Does the Shimano Ultegra RD-6700 Pulley Set Restore Your 10-Speed Shifting?

The Shimano Ultegra RD-6700-A Version 2 pulley set is the OEM replacement for both the guide and tension pulleys in the RD-6700-A 10-speed rear derailleur, featuring the Version 2 upgrade of sealed bearings in both pulley wheels for quieter chain operation and longer service life between replacements. Worn pulleys that introduce chain rattle, hesitation, or visible tooth wear are the most common cause of deteriorating 10-speed shifting performance -- genuine Shimano OEM pulleys restore the lateral chain control the RD-6700 cage was engineered to deliver.

Includes both the upper guide pulley and lower tension pulley. Designed specifically for the Shimano Ultegra RD-6700-A 10-speed rear derailleur. Version 2 is the current production spec with sealed bearings as the upgrade over the original bushing design.
