Notre avis

The RD-M8000 rear derailleur pulleys are genuine Shimano parts. They are replacement parts for the new Shimano XT M8000 rear derailleur.

Shimano XT RD-M8000 derailleur pulleys: enjoy smooth and quiet shifting

Shimano XT Y5RT98120 rear derailleur pulleys are genuine parts designed to replace worn pulleys on Shimano Deore XT RD-M8000 derailleurs . Over time, the teeth on the pulleys wear down, the bearings develop play and drivetrain performance deteriorates. This kit restores precise, quiet and efficient gear changes.

This set comprises a guide pulley and a tension pulley, each with 11 teeth and designed to work perfectly with 11-speedShimano drivetrains . The bearings ensure smooth rotation whilst minimising friction, thereby helping to improve the drivetrain’s efficiency.

Manufactured to Shimano ’s quality standards, these pulleys guarantee perfect compatibility with the RD-M8000-GS, RD-M8000-SGS and RD-M8050-GS (Di2 version)derailleurs . They are easy to fit as replacements for the original parts, with no modifications required.

Old worn roller, the new ones allowed to restore precision on the gear change. Be careful with the installation, the rollers have a mounting direction (Translated review)

An original pair, ideal for a very lightly used bike, as it lasts very well over time. In sustained use, there are no complaints, it's solid. For a novice to change it, they must pay attention to the direction and order of the pulleys. (Translated review)
