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

The pioneering mountain bike groupset continues its legacy of setting the standard for MTB enthusiasts worldwide. For almost three decades now, the DEORE XT has been characterised by proven durability, reliability and performance. The latest version of the groupset faced the challenge that modern mountain bikers are riding on increasingly technically demanding terrain – and are also racing down the trails faster than ever. SHIMANO has done everything possible to meet this demand and, with the DEORE XT M8100, is once again bringing cutting-edge mountain bike technology to the market in 2019.

Shimano XT FC-M8100-1 12-speed crankset 180 mm without chainring

The Shimano XT FC-M8100 1x12-speed crankset, with a 172 mm Q-factor, 52 mm chainline and 142 / 148 mm mounting width, delivers maximum drivetrain efficiency whilst keeping weight to a minimum. It offers optimum power transfer and maximum speed for the new XT system, which relies on a single chainring. In addition to a new, specialised 12-speed chain (CN-M8100) with a corresponding new 12-speed QUICK LINK fastener, SHIMANO has also equipped the XT M8100 with new cranksets for 12-speed systems (FC-M8100/8120/8130-1). For those who predominantly use single-chainring systems, a wide range of chainrings (28T to 36T) is available.

The new XT 1x12-speed cranksets feature DYNAMIC CHAIN ENGAGEMENT+ technology, whose specially engineered, high-precision tooth profile ensures that the chain maintains optimal grip on the upper part of the chainring on rough terrain, whilst simultaneously disengaging just as effectively from the chainring at the bottom, thereby ensuring the drivetrain’s efficiency, smooth operation and quiet running. For quick and secure fitting of the chainrings, the cranksets are equipped with a Direct-Mount system, which allows chainrings to be changed in the blink of an eye. The crankset 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 shifter from Shimano, featuring the new I-Spec EV design, stands out thanks to its lightweight, ergonomic and compact design. As well as improved shifting action, performance has also been stepped up a gear. With a 20 per cent shorter lever reach for fast shifting and 35 per cent less effort required.

The theory behind the development of the new shift levers was to enable the rider to react immediately to sudden changes in the course or the race situation. To this end, the intuitive operation of the handlebar controls has been significantly optimised once again, which can mean a decisive advantage of tenths of a second in race situations. A key factor in this is the new I-SPEC-EV design, which allows SHIMANO shift levers to be mounted directly onto the brake lever, thereby eliminating the need for a clamp and significantly increasing the adjustment range. With I-SPEC-EV, 14 mm of adjustment is available in the longitudinal direction and 60° in the rotational direction, allowing every rider to set up their bike to suit their individual anatomy or preferences. This particular focus that the developers have placed on shifting ultimately benefits the rider by allowing them to shift their focus away from operating the controls and fully onto the race. The RAPIDFIRE Plus MONO lever, with its rubber contact surfaces, guarantees unprecedented shifting comfort at the front. A single press of the lever shifts the derailleur to the large chainring; another press releases the lock and the derailleur shifts back. Simpler, easier and faster than ever before.

Features

• I-Spec EV – Mounting the shifter to the brake lever for a clean, tidy cockpit
• The lever is 20% quicker to reach
• Compact, lightweight design
• Quickly accessible lever and minimal effort required for operation, allowing for sustained concentration whilst riding
• Greater flexibility and an action-optimised cockpit layout
• MULTI-Release allows for two-step gear changes. This means you can shift through several gears in both directions using either the main lever or the secondary lever
• INSTANT-Release enables faster gear changes. The cable is released immediately when the lever is actuated
• 2-WAY-Release allows the cable to be released by pushing with your thumb or pulling with your index finger. This means you don’t 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 perfect cassette for the new XT 12-speed groupset. The redesigned cassette and chain of the HYPERGLIDE+ drivetrain represent the next generation of MTB touring – offering improved speed, shifting efficiency and smooth operation on any terrain.

The starting point for this new development in the drivetrain was the aim of achieving the smallest possible shift increments, so that changes in cadence during shifting remain as minimal as possible, rhythm and propulsion are maintained, and speed is ultimately kept high. This ultimately resulted in the large 51-tooth sprocket, which maintains a consistent difference of 6 teeth per gear, particularly in the lower gears (10-12-14-16-18-21-24-28-33-39-45-51). In addition, however, the XT also comes with a 10-45T 12-speed cassette (10-12-14-16-18-21-24-28-32-36-40-45), which allows for even finer or closer spacing between the gears on faster or less steep race courses. This makes the 10–45 cassette ideal for XC racers, for whom close gear spacing is crucial and every gram counts. The 10–51 cassette, on the other hand, is the ideal choice for trail riders, enabling them to tackle even the steepest climbs. For the new 12-speed cassettes, SHIMANO has redesigned the freehub body on the XT M8100, utilising the new MICRO SPLINE technology.

Features

Technologies

DYNAMIC CHAIN ENGAGEMENT+
Special tooth profile SHIMANO’s DYNAMIC CHAIN ENGAGEMENT+ is a special tooth profile designed for single chainrings used in XC, Enduro and Trail riding. It improves chain retention and guidance, making pedalling easier even on rough terrain. Improved chain guidance in every gear reduces abrasion and wear.

HOLLOWTECH II
The perfect balance between stiffness, stability, weight and rotational efficiency. The HOLLOWTECH II technology was designed to produce an optimised crankset that minimises the effort required by the rider to drive the bike. The high stiffness of the crankset ensures efficient power transfer whilst pedalling, whilst its low weight reduces the rider’s effort, particularly over longer distances. The crankset was developed with a view to achieving an optimal balance between stiffness and low weight. HOLLOWTECH technology enables extremely lightweight, hollow crank arms, which are manufactured using SHIMANO’s exclusive forging technology to achieve maximum stiffness. Furthermore, in the HOLLOWTECH II crankset, the right-hand crank is firmly connected to the bottom bracket spindle, achieving an optimal balance between maximum stiffness and minimum weight. The external bottom bracket offers better weight distribution and greater stability, ensuring more efficient power transfer. During the development of the HOLLOWTECH II crankset, emphasis was placed on achieving an optimal balance between stiffness and rotational efficiency, as well as low weight and an attractive appearance. High-quality precision seals The HOLLOWTECH II crankset also features high-quality precision seals in the bearing area to extend its service life and maintain its excellent rotational efficiency over the long term.

Instant Release
The Instant Release shifting mechanism replaces the two-stage click-and-release process. With Instant Release, the cable is released immediately upon actuating the lever, thereby achieving the fastest possible gear change. Whether you’re shifting up with a Top-Normal derailleur or down with a Low-Normal derailleur – a faster shift is always a better shift.

2-Way Release
The release lever on a RAPIDFIRE Plus shifter is pulled towards the grip, much like the trigger of a pistol. The release lever on the new RAPIDFIRE Plus shifters, from ALIVIO to XTR, can be operated in the same way. However, it can also be used to shift gears simply by pressing with 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 riders, ranging from cross-country competitors to freeriders. RAPIDFIRE Plus is ideal for fast gear changes. The rider can shift down by up to three gears with a single lever movement. All RAPIDFIRE Plus shift levers, from DEORE to XTR, are fitted 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 derailleur lever with a lightweight and compact design. It allows for comfortable upshifting and downshifting.

Advantages and features

• The simple and practical single-lever operation, quicker access and easier front shifting help you stay focused.
• Dual front shifting with a natural finger position makes changing gears easier.
• Riders can shift comfortably from the front to react quickly and precisely to changing riding conditions

The RAPIDFIRE PLUS MONO enables upshifting and downshifting via a simple and intuitive single-lever operation. It supports dual front shifting with a natural finger position and intuitive shifting movements, without having to release your firm grip on the handlebars. 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, performance-optimised cockpit layout that helps more riders achieve greater concentration and flexibility.

Benefits and features

• Thanks to the wider adjustment range, a wide variety of riders can find their ideal position – regardless of riding style, preferences and physique.
• The ergonomic design, quicker lever access and smooth operation enhance riding comfort and promote concentration.

Thanks to the wider adjustment range, the I-SPEC EV levers can be set to the optimal 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 calipers are positioned further inwards. This creates an additional contact point between the handlebars and the brake lever, which increases the lever’s stiffness. This additional support significantly improves control over the bike and braking performance. At the same time, there is still space between the clamp and the support point for other handlebar-mounted accessories.

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 a MICRO SPLINE cassette sprocket and FREEHUB.

Advantages and features

• The lightweight aluminium MICRO SPLINE FREEHUB integrates seamlessly with small 10-tooth upper sprockets.
• Smaller and more widely spaced teeth prevent damage to the sprockets on the FREEHUB, which is made from lightweight aluminium.

HYPERGLIDE+
The redesigned cassette and chain of the HYPERGLIDE+ drivetrain represent the next generation of MTB touring – offering improved speed, shifting efficiency and smooth operation on any terrain.

Benefits and features

• Improved chain retention, greater holding force and smoother pedalling deliver greater power and a confident riding experience in rapidly changing terrain conditions.
• The clearly defined upshifts and downshifts in both directions help the rider stay focused and support acceleration.
• The highly efficient drivetrain with smoother power transfer ensures greater comfort and less stress.
• The wide range of gear systems and cassettes, combined with single or double chainrings, caters to a wide variety of MTB riding styles, experience levels and preferences.

HYPERGLIDE+ is the gateway to the next-generation MTB experience, as it enables smooth pedalling on virtually any terrain for the first time.The drivetrain, redesigned from the ground up with a specially developed chain, enables faster gear changes, efficient power transfer and unprecedented chain stability. It precisely determines the optimal moment for shifting, ensuring 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 pedal kickback and reduces shift times by a third (compared to the current HG system).
