Race Performance!
The XTR groupset is the top end of the SHIMANO MTB portfolio. These components contain everything Shimano has to offer in terms of technology and know-how - it doesn't get any better than this! Optimised for MTB racing, they shine with low weight and best performance. The best racers in the world rely on these parts.
The SHIMANO CS-M9100 cassette reflects exactly that. It is available with two gear ratios designed for 1x12-speed drivetrains. The version with 10-45 teeth (Rythm Step) offers a finer gradation and should therefore be the optimal choice for XC racers in rather flat terrain, while the 10-51 teeth version (Wide Range) provides a huge gear range and makes any ramp, no matter how steep, child's play - hence the recommendation for trail riders.
The combination of titanium, aluminium and steel sprockets is the optimal compromise between light weight and durability.
Equipped with Hyperglide+ sprockets, shifting is extremely precise and smooth, while maintaining a constant frictional connection. It easily copes with shifting under full load. The BEAM SPIDER design saves weight and allows for an additional gear. In addition, the lighter and stiffer pinion design reduces inertia and provides more acceleration. The smaller MICRO SPLINE freewheel allows for the 10T sprocket, makes installation easier and also saves weight.

TECHNOLOGIES
Hyperglide+
A new generation of MTB touring - The completely redesigned drive system with the specially developed chain enables faster shifting, efficient power transmission and unprecedented chain stability. Better chain binding, greater stopping power and smoother pedalling provide more power and a confident ride in rapidly changing terrain conditions. Clearly defined upshifting and downshifting in both directions promotes rider concentration and aids acceleration. The highly efficient drive with smoother power transmission provides more comfort and less stress. HG+ precisely determines the optimal moment to change gear, ensuring smooth pedalling. This makes it easier for riders to adapt to abruptly changing terrain conditions. It also dampens the pedal stroke and shortens shifting times by a third compared to the HG system.
Micro Spline
The smaller aluminium freewheel saves weight and allows a 10-tooth sprocket to be fitted for a wider gear range. The smaller spline reduces the risk of damage from the sprockets on the freewheel.
Shifting without interrupting pedalling, Better acceleration due to lower moment of inertia and weight of the BEAM SPIDER construction, New climbing aids with HYPERGLIDE+ technology ensure the fastest and most comfortable shifting possible.
