Shimano Ultegra RD-6700-A 10-Speed Rear Derailleur Pulley Set - ver.2
What Is the Shimano Ultegra RD-6700-A Pulley Set and When Do You Need One?
The RD-6700-A ver.2 pulley set is the replacement tension and guide pulley assembly for Shimano's 6700-series Ultegra 10-speed rear derailleur. Pulleys are wear items, and over time the teeth profile wears down and the bushings or bearings develop play, which manifests as chain slap, inconsistent chain tension, and degraded shift quality even when the rest of the drivetrain is in good condition. The ver.2 designation indicates a revised pulley geometry compared to the original RD-6700 pulley set, with updated tooth profiling for improved chain engagement and retention. Each pulley in the set functions differently: the guide pulley (upper) is the shift-assist pulley that guides the chain across cassette cogs, and the tension pulley (lower) maintains chain tension through spring-loaded derailleur cage movement. Replacing both at the same time ensures consistent performance across the cage assembly.
The pulley set is a direct fit for the Ultegra RD-6700-A rear derailleur and is compatible with Shimano 10-speed road chains and cassettes in the Ultegra, 105, and Tiagra tiers. Replacement is a straightforward workshop procedure requiring only basic tools and is significantly more cost-effective than replacing the entire rear derailleur when the cage and hanger are still in good condition. For riders running Shimano Ultegra 6700-series 10-speed drivetrains with worn, wobbly, or noisy pulleys, the RD-6700-A ver.2 pulley set restores derailleur performance to spec at minimal cost.
