Royal Blue 12 tooth narrow wide pulleys for Shimano Ultegra and Dura Ace
Royal Blue was a color reserved for Kogel Bearings sponsored athletes, but it is available to us mere mortals now.
These pulleys will fit perfectly on your Shimano Dura Ace 9000 and Ultegra 6800 derailleurs. The narrow wide tooth profile on the top pulley helps to retain shifting accuracy by pushing every link of the chain.
Road seals only. If you are looking to equip your gravel bike, please select the Shimano MTB version.

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.
Kogel Bearings strives for best-in-industry product support. Our hybrid and full ceramic bearings are covered under our 1+1 year warranty, which guarantees that we will keep you on the road for two years, pending on annual bearing service. Read more about our philosophy in this blog post.
