SHIMANO Deore XT Upgrade Kit M8120 1x12-speed | Cassette 10-45 teeth
With this Shimano Deore XT upgrade kit, you can bring your bike up to the latest technical standard without putting too much strain on your wallet.
The Shimano Deore XT groupset has been a top seller on the bike market for years. It is considered perfect in performance, very reliable and durable. The 12-speed version also continues this tradition.
SHIMANO Deore XT shifters SL-M8100 12-speed right
As one of the contact points, the shifters are an important link between rider and bike. Compared to the M8000 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 tried-and-tested Rapidfire Plus shifting logic with two-way release on the right-hand side has been carried over from the previous version. However, the M8100 shifter with its revised inner workings shifts faster thanks to Instant Release. The shift cable is released immediately when the lever is actuated, allowing the rider to react even more quickly to changing track conditions.
With the I-Spec EV version, the lever can be attached to Deore XT M8100 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.
SHIMANO Deore XT rear derailleur 1x12/2x12 RD-M8120-SGS Shadow+ long cage
The Deore XT M8000 rear derailleur was already known for its clean shifting and smooth chain movement. With the M8100, these characteristics have been further improved and even faster gear changes have been achieved. The rear derailleur was redesigned from the ground up in order to be equipped for the extreme bandwidths of cassettes with 10-45 teeth. The derailleur pulleys are positioned in such a way that they keep the chain at the optimum distance from the cassette in all gears. The size of these 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 Shadow+ system also prevents annoying chain slap on rough surfaces.
For optimum performance, Shimano recommends using this rear derailleur with 1x12 or 2x12-speed drivetrains.
SHIMANO Deore XT cassette 12-speed CS-M8100 10-45 teeth
Smooth and precise shifting has always been a hallmark of Shimano cassettes. In the Hyperglide cassettes of the last generations, the sprockets were positioned in such a way that the chain runs extremely smoothly and with little vibration, especially when shifting to a larger sprocket. With the XT M8100 cassette, Shimano introduces Hyperglide+. Thanks to this technology, shifting now runs just as smoothly even when shifting into a heavier gear and is 1/3 faster than with the CS-M8000 cassette.
This cassette requires Shimano Micro Spline compatible freewheels!
SHIMANO Deore XT chain CN-M8100 12-speed | 126 links with chain lock
The CN-M8100 chain is specially designed for the M8100 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 Deore XT 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 quieter drivetrain. Thanks to a new chromed surface in combination with the proven SIL-TEC coating, the service life of the chain has been kept at the same level as the M8000 chain, despite the smaller outer width.
