Shimano XTR CS-M9101 12sp Cassette

The Shimano XTR CS-M9101 cassette is characterised by itsBeam Spiderconstruction which enables enormous weight savings and at the same time promises long durability. Not only the spider but also the three largest sprockets are made of aluminium. The highlight, however, are the 5 medium sprockets made of titanium. The incredibly light cassette also features theHyperglide+technology which guarantees high shifting speed, precision and smoothness when shifting up and down and contributes to an extremely quiet drivetrain.

The 12-speed cassette is available in 2 versions: 10-45 and 10-51 teeth. The 10-45 teeth cassette produces as few gear jumps as possible while the 10-51 teeth cassette covers a wide gear range.

Hyperglide+

The conventional Hyperglide technology ensures smooth shifting upwards thanks to small shifting ramps, which guide the chain towards the next larger sprocket. Also Hyperglide+ uses this functionality but applies it in the opposite direction, too, preventing the chain from falling down when shifting downwards. The result is a smooth and consistent shifting in both directions, free of vibrations and without disrupting the cadence.

Micro Spline

The aluminium freewheel with 22 evenly spaced teeth keeps the cassette firmly under control for immediate response and also allows the use of a 10 teeth sprocket. In addition, the smaller and compared to the usual Hyperglide freewheel bodies more extensive gearing prevents rotor damage.
