Rear derailleur hanger Shimano road 105 RD-R7000 11v - Y3F398010

Shimano ’s Y3F398010 rear derailleur pulleys are genuine parts specially designed for Shimano ’s 105 RD-R7000 11-speed derailleurs. Essential to the proper functioning of the drivetrain, they ensure precise chain guidance and play a direct role in the quality of gear changes, the smoothness of pedalling and the reduction of operating noise.

This kit includes a guide pulley and a tension pulley, both featuring 11 teeth, enabling you to restore the original performance of a derailleur worn down by kilometres of use. Compatible with the RD-R7000-SS (short cage) and RD-R7000-GS (medium cage) versions, these pulleys offer a simple and cost-effective solution to extend the lifespan of your drivetrain.

Manufactured to Shimano ’s quality standards, they ensure smooth chain rotation and help protect both the cassette and the chain by minimising excessive friction. Replacement is recommended when the teeth show significant wear or when gear changes become less precise.

Ideal for maintaining a road bike fitted with the Shimano 105 R7000 groupset, these pulleys restore a quiet, high-performance and reliable drivetrain for both everyday use and competition.
