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.

This model will fit on Dura Ace R9100 and Ultegra R8000 series derailleurs. This includes mechanical and Di2 as well as short (SS) and medium (GS) cage lengths.
