The original mountain bike groupset continues its legacy: the XT M8100 1x12-speed groupset by Shimano

The mountain bike groupset of the first hour continues its legacy of setting the standard for MTB enthusiasts around the world. For nearly three decades now, DEORE XT has stood for proven durability, reliability and performance. The latest version of the drivetrain faced the challenge that modern mountain bikers are riding in increasingly technically demanding terrain – and chasing down trails faster. SHIMANO has done everything to meet this demand and, with the DEORE XT M8100, is bringing cutting-edge technologies for mountain bikes to the starting line for 2019.

Shimano XT FC-M8100-1 12-speed crank 170mm without chainring

The Shimano XT FC-M8100 1x12-speed crank with a 172 mm Q-factor, 52 mm chainline and 142 / 148 mm O.L.D. stands for maximum drivetrain efficiency at a low weight. It offers optimal power transfer and maximum speed for the new XT system, which relies on 1 chainring. In addition to a new dedicated 12-speed chain (CN-M8100) with a correspondingly new 12-speed QUICK LINK connector, SHIMANO also equips the XT M8100 with new cranksets for 12-speed (FC-M8100/8120/8130-1). With a focus primarily on 1x systems, a wide range of chainrings (28T to 36T) is available.        

The new XT 1x12-speed cranks feature DYNAMIC CHAIN ENGAGEMENT+ technology, whose special high-precision tooth profile ensures that the chain finds optimal hold on the upper part of the chainring in rough terrain, while releasing just as smoothly from the bottom of the chainring, thus ensuring the efficiency, smoothness and low noise of the drivetrain. For fast and secure installation of the chainrings, the cranks are equipped with a direct-mount system that allows chainring replacement in a flash. The crank is available in Boost and non-Boost specifications.

Shimano XT SL-M8100 I-Spec EV 12-speed shift lever

The XT SL-M8100-I 12-speed Rapidfire Plus shift lever from Shimano with the new I-Spec EV construction features a lightweight, ergonomic and compact design. Alongside shifting behavior, performance has also been stepped up. With a 20% shorter lever reach for fast shifting and 35% less operating force.

The theory behind the development of the new shift levers was to enable riders to react immediately to sudden changes in the course or racing situation. To this end, the intuitive operation of the handlebar components was significantly optimized once again, which can mean the decisive tenths of a second in a race. A crucial contribution to this is made by the new I-SPEC-EV construction, with which SHIMANO shift levers can be mounted directly on the brake lever, eliminating the need for a clamp and significantly increasing the adjustment range. 14 mm of longitudinal adjustment and 60° of rotational adjustment are available with I-SPEC-EV, allowing every rider to achieve a setup tailored to their individual anatomy or preferences. This special focus that the developers placed on shifting ultimately benefits the rider by allowing them to take their focus away from operation and direct it fully toward the racing action. The RAPIDFIRE Plus MONO lever with its rubber contact surfaces guarantees unprecedented front shifting comfort. With a single press of the lever, the front derailleur shifts to the large chainring; another press releases the latch and the front derailleur shifts back. Simpler, lighter and faster than ever before.

Features

• I-Spec EV - mounting of the shift lever on the brake lever for a clean, streamlined cockpit
• Lever is 20% faster to reach
• Compact, lightweight construction
• Easily accessible lever and low operating force for continuous concentration while riding
• Higher flexibility and action-optimized cockpit layout
• MULTI-Release allows two gear shifts. This allows riders to shift through multiple gears in both directions using the main lever or secondary lever
• INSTANT-Release enables faster shifting. The cable is released immediately upon actuation of the lever
• 2-WAY-Release allows cable release by pushing with the thumb or pulling with the index finger. This means you do not have to adapt your riding style to the rear derailleur; instead, the rear derailleur adapts to your riding style

Shimano XT CS-M8200 12-speed cassette 10-51

The Shimano CS-M8200 with Hyperglide+ for faster shifting is the matching cassette for the new XT 12-speed groupset. The redesigned cassette and chain of the HYPERGLIDE+ drivetrain represent a new generation of MTB touring – with improved speed, shifting efficiency and smoothness on any terrain.

The starting point for this new development in the drivetrain sector was the goal of realizing the smallest possible gear steps, so that the cadence jumps during shifting remain as small as possible, rhythm and propulsion are maintained, and ultimately speed is kept high. This ultimately resulted in the large 51-tooth sprocket, which maintains a uniform difference of 6 teeth per gear especially in the low gears (10-12-14-16-18-21-24-28-33-39-45-51). In addition, the XT is also available with a 10-45T 12-speed cassette (10-12-14-16-18-21-24-28-32-36-40-45), which allows an even finer or tighter gradation between gears on faster or less steep race courses. This makes the 10-45 cassette ideal for XC racers for whom tight gradations are crucial and every gram counts. The 10-51 cassette, on the other hand, is the ideal choice for trail riders, allowing them to tackle even the steepest climbs. For the new 12-speed cassettes, SHIMANO has revised the design of the freehub body for the XT M8100, using the new MICRO SPLINE technology.

Technologies

DYNAMIC CHAIN ENGAGEMENT+
Special tooth profile: SHIMANO's DYNAMIC CHAIN ENGAGEMENT+ is a special tooth profile for single chainrings in XC, enduro and trail applications. It improves chain retention and guidance and makes pedaling easier even in rough terrain. Improved chain guidance in every gear reduces abrasion and wear.

HOLLOWTECH II
Perfect balance between stiffness, stability, weight and rotation efficiency: The concept of HOLLOWTECH II technology was focused on producing an optimized crankset that minimizes the rider's pedaling effort. The high stiffness of the crankset ensures the efficiency of power transfer while pedaling, while its low weight relieves the rider, especially on longer rides. The development of the crankset was carried out with a view to an optimal ratio between stiffness and low weight. HOLLOWTECH technology enables extremely lightweight, hollow crank arms manufactured using SHIMANO's exclusive forging technology to maintain maximum stiffness. In addition, with the HOLLOWTECH II crankset, the right crank is firmly connected to the spindle of the bottom bracket, achieving an optimal balance between maximum stiffness and minimum weight. The outboard bottom bracket offers better weight distribution and more stability, which ensures more efficient power transfer. During the development of the HOLLOWTECH II crankset, emphasis was placed on an optimal ratio between stiffness and rotation efficiency, as well as low weight and attractive appearance. High-quality precision seals: The HOLLOWTECH II crankset also features high-quality precision seals in the bearing area to extend durability and maintain excellent rotation efficiency in the long term.

Instant Release
The Instant Release shifting operation replaces the two-stage click and release process. With Instant Release, the cable is released immediately upon actuation of the lever, achieving the fastest possible gear shift. Regardless of whether you want to shift up with a top-normal rear derailleur or shift down with a low-normal rear derailleur – a faster shift is always a better shift.

2-Way Release
The release lever of a RAPIDFIRE Plus shift lever is pulled toward the grip like a pistol trigger. The release lever of the new RAPIDFIRE Plus shift levers from ALIVIO to XTR can be operated in the same way. However, it also allows shifting optionally by thumb press.

Rapidfire Plus
RAPIDFIRE Plus has been used by mountain bikers since 1985. RAPIDFIRE Plus continues to be successfully used by a wide variety of rider groups, ranging from cross-country racers to freeriders. RAPIDFIRE Plus is suited for quick shifting. Riders can shift down by up to three gear stages with one shift stroke. All RAPIDFIRE Plus shift levers, from DEORE to XTR, are equipped with 2-WAY-RELEASE. This means 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 in a lightweight and compact design. It enables convenient up-shifting and down-shifting.

Advantages and features

• Simple and practical single-lever operation, faster access and easier front shifting promote concentration.
• Double front shifting with a natural finger position makes gear changes easier.
• Riders can conveniently shift before climbs to react quickly and precisely to changing riding conditions

The RAPIDFIRE PLUS MONO enables up-shifting and down-shifting via simple, intuitive single-lever operation. It supports double front shifting with a natural finger position and intuitive shifting movements without losing a firm grip on the handlebar. The 2WAY-RELEASE functionality enables immediate pull and push movements. This makes it easier to react quickly and precisely to rapidly changing conditions.

I-Spec EV
I-SPEC EV creates a clean, action-optimized cockpit layout that helps more riders achieve increased concentration and greater flexibility.

Advantages and features

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

Thanks to the wider adjustment range, I-SPEC EV levers can be positioned optimally for a wide variety of riding styles (ENDURO, XC, etc.), rider preferences and rider anatomy (hand and arm posture). With I-SPEC EV, the brake clamps are moved further inward. This creates an additional contact point between the handlebar and the brake lever, which increases lever rigidity. This extra support significantly improves bike control and braking performance. Space remains between the clamp and the support point for additional handlebar-mounted accessories.

MICRO SPLINE
MICRO SPLINE reduces weight with a lightweight FREEHUB cassette body while featuring a 10-tooth large sprocket. To be used in combination with MICRO SPLINE cassette sprockets and FREEHUB.

Advantages and features

• Lightweight aluminum MICRO SPLINE FREEHUB integrates seamlessly with small 10-tooth top sprockets.
• Smaller, widely spaced splines prevent sprocket damage on the lightweight aluminum FREEHUB.

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

Advantages and features

• Better chain engagement, greater holding force and smoother pedaling provide more performance and a confident ride feel in rapidly changing terrain conditions.
• Clearly defined up-shifting and down-shifting in both directions promotes rider concentration and supports acceleration.
• The highly efficient drivetrain with smoother power transfer ensures more comfort and less stress.
• The large selection of gears and cassettes and combination with one or two chainrings provides support for many different MTB riding styles, experience levels and preferences.

HYPERGLIDE+ is the launchpad for a new generation of MTB experiences because it enables smooth pedaling on virtually any terrain for the first time. The completely revamped drivetrain system with its specially developed chain enables faster shifting, efficient power transfer and unprecedented chain stability. It precisely determines the optimal moment for a gear change to ensure smooth operation. This makes it easier for riders to adapt to abruptly changing terrain conditions. HYPERGLIDE+ helps riders master rough trails with confidence. It dampens pedaling shock and shortens shifting times by one-third (compared to the current HG system).
