The XT cassette has been computer designed to incorporate specifically positioned shift ramps and tooth profiles for smoother and more efficient shifting.
The result is a transmission system which shifts into gear every time you use the dual control levers.
The 9-speed cassette is constructed from an aluminium carrier and steel sprockets and weighs in at 264g.

2 sprocket combinations are available as follows:
11-12-14-16-18-21-24-28-32T
