The original mountain bike groupset continues its legacy: XT M8100 from Shimano

The original mountain bike groupset continues its legacy of setting the standard for the world's MTB enthusiasts. For almost three decades now, the DEORE XT has been characterised by proven durability, reliability and performance. The latest version of the groupset was confronted with the challenge that the modern mountain biker is travelling in ever more technically demanding terrain - and is also chasing faster over the trails. SHIMANO has done everything it can to meet this challenge and is once again launching cutting-edge technology for mountain bikes in 2019 with the DEORE XT M8100.

Scope of delivery - Shimano XT M8100 1x12-speed upgrade kit 10-51 clamp

• XT SL-M8100 12-speed shifter with clamp right incl. inner cable 2050mm & outer housing 1800mm
• XT RD-M8100 12-speed rear derailleur SGS
• XT CS-M8200 12-speed cassette 10-51 incl. retaining ring

The XT SL-M8100 12-speed Rapidfire Plus shift lever from Shimano with clamp construction is characterised by its lightweight, ergonomic and compact design. In addition to the shifting behaviour, the performance also increases by one gear. With 20 % shorter lever reach for fast shifting and 35 % less effort.

The Shimano XT RD-M8100 12-speed rear derailleur for 10-45 cassette is characterised by an elegant yet aggressively angled design and an attractive anodised aluminium surface. New, large guide and tension pulleys with 13 instead of the previous 11 teeth ensure improved shifting performance. These also contribute to improved chain stabilisation, as does the Shadow RD+ design with friction damper.
The Shimano CS-M8100 with Hyperglide+ for faster shifting is the right cassette for the new XT 12-speed groupset. The redesigned cassette and chain of the HYPERGLIDE+ drivetrain represent the new generation of MTB touring - with improved speed, shifting efficiency and smoothness on any terrain.
For the new 12-speed cassettes, SHIMANO has revised the design of the freehub on the XT M8100 and uses the new MICRO SPLINE technology.

The special design of the new Shimano XT CN-M8100 12-speed chain ensures improved shifting behaviour and smoother running - even on rough terrain. The SM-CN910-12 quick-link fastener, which is also new, enables easy installation.

The XT CN-M8100 HYPERGLIDE+ chain has been optimised from the ground up and is an integral part of the new drivetrain. With its high-precision moulded contact surfaces to the chainring and cassette teeth, it ensures fast, precise and smooth shifting in both directions even under the highest loads. Chrome-plated inner plates further increase durability.

Technologies

Instant Release
The Instant Release shifting process replaces the two-stage click and release process. With Instant Release, the cable is released immediately when the lever is actuated, thus achieving the fastest possible gear change. Regardless of whether an upward gear change is to be made with a top-normal rear derailleur or a downward gear change with a low-normal rear derailleur - a faster gear change is always a better gear change.

2-Way Release
The release lever of a RAPIDFIRE Plus shifter is pulled towards the grip like the trigger of a pistol. The release lever of the new RAPIDFIRE Plus shift levers from ALIVIO to XTR can be operated in the same way. However, it can also be used to shift gears by pressing the thumb.

Rapidfire Plus
RAPIDFIRE Plus has been used by mountain bikers since 1985. RAPIDFIRE Plus continues to be used successfully by a wide variety of rider groups, from cross-country competition riders to freeriders. RAPIDFIRE Plus is suitable for fast shifting. The rider can downshift by up to three gears with a single shift. All RAPIDFIRE Plus shift levers, from DEORE to XTR, are equipped with 2-WAY-RELEASE (release in two directions). This means that the shift cable is released by pulling with the index finger or pressing with the thumb.

Rapidfire Plus Mono
The RAPIDFIRE PLUS MONO lever is a user-friendly and simple front shifting element with a lightweight and compact design. It enables convenient upshifting and downshifting.

Advantages and features

• The simple and practical single-lever operation, faster access and easier front shifting promote concentration.
• Double front shifting with natural finger position facilitates gear changes.
• Riders can shift comfortably in front to react quickly and precisely to changing riding conditions

The RAPIDFIRE PLUS MONO enables upshifting and downshifting via simple and intuitive single-lever operation. It supports double front shifting with natural finger position and intuitive shifting movements without releasing the fixed grip on the handlebars. The 2WAY-RELEASE functionality enables immediate pulling and pushing movements. This makes it easier to react quickly and precisely to rapidly changing conditions.

I-Spec-EV
I-SPEC EV creates a clean, action-optimised cockpit layout that helps more riders to increase concentration and flexibility.

Advantages and features

• Thanks to the wider adjustment range, a wide variety of riders can find their optimum position - regardless of riding style, preferences and body type.
• The ergonomic design, faster lever access and smooth operation increase riding comfort and promote concentration.

Thanks to the larger adjustment range, the I-SPEC EV levers can be set to the optimum position for a wide variety of riding styles (ENDURO, XC, etc.), rider preferences and rider anatomy (hand and arm position). With I-SPEC EV, the brake clamps are positioned further inwards. This creates an additional contact point between the handlebars and the brake lever, which increases the stiffness of the lever. This additional support significantly improves control of the bike and the braking effect. There is still space between the clamp and the support point for other accessories mounted on the handlebars.

MICRO SPLINE
MICRO SPLINE MICRO SPLINE reduces weight with a lightweight FREEHUB cassette hub, whereby the largest chainring has 10 teeth. Use in combination with MICRO SPLINE cassette sprocket and FREEHUB.

Advantages and features

• Lightweight aluminium MICRO SPLINE FREEHUB integrates seamlessly with small upper 10-tooth sprockets.
• Smaller and wider teeth prevent pinion damage on the lightweight aluminium FREEHUB.

HYPERGLIDE+
The redesigned cassette and chain of the HYPERGLIDE+ drivetrain represent the new generation of MTB touring - with improved speed, shifting efficiency and smoothness on any terrain.

Advantages and features

• Better chain retention, greater holding power and smoother pedalling provide more power and a safer riding experience in rapidly changing terrain conditions.
• The clearly defined upshifting and downshifting in both directions promotes the rider's concentration and supports acceleration.
• The highly efficient drive with more even power transmission ensures greater comfort and less stress.
• The wide range of gears and cassettes and the combination with one or two chainrings offers support for many different MTB riding styles, experience levels and preferences.

HYPERGLIDE+ is the launch pad for the new generation MTB experience, as it enables smooth pedalling on practically any terrain for the first time, while the completely redesigned drive system with its specially developed chain enables faster shifting, efficient power transmission and unprecedented chain stability. It precisely determines the optimum moment for the gear change and thus ensures smooth operation. This makes it easier for riders to adapt to abruptly changing terrain conditions. HYPERGLIDE+ helps riders to master rough trails with confidence. It dampens the pedal stroke and reduces shifting times by a third (compared to the current HG system).
