Does the Shimano Dura-Ace RD-7900 v2 Pulley Set Restore Clean Shifting?

The Shimano Dura-Ace RD-7900 Version 2 pulley set is the OEM replacement for both the guide and tension pulleys in the Dura-Ace RD-7900 10-speed road rear derailleur. The Version 2 designation indicates sealed bearings in both pulley wheels, an upgrade over the original version that delivers quieter rotation and longer service intervals. When worn pulleys introduce chain noise at the derailleur cage, hesitation across the cassette, or visible shark-fin tooth wear, swapping in genuine Shimano OEM pulleys restores the precise lateral chain control the RD-7900 cage was engineered for.

Includes both the upper guide pulley and lower tension pulley. Designed specifically for the Shimano Dura-Ace RD-7900 10-speed rear derailleur. Version 2 pulleys are the current production spec and are backward compatible with earlier RD-7900 cage configurations. A cost-effective service part for maintaining a high-quality 10-speed road build.
