Shimano Dura Ace CS-R9100 Cassette 11-speed - silver

The new DURA-ACE is the answer to the question posed by many professionals and ambitious amateurs as to whether and how the current, already immensely high level of performance could be increased even further. Every single DURA-ACE R9100 component is designed to work as efficiently as possible with all the other components in the system. This clearly demonstrates the core of Shimano's philosophy of components developed as a system. The result is SYSTEM SUPREMACY - the superiority of the system over the sum of its parts.

With SHIMANO's rider-adjustable cassette sprockets, the DURA-ACE R9100 enables gear combinations that can be tailored to your riding style and the terrain of your choice. The lightweight 11-speed cassettes are available in different sprocket combinations. Fast, precise and smooth shifting in all situations is guaranteed.
