Shimano Ultegra Rear Derailleur Pulley

This set is specifically designed for 11-speed Shimano road drivetrains. If you are running an 11-speed Ultegra or compatible Shimano rear derailleur, these pulleys will fit perfectly.

Yes, the package comes with both the guide pulley and the tension pulley, which is everything you need to replace the worn components in your rear derailleur cage.

The plastic construction is intentional. It helps dampen chain noise and reduces friction against the chain, resulting in a quieter, smoother ride compared to metal alternatives.

No, these pulleys feature sealed bearings, which are designed to be low-maintenance. They are protected from the elements and do not require periodic lubrication.

You should check your pulleys when you replace your chain or cassette. If the teeth look sharp or pointed rather than flat-topped, or if there is noticeable side-to-side play in the pulley, it is time for a replacement to ensure crisp shifting.
