In order to get the best performance and shifting from your OS-PW System, it is recommended to have the system installed by a professional bike mechanic.
Below are two step-by-step installation guides on how to best install the Shimano 9100/8000 OSPW System. One for the first version of the system with a stop screw, and one for the newest design with an integrated stop tower.
When travelling, please remember to dismount your entire rear derailleur with an Allen key, as the OS-PW System will not fit in most bike travel bags and could be damaged if left on.
Maintenance of CeramicSpeed OSPW Systems
Regarding the maintenance of your CeramicSpeed OSPW Oversized Pulley Wheels System, it 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.
