OSPW Shimano 9100 and 8000 Mounting & Maintenance
CeramicSpeed Component Maintenance GuideIt is important that you properly lubricate your bearings in order to ensure optimal performance and maximum longevity. Add oil by using the lubrication points on the back cage plate, so that oil can penetrate the bearing. Do this when you lubricate your chain, if you have washed your bike or after riding in wet or muddy conditions.
