SHIMANO XTR Upgrade Kit M9100 1x12 | Micro Spline | Cassette 10-45 teeth
XTR upgrade kit for Micro Spline compatible hubs and wheels
The XTR M9100 components are ideal for race-oriented riders who are looking for the best drivetrain and shifting performance with low weight.
Rear derailleur RD-M9100 Shadow+ GS (medium-length cage )
The XTR M9000 rear derailleur was already known for its clean shifting and smooth chain operation. With the M9100, these characteristics have been further improved and even faster gear changes have been achieved. In order to be equipped for the extreme bandwidths of cassettes with 10-45 teeth, the rear derailleur was redesigned from the ground up. The derailleur pulleys have been positioned in such a way that they keep the chain at the optimum distance from the cassette in all gears. The size of the derailleur pulleys has also been increased to 13 teeth. This not only provides the chain with better guidance, but also ensures smoother and more energy-efficient running. The smooth chain run is supported by the Shadow+ design with vibration damper.
SL-M9100 shifters
As one of the contact points, the shift levers are an important link between rider and bike. Compared to the M9000 shifter, the operating forces have been reduced by 35% thanks to a modified gear ratio in combination with a lower cage tension on the rear derailleur. The proven Rapidfire Plus shifting logic with two-way release levers has been carried over from the previous version. However, the M9100 shifter shifts 20% faster thanks to a revised inner workings, allowing the rider to react even faster to changing track conditions.
With the I-Spec EV version, the lever can be attached to XTR M9100/9120 brake levers to save space. In addition, the new standard mounting offers a 14 millimeter 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 via an adjusting screw on the underside.
CS-M9100 12-speed cassette (10-45 teeth)
Shimano follows suit and also uses a 12-speed drivetrain for the XTR M9100 groupset.
The narrowly stepped cassette (10-45 teeth) with lower cadence jumps when shifting is particularly suitable for XC and marathon racers who can conserve their power reserves by pedaling in the optimum frequency range.
It also impresses with its outstanding shifting performance and high wear resistance. An intelligent material mix of aluminum, steel and titanium increases the service life while at the same time reducing the weight of the cassette.
CN-M9100 12-speed chain
The CN-M9100 chain is specially matched to the M9100 chainrings and cassettes. Thanks to cut-outs on the inside of the plates, the chain harmonizes perfectly with the Dynamic Chain Engagement+ (DCE+) Narrow-Wide tooth profiles of the new XTR chainrings. The design results in a tighter fit of the chain on the teeth. Vibrations are avoided and the smoother chain run is not only noticeable when pedaling, but also manifests itself acoustically through a 4db quieter drive. Thanks to a new chrome-plated surface in combination with the proven SIL-TEC coating, the service life of the chain has been kept at the same level as the M9000 chain, despite the smaller outer width.
