12T Narrow wide pulleys for Shimano Ultegra and Dura Ace - Fire Engine Red
Everyone knows the red ones are faster! Why do you think fire engines are red? Sirens and flashing lights not included.
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.
