Does the Shimano 105 RD-5800 Pulley Set Restore Your 11-Speed Road Shifting?

The Shimano 105 RD-5800-GS pulley set is the OEM replacement for both the guide and tension pulleys in the 105 RD-5800-GS 11-speed road rear derailleur, with an upper guide pulley featuring enlarged teeth for improved chain control and more precise lateral chain guidance across the cassette. The nylon body construction with metal bushings keeps friction low and operation quiet, and the proprietary tooth geometry matches the cable pull geometry of the RD-5800 cage exactly. When worn pulleys introduce chain rattle, hesitation on upshifts, or loss of indexing precision, genuine Shimano OEM pulleys are the correct restoration.

Includes guide pulley (upper/G) and tension pulley (lower/T). Compatible with Shimano 105 RD-5800-GS and RD-R7000-GS 11-speed road rear derailleurs. MPN: Y5YE98090.

FAQ

Is this pulley set compatible with the newer RD-R7000?

Yes. The Y5YE98090 is compatible with both the RD-5800-GS and the RD-R7000-GS, the 105 5800-series successor. This makes it the correct OEM replacement for both generations of 105 11-speed GS cage derailleurs.

How do I know when my 105 pulleys need replacing?

Look for rounded or hooked tooth profiles on the guide pulley, lateral play when pressing the pulley body sideways, or chain noise and hesitation on downshifts that persist after a full drivetrain clean.

Will this fit the SS short cage version of the RD-5800?

This listing is for the GS medium/long cage version. The SS short cage uses a different pulley set. Confirm your cage type before ordering.

Best For
