12/14T Oversized pulleys for Shimano road derailleurs (preproduction samples)
Looking for that badass oversized pulley look, but without affecting shifting accuracy? These pulleys fit on your stock cage, no need to rebuild the derailleur.
These 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 and the narrow wide tooth profile, you will get the benefits of reduced articulation in the chain, while retaining accurate shifting. Something that has been a negative side effect of running large pulley systems.
If you are looking for the best pulleys to fit the previous generation Dura Ace (9000) and Ultegra (6800), please have a look at our 12 tooth road pulleys.
***please note these are pre production samples presented at an introduction price, we have a limited amount available. They are different from the production in the lower pulley, which has narrow wide teeth on the bottom pulley. Production will be with a smooth profile.
Ball bearings are wear items, similar to the chain on your bicycle. While we went out of our way to present you with the best possible product, your Kogel Bearings do require some maintenance and a new seal kit from time to time. Please download this service document from our manuals section for a step by step on how to keep your bearings running smoothly.
