SHIMANO XTR Upgrade Kit M9100 1x12 | Micro Spline | Cassette 10-51 teeth
XTR upgrade kit for Micro Spline compatible hubs and wheels
The XTR M9100 components are ideal for race-oriented drivers who are looking for the best drive and shift performance with low weight.
Rear derailleur RD-M9100 Shadow + SGS (long cage)
The XTR M9000 rear derailleur was already known for its clean gear changes and smooth chain running. With the M9100, these properties could be further improved and even faster switching operations realized. In order to be equipped for the extreme bandwidths of the cassettes with 10-51 teeth, the rear derailleur was designed from scratch. The shift pulleys were positioned in such a way that they keep the chain at an optimal distance from the cassette in all gears. The size of the pulleys has also grown to 13 teeth. This not only offers the chain better guidance, but also ensures a smoother and more energy-saving run. The quiet chain run is supported by the Shadow + design with vibration damper.
Shift lever SL-M9100
As one of the contact points, the shift levers are an important link between the rider and the bike. Compared to the M9000 Shifter, the operating forces were reduced by 35% due to a changed gear ratio in combination with a lower cage voltage on the rear derailleur. The tried-and-tested Rapidfire Plus switching logic with levers that can be switched on both sides (2-way release) was adopted from the previous version. However, the M9100 Shifter shifts 20% faster thanks to a revised interior, which enables the pilot to react even faster to changing route conditions.
With the I-Spec EV version, the lever can be attached to XTR M9100 / 9120 brake levers to save space. In addition, the assembly via the new standard offers a 14 mm wide, lateral adjustment range and the shifter can also be rotated by 60 degrees. The shifter can be adjusted for use with an 11-speed or 12-speed cassette using a set screw on the underside.
Cassette CS-M9100 12-speed (10-51 teeth)
Shimano follows suit and also relies on a 12-speed drive for the XTR M9100 group.
The cassette with a maximum bandwidth (10-51 teeth) is particularly suitable for touring and all-mountain use, since the optimally graded grading conserves power reserves, especially on long climbs.
Furthermore, it impresses with its excellent switching performance and high wear resistance. An intelligent material mix of aluminum, steel and titanium increases the service life, but at the same time reduces the weight of the cassette.
Chain CN-M9100 12-speed (126 links)
The CN-M9100 chain is specially designed for the M9100 chainrings and cassettes. The chain mates perfectly with the Dynamic Chain Engagement + (DCE +) narrow-wide tooth profiles of the new XTR chainrings thanks to the milled grooves on the inside of the link plates. The design leads to a closer fit of the chain on the teeth. Vibrations are avoided and the quieter chain run is not only felt when pedaling, but is also expressed acoustically by a 4db quieter drive. Thanks to a new chromed surface in combination with the tried-and-tested SIL-TEC coating, the service life of the chain could be kept at the level of the M9000 chain, despite the smaller external width.
