Ball bearings
Explanation:
Friction is a phenomenon which resists motion when an object is rubbed against another. Static friction is between two objects that are not moving. Sliding friction is between two objects when one or both are sliding against each other. Sliding friction is lesser than static friction. Rolling friction is between two objects where one or both of the surface is circular. Rolling friction is less than sliding friction.
Ball bearings is the device which is used between the hubs and axles of bicycle wheels to reduce friction. Ball bearings reduce friction because they convert sliding friction to rolling friction.
