Shimano Ultegra RD-6800 11-Speed Rear Derailleur Pulley Set: Version 2
What Is the Shimano Ultegra RD-6800 Pulley Set and When Should You Replace It?
The RD-6800 ver.2 pulley set is the replacement tension and guide pulley assembly for Shimano's 6800-series Ultegra 11-speed rear derailleur. Pulleys wear gradually over time, with symptoms including chain slap under load, a wobbly or loose pulley wheel when spun by hand, visibly shark-finned tooth profiles on inspection, and degraded indexing that persists after cable tension adjustment. The ver.2 designation reflects an updated tooth geometry compared to the original RD-6800 pulley set, with revised profiling for improved chain engagement and reduced noise. The set includes two functionally distinct pulleys: the guide pulley (upper jockey wheel), which assists chain movement across cassette cogs during shifting, and the tension pulley (lower jockey wheel), which maintains chain tension through the derailleur cage's spring-loaded movement. Replacing both simultaneously ensures consistent performance and avoids mixed wear across the cage assembly.
The pulley set is a direct fit for the Shimano RD-6800 Ultegra 11-speed rear derailleur and is compatible with Shimano 11-speed road chains and cassettes across the Ultegra, 105, and Dura-Ace 11-speed tiers. Replacement is a simple workshop task requiring only a 3mm hex key and a Phillips screwdriver, and the cost of replacement is a fraction of a full derailleur replacement when the cage and hanger remain in good condition. For riders running Shimano 6800-series Ultegra 11-speed drivetrains with worn or noisy pulleys, the RD-6800 ver.2 pulley set restores derailleur performance to spec efficiently and affordably.
