Shimano XTR CS-M9100-12 12-Speed Cassette

The XTR 12-speed cassette CS-M9100-12 by Shimano - Wide Range or Rhythm Step?

The Shimano XTR 12-speed cassette CS-M9100-12 is available in two versions: 10-45 T for cross-country racers, where every gram counts and even gradation is desired, and 10-51 T for trail and enduro riders, for whom a wide range is important and who also want to excel on the steepest ramps. Shimano calls the first version " Rhythm Step" , the second is called " Wide Range" . All CS-M9100 cassettes are made of three different materials - steel, titanium and aluminium. They are only compatible with the innovative Shimano Micro Spline freehub system. Groundbreaking Hyperglide+ technology ensures that you can even continue pedalling while shifting.

Technology:

Hyperglide+ / HG+
Hyperglide+ is the efficient further development of the Hyperglide system by Shimano. These are shifting aids and specially shaped sprocket teeth that make shifting to larger or smaller sprockets suppler, smoother and quieter. The system of small rivets attached to the side of the sprocket and milled or pressed-in ramps ensures that the chain is already carried along by the next sprocket during the shifting process before it leaves the previous sprocket. Hyperglide+ is optimised for faster shifting and shifting under load and has a more efficient chain connection, holding power and power transfer when combined with a compatible HG chain. Compared to Hyperglide, the shifting time is reduced by one third and the pedal stroke is noticeably reduced. HG+ enables a completely new chain stability and thus offers a safe riding experience.

Micro Spline
Micro Spline is an innovative tooth profile on MTB freehub bodies from Shimano. All Shimano 12-speed MTB cassettes with a 10-tooth sprocket are equipped with Micro Spline freehub toothing. The significantly higher and finer toothing enables a stiffer connection between the cassette and the hub body. The resulting increased contact area ensures reliable power transmission, minimises wear and prevents deformation of the freehub and sprocket.
