Shimano Dura-Ace RD-7900 10-Speed Rear Derailleur Pulley Set - Version 2
What Does the Shimano Dura-Ace RD-7900 Pulley Set Replace?
The RD-7900 Version 2 pulley set is the OEM replacement tension and guide pulley assembly for the Shimano Dura-Ace 7900 10-speed rear derailleur. When pulleys wear down from extended use, the most common symptoms are increased drivetrain noise, imprecise shift indexing, and chain skipping under load. Replacing the pulley set with the correct OEM unit restores the derailleur to factory specification without requiring a full derailleur replacement. The Version 2 designation indicates this is the updated production revision for the RD-7900, with improved bushing tolerances over the original release.
Both the tension pulley and guide pulley are included as a matched pair, ensuring the correct tooth profile and bushing geometry for smooth chain articulation through the cage. Using non-OEM pulley replacements on a Dura-Ace derailleur risks compromising shift precision and chain retention, particularly at the extremes of cassette range. The RD-7900 was Shimano's flagship 10-speed road derailleur and remains in widespread use on older high-end road bikes. For riders maintaining or restoring a 7900-generation Dura-Ace drivetrain, this pulley set is the correct OEM service part.
