Ceramic mtb bearings.
The silicon nitride used in kogel ceramic bearing balls has a set of material properties making them perfect for bicycle wheel bearings.
A ceramic hybrid bearing has steel races with ceramic balls and a full ceramic bearing has ceramic races and balls.
And when we talk about the peace of mind provided by ceramic bearings we mean that the next time you find a stream or areas with water in the middle of your path you will not have to stop to think about the time you will have to spend later on.
Additionally silicon nitride does not deform under load keeping contact points with the bearing races to a minimum.
The material can be polished smoother than any metal reducing friction and wear.
Miniature full ceramic and ceramic hybrid bearings are particularly well suited to both competitive and recreational bicycle applications.
