Shimano Y3F398010 rear derailleur pulleys are original parts specially designed for Shimano 105 RD-R7000 11-speed derailleurs. Essential to the smooth operation of the transmission, they ensure precise chain guidance and contribute directly to the quality of gear changes, smooth pedalling and reduced operating noise.

This kit includes a guide pulley and a tension pulley, both with 11 teeth, to restore the original performance of a derailleur that has been worn down by miles of use. Compatible with the RD-R7000-SS (short clevis) and RD-R7000-GS (medium clevis) versions, these rollers are a simple, cost-effective solution for extending the life of your drivetrain.

Manufactured to Shimano quality standards, they guarantee smooth chain rotation and help protect the cassette and chain by limiting excessive friction. Replacement is recommended when teeth show marked wear or when gear changes become less precise.

Perfect for maintaining a road bike equipped with the Shimano 105 R7000 groupset, these rollers will ensure that your drivetrain is silent, efficient and reliable in everyday use as well as in competition.
