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.

If you are looking for the best pulleys to fit the previous generation Ultegra (6800), please have a look at our 12 tooth Shimano road pulleys.

For Dura Ace 9000 and Sram road short cage derailleurs, have a look at our 11 tooth derailleur pulley set.

  1. Remove the Old Pulleys: Shift to the smallest cog, remove the rear wheel for better access, and use Allen keys to remove the bolts securing your current pulleys.
  2. Set Up Your New Pulleys: Check the directional arrows on your Kogel Pulleys for correct orientation and attach them to your derailleur cage, starting with the lower pulley.
  3. Align and Secure: Properly align the new pulleys within the derailleur. Use a torque wrench to tighten the bolts to the recommended settings.
  4. Check and Adjust: Reinstall the rear wheel, manually run the chain to ensure smooth movement, and adjust as needed for clean operation over the pulleys.
  5. Test Ride: Conduct a short test ride to ensure everything functions correctly, listening for any unusual sounds and verifying smooth shifting across all gears.

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::

  1. Clean - feels like it’s spinning effortlessly in fresh grease
  2. Dirty - feels like it’s spinning with some grit in the grease
  3. 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.
