Shimano RD-R8150 Ultegra Rear Mech Pulley Set
- Suitable for Ultegra RD-R8150
- Improve shifting performance
- Genuine Shimano replacement part
The Shimano RD-R8150 Ultegra Rear Mech Pulley Set helps you keep your rear derailleur running smoothly by replacing worn guide and tension pulleys. You use it to maintain accurate shifting through two pulley wheels built to match the RD-R8150 design, giving you consistent chain control.
Here are the key features of this pulley set:
• Guide Pulley Design: This pulley uses Shimano’s engineered tooth profile and sealed bearing layout, which reduces friction and keeps chain movement steady, helping you maintain dependable shifting under everyday road use.
• Tension Pulley Construction: This pulley features a shaped tooth pattern and a durable polymer body that manages chain tension with precision, supporting quiet operation and a stable chain path during each shift.
• Genuine RD-R8150 Fitment: This set is built to match the exact fit and spacing of the RD-R8150 rear derailleur, ensuring you install the pulleys without adjustment issues and achieve the performance the derailleur is designed to deliver.
Use this set to restore clean, controlled shifting when your original pulleys show signs of wear, which helps you avoid rough or inconsistent gear changes. Keeping fresh pulleys in your drivetrain supports crisp indexing and reduces unwanted drivetrain noise during regular road riding. This is a practical addition to your maintenance routine when you want a smooth and reliable derailleur setup on your road bike.

This also means an express delivery service is unavailable. We strive to despatch bikes within 3-5 working days. Please note this may change over school holidays and the festive season (November/December). For more information on the process please visit our pre-build page.
