Shimano XTR RD-M9100 Tension and Guide Pulley Set

Shimano XTR RD-M9100 Tension and Guide Pulley Set If the bearings or pulley wheels on an expensive; high-performance Shimano XTR 12-speed rear derailleur start to bind or wear then this official Shimano RD-M9100 Tension and Guide Pulley Set is just the thing to bring a new lease of life into the drivetrain. Both the guide and tension pulleys; so upper and lower in layman’s terms; are included and promote smooth and friction-free spinning in any gear thanks to their precision sealed bearings. They are compatible with long and medium cage versions of the XTR RD-M9100 rear derailleur; as well as the XTR RD-M9120 variety.
