SHIMANO M-9001 XTR 11 SPD 11-40
The CS-M9001 is the suitable cassette for new XTR 11-speed group with 1×11-speed, 2×11-speed and 3×11-speed gearing.
Rhythm is the essence of smooth power transfer and a proper gear step is the key to maintaining rhythm over varied terrain. The CS-M9000 11-speed 11-40T cassette is the widest range cassette Shimano has ever produced and also the most balanced. Thanks to its “rhythm step” progression it maintains calculated, shock-free gear steps from one gear to the next, saving riders energy and helping maintain their flow on the trail.

The real advantage of 11-speed is the ability to have all the range you require without sacrificing the rhythm you need.
