Shimano Deore 11-Speed Jockey Wheel Set

The Shimano Deore 11-speed jockey wheel set is a replacement for the rear derailleur, consisting of two black wheels that tension and guide the chain. The wheels are designed for 11-speed drivetrains and are compatible with the Deore RD-M5100 (1x11) rear derailleur.

Before buying, check your rear derailleur: the set is compatible with the Deore RD-M5100 but not the Deore RD-5120, which is designed for 2x11/10 and 1x10 configurations. The manufacturer code Y-3HL98010 helps you confirm the exact part. If your drivetrain is 1x11, the set is the right choice for the RD-M5100 rear derailleur.

Founded in 1921 in Sakai, Japan, by Shozaburo Shimano, Shimano is still based in the same city today. For cyclists, it makes drivetrains, brakes, wheels, pedals and cycling shoes. Its history in bicycle components began with the production of freewheels in 1922.
