Product Information
Full details
The Shimano Pulley Set for the RD-5800-SS is designed for road cyclists and mechanics looking to maintain the precision and efficiency of an 11-speed drivetrain. This original replacement part restores crisp shifting performance by replacing worn-out jockey wheels with high-durability nylon components. While it is an essential maintenance item for longevity, users should ensure they are specifically servicing the short cage (SS) 105 RD-5800 derailleur to guarantee perfect mechanical alignment.

FAQs
Are these pulleys compatible with the RD-5800-GS (long cage) derailleur?
While the 11-tooth size may match, it is recommended to check the specific part number requirements for the GS cage length as spacing can vary.
Do I need to replace the chain when installing new pulleys?
It is highly recommended to inspect your chain for wear using a chain checker; if the chain is worn, it can cause the new pulleys to wear out much faster.
How often should I replace my jockey wheels?
It is generally suggested to replace them when the teeth appear sharp, hooked, or when there is noticeable side-to-side play in the wheels.
Are these pulleys ceramic?
No, these are standard Shimano replacement pulleys manufactured from high-durability nylon.
Can I use these on a 10-speed derailleur?
These are designed for 11-speed indexing; using them on other systems may result in poor shifting performance.
Troubleshooting
Excessive noise from the rear derailleur after installation
Verify that the pulleys are installed in the correct position; the guide pulley and tension pulley have specific placements.
Chain dragging or stiffness
Check that the pulley bolts are not overtightened, which can compress the bearings and prevent free rotation.

Setup, Compatibility & Care
This pulley set is strictly intended for use with the Shimano 105 RD-5800-SS (short cage) rear derailleur. Installation requires basic bicycle tools, specifically a 2.5mm or 3mm hex key depending on your specific derailleur cage hardware. When installing, ensure the directional arrow on the pulleys—if present—points in the direction of chain rotation. To maintain the life of your new pulleys, keep the drivetrain clean and apply a high-quality bicycle chain lubricant sparingly, wiping away excess to prevent dirt buildup in the pulley bearings.
