Oversized pulleys fit the latest generation of Shimano derailleurs: Dura Ace R9100, Ultegra R8000/R8100 and 105 R7000.
By using the standard cage on your Shimano derailleur, you will feel the benefits of reduced articulation in the chain, while retaining accurate shifting. Something that has been a negative side effect of many large pulley systems.
Switching to an oversized set might require to install a longer chain.Here is a video explaining how to get it just right.

What warranty does Kogel offer for their ceramic derailleur pulleys?

How can I tell if my derailleur pulleys need servicing?
Periodically check the bearings in your pulley wheels, especially after wet or muddy rides. Remove the dust covers, wipe away any dirt or contaminated grease and see if the bearings spin freely.
The bearing will fall somewhere between these three conditions::
- Clean - feels like it’s spinning effortlessly in fresh grease
- Dirty - feels like it’s spinning with some grit in the grease
- Dry - feels like it’s spinning effortlessly, but it’s making more noise than usual
If they feel gritty, here is a link to the best practice in pulley service.
A good habit to develop is cleaning your pulleys each time you clean your chain. While you are cleaning your chain, use the same degreaser and a rag or cotton swabs to clean off your pulleys; and hit the chain rings while you’re at it.
Remember: a clean bike is fast bike.
Can ceramic pulleys fit all types of bikes?
While they wide wide compatibility, it's crucial to check specific sizes and configurations for your bike's drivetrain system.
