FAQ

What does Version 2 mean for the RD-6700 pulley set?

Version 2 refers to the sealed bearing upgrade in both the guide and tension pulley wheels, replacing the original bushing design with sealed bearings for quieter operation and longer service intervals.

How do I know my RD-6700 pulleys need replacing?

Symptoms include shark-fin tooth profiles on the pulley teeth, lateral play when pressing the pulley sideways, or persistent chain noise after cleaning and lubing. Replace before the bearings seize to protect the cage.

Will these pulleys fit in any other Shimano rear derailleur?

These are designed specifically for the Shimano Ultegra RD-6700-A. Pulley bolt spacing and cage dimensions vary across derailleur models and generations. Confirm fitment before ordering for other derailleurs.
