Shimano Dura Ace CS-9000 Cassette 11-speed

Perseverance makes a driver to the winning driver - 11-speed drive system of the latest generation. For the new Dura Ace 9000 series Shimano has evolved each system component, used to create one of the most innovative component group sets of all time.

One of the outstanding results of this new development is the variety of transmission possibilities, corresponding to the already known "rider tuned" concept. The new 11-speed drive allows each driver to "tune" the bike for each specific application by various gradations.

Corresponding the Rider-Tuned system, the Dura Ace CS-9000 offers a number of options for different riders and situations. The new 11-speed cassettes are available in a wide range of gear ratios, including a wide transmitted 11-28T cassette - a real all-round cartridge - available. Smooth and fast gear changes are guaranteed. 

The carbon carrier and the 6 biggest sprockets made of titanium save weight and have a high rigidity. A better shifting performance is reached with the updated design of the gear sprockets. 

The Dura Ace cassette is available in 5 different gear combinations.
