FAQ

What is the difference between Version 1 and Version 2 RD-6800 pulleys?

Version 2 pulleys include sealed bearings in both the guide and tension pulley wheels, providing smoother rotation, reduced chain noise, and longer service life compared to the original bushings in the Version 1 design.

How do I know when my derailleur pulleys need replacing?

Look for hooked or pointed tooth profiles, side-to-side play in the pulley when pressed, or increased chain noise that persists after cleaning and lubing the drivetrain. Replacing before bearings seize prevents cage damage.

Will these fit the Shimano 105 RD-5800 derailleur?

No. Pulley dimensions and bolt spacing vary between Shimano derailleur families. These are designed specifically for the Ultegra RD-6800 cage and are not confirmed compatible with 105 or other derailleurs.
