.

The makers of CeramicSpeed have great confidence in their products and give you a lifetime guarantee on this bearing.
