Does the Shimano GRX RD-RX810 Pulley Set Restore Quiet Gravel Shifting?

The Shimano GRX RD-RX810 tension and guide pulley set is the OEM replacement for both pulleys in the GRX RD-RX810 11-speed gravel rear derailleur, featuring precision sealed bearings in both the guide and tension pulley wheels for smooth, low-friction chain operation. The asymmetric pulley design reduces chain noise -- an important detail for gravel riders who spend long hours on mixed surfaces where drivetrain buzz is amplified by rough terrain. When worn pulleys introduce hesitation, noise, or lateral chain wandering, this genuine Shimano pulley set restores the precise chain control the RD-RX810 was designed to deliver.

Includes guide pulley (upper/G), tension pulley (lower/T), covers, and low-maintenance bushings. Compatible with Shimano GRX RD-RX810 and RD-RX815 rear derailleurs. Guide pulley bolts are sold separately. MPN: Y3GE98010.

FAQ

Will this pulley set fit other Shimano rear derailleurs?

This set is designed specifically for the Shimano GRX RD-RX810 and RD-RX815. Pulley dimensions and cage configurations vary across derailleur models -- confirm fitment before ordering for any other derailleur.

Do the guide pulley bolts come included?

No. Guide pulley bolts are sold separately. Reuse the existing bolts from your derailleur cage unless they are damaged.

How do I know if my GRX pulleys need replacing?

Signs include chain noise that persists after cleaning, hesitation or skipping during shifts, hooked tooth profiles on the pulley teeth, or lateral play when pressing the pulley body sideways.

Best For

Gravel cyclists servicing a Shimano GRX RD-RX810 or RD-RX815 rear derailleur with worn pulleys who want genuine OEM sealed-bearing replacements to restore quiet, precise 11-speed shifting.
