Oversized pulleys fit the latest generation of Shimano derailleurs: Dura Ace R9100, Ultegra R8000/R8100 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.
