The Shimano Dura-Ace RD-9000-9070 Rear Derailleur Pulley Set is a precision replacement part designed to keep your Dura-Ace 9000 or 9070 rear derailleur running smoothly and efficiently. These pulleys — often called jockey wheels — guide the chain through the derailleur with minimal friction, helping deliver crisp, accurate shifting and reduced drivetrain resistance. They’re an essential service item for riders who demand continued performance from Shimano’s flagship mechanical and Di2 rear derailleur platforms.

Engineered to Shimano’s exacting standards, this pulley set features durable construction and optimized tooth profiles that promote consistent chain engagement. When installed correctly, the pulleys help maintain precise chain path alignment and reduce noise, wear, and drivetrain drag. Keeping the pulleys in good condition is especially important as they age, because worn or dirty wheels can compromise shifting quality and increase wear on your cassette and chain.

This set is compatible with both Dura-Ace RD-9000 (mechanical) and RD-9070 (Di2 electronic) rear derailleurs, making it a versatile choice for riders maintaining either version of Shimano’s high-end road drivetrain. Installation is straightforward with standard derailleur hardware, and periodic replacement as part of regular drivetrain service helps ensure your shifting stays sharp and efficient over time.
