Remember to lubricate your CeramicSpeed bearings properly in order to obtatin the optimal performance and the maximum longevity. When lubricating the chain, when washing your bike or after riding in wet/muddy conditions, it is recommended to lubricate the system’s bearings. To do so, add oil into the lubrication points on the back cage plate, so that oil can penetrate the bearing.
