KOGEL 12/14T Oversized Derailleur Pulleys for Shimano 12-Speed Dura-Ace R9200.

These oversized pulleys fit the newest version of Dura-Ace R9200, Shimano’s flagship 12-speed drivetrain.

By using the standard cage on your Shimano derailleur, you will feel the benefits of reduced articulation in the chain, while retaining accurate shifting; something that has been a negative side effect of other large pulley systems.
