Compatible with the Dura Ace CS 7900, Ultegra CS 6700, CS 6600 and 105 CS 5600 10-speed cassettes.

Shimano manufactures its own sprockets with different shift profiles for almost every cassette configuration. Therefore, the replacement sprockets and sprocket blocks are only perfectly matched in the specified configuration. If you mix sprockets from different configurations, shifting performance may deteriorate significantly.

You can order the replacement sprockets listed below using the respective item numbers in our webshop.
