Kogel Hybrid 12/14T Oversized Derailleur Pulleys for Shimano

Notify me when this product is available:

12/14T oversized derailleur pulleys for Shimano Dura Ace R9100, Ultegra R8000 and 105 R7000

Want to run that oversized pulley look, but without rebuilding your derailleur? These pulleys fit on your stock cage.

Oversized pulleys fit the latest generation of Shimano derailleurs: Dura Ace R9100, Ultegra R8000 and 105 R7000.

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 many large pulley systems.
