Shimano GRX RD-RX810 Rear Derailleur Tension and Guide Pulley Set
What Is the Shimano GRX RD-RX810 Pulley Set a Replacement For?
The GRX RD-RX810 tension and guide pulley set is the OEM replacement jockey wheel assembly for the Shimano RD-RX810 rear derailleur, used in Shimano's GRX 11-speed gravel groupset. The set includes both the upper guide pulley (which positions the chain entering the derailleur cage) and the lower tension pulley (which maintains consistent chain tension through the full range of cassette gears). These pulleys are serviceable parts that wear over time, particularly under the abrasive conditions of gravel riding where grit and sand accelerate bearing and tooth wear more than typical road conditions would.
Replacing worn pulleys restores accurate chain tracking, reduces drivetrain noise, and prevents the chain skipping or hesitating that happens when jockey wheel teeth are rounded off. The RD-RX810 uses Shimano's long-cage gravel derailleur design with a wider tooth profile on the pulleys to handle the wider range cassettes common in 1x11 GRX builds. Using OEM Shimano pulleys ensures the correct tooth count, bearing clearance, and cage geometry are maintained, which matters for consistent RD-RX810 shifting performance. This pulley set is a direct drop-in replacement requiring no modifications to the derailleur cage. A standard Phillips screwdriver is all that is needed for installation alongside the included pulley bolts.
