Upgrade your GRX RD-RX810 rear derailleur with Shimano’s Tension and Guide Pulley Set. These genuine replacement parts are finished in black to complement a range of setups and are designed to restore smooth, responsive gear movement without altering your drivetrain geometry.
This set focuses on the tension and guide pulleys that riders rely on for consistent chain tracking. It’s engineered to work seamlessly with the RD-RX810, helping you maintain clear shifts across varied terrain—from city streets to longer rides on mixed surfaces.
The set includes the tension pulley and the guide pulley, designed to fit the GRX RD-RX810 rear derailleur. While installation is straightforward for riders with basic bike maintenance skills, refer to your derailleur model and torque specifications if you’re unsure.
Keep the pulleys clean and lightly lubricated to reduce friction. After mud and rain, wipe away grit before re–lubricating to extend life and maintain smooth operation.
