Shimano New XTR M9100 12-Speed

New Shimano XTR M9100 Series Mountain Bike Components Debut new 12-speed, Ultra-Efficient Drivetrain and FREEHUB System

The new XTR M9100 group comes in 1×12, 2×12, and 1×11 options and features cassettes including the wide range 10-51T and a smoother shifting 10-45T, direct-mount 1x and 2x cranks, hubs with a new freehub design and internals for improved engagement and disengagement, chains, brakes have a softer and more linear feel with 2-piston and 4-piston versions, rotors with stainless steel and aluminum construction, and shifters with rubber pads and quicker action. The new components will be available in Fall 2018.

Highlights

There are three new Hyperglide+ cassettes that work on their new Micro Spline freehub body: the 12-speed 10-51T Wide Range provides a whopping 510% gear range while the 10-45T Rhythm Step has a 450% range for milder and more ideal steps between gears and the 11-speed 10-45T. The cassettes feature their Beam Spider construction for power transfer with utilizes an aluminum spider and has a combination of aluminum, titanium, and steel cogs.
- 10-51T 12-speed : 10, 12, 14, 16, 18, 21, 24, 28, 33, 39, 45, 51
- 10-45T 12-speed : 10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 40, 45
- 10-45T 11-speed : 10, 12, 14, 16, 18, 21, 24, 28, 33, 39, 45
They have three new derailleurs that feature bigger 13-tooth pulleys and their Shadow RD+ technology: the SGS long cage works with both 10-51 and 10-45 cassettes, the GS medium for 11-speed and 12-speed 10-45 cassettes, and lastly a 2x specific one that works on 10-45 cassettes.
The new HollowTech II cranksets utilize a direct-mount chainring system and come in 1x and 2x options: the 1x comes in a narrow-wide tooth profile in 30t-38t options and two Q-factors (162mm or 168mm), while the 2x is a 38-28T gear combination and also comes in the same two Q-factors versions.
The new Micro Spline freehub body has smaller splines (23 deep rectangular splines), so they could squeeze in the 10-tooth cog and too also prevent damage to the aluminum body and it’s utilized on all the new XTR rear hubs. The hubs (J-Bend and Straight-Pull) feature their new Scylence technology that have a 7.6-degree engagement system that delivers faster pedaling and the two driver plates that disengage entirely for quieter coasting. Unfortunately, the new system will not work on most hubs, and there isn’t a retrofit kit, though supposedly DT Swiss might have an upgradable freehub body in the works?
The new braking system includes both 2-piston XC and 4-piston Enduro versions, along with 140-203mm Freeza stainless steel and aluminum brake constructed rotor options.
Like their current pedal lineup, they’ll have a new standard XC version and a new Enduro platform version.
The new RapidFire Plus shift levers offer 20% quicker lever access time and 35% less shifting operation force compared to their predecessor. For the 2x drivetrain they have a new Rapifire Mono for the front shifter.

PRESS RELEASE

With the introduction of XTR M9100-series, SHIMANO continues the legacy of innovation associated with XTR as the ultimate mountain bike racing component group. New XTR M9100 establishes the new benchmark in mountain bike race performance with unrivaled component customization for every rider and racer’s potential. Engineered for the next generation of race bikes, new XTR components deliver SHIMANO’S widest range gear options with the new 12-speed drivetrain and 10-51T cassette while offering superior shifting and braking systems specifically tuned to meet the demands of all racers.

New SHIMANO technologies further enhance XTR systems, including the revolutionary HYPERGLIDE+ cassette tooth design and new HG chain for improved shifting efficiency up and down the cassette while the MICRO SPLINE FREEHUB delivers a lightweight construction that works seamlessly with the system’s new small 10-tooth cog.

Drivetrain

Optimized and built to the highest demands of racers, new XTR M9100 provides faster and smoother shifting with Shimano’s new HYPERGLIDE+ engineering and MICRO SPLINE Freehub technology. Extensive feedback from Shimano’s global mountain bike athletes delivered insights that one drivetrain does not fit all racers. With that in mind, new XTR M9100 offers a range of gearing choices, single and double front chainring setups and a unique 11-speed drivetrain option that shaves valuable weight off the system without sacrificing performance and speed. Chain retention has been drastically improved as well thanks to advancements with the new M9100 rear derailleur design.

Rider-Tuned Drivetrain Options

1×12 drivetrain with Wide Range 10-51T cassette
1×12 drivetrain with Rhythm Step 10-45T cassette
2×12 drivetrain with a 10-45T cassette for a wide range and ideal gear steps
1×11 lightweight drivetrain with 10-45T cassette

HYPERGLIDE+ Technology

Building on SHIMANO’S long history of shifting technology, new XTR M9100 delivers groundbreaking advancements in drivetrain performance with the introduction of HYPERGLIDE+. The newly redesigned CS-M9100 cassette guides the chain both up and down the cassette, providing faster, smoother shifting in both directions.

Adding to XTR M9100’s smooth drivetrain transmission, the new CN-M9100 HG chain features an extended inner link plate that connects seamlessly with new chainring tooth shapes for Shimano’s most efficient drivetrain. The new design reduces natural vibrations normally caused by the inner and outer chain plates rolling onto the chainring and provides better chain engagement, stronger retention, and smoother pedaling.

Cranks

M9100 HOLLOWTECH II crank construction offers a lighter and stiffer crank design and includes options for both front single and double front chainrings. Two Q-factor options (162mm and 168mm) are available for different rider needs and bike requirements. Chainrings are easily exchanged with the new direct-mount system, and the cranks can be swapped between single and double front chainring setups.

For racers looking for single front chainring insurance, Shimano presents the lightweight and adjustable SM-CD800 chain guide. This unique guide allows for easy height adjustment as well as chain line adjustments by loosening a single bolt and turning a thumb screw. Then, tightening the bolt locks both adjustments at the same time. The chain guide is available in three mounting types: Direct, E, and ISCGO5.

Shifters and Levers

Enhancing lever access and shifting speed, the new RAPIDFIRE PLUS shift levers offer light operation force and more versatility. Shimano’s new I-Spec EV lever design features greater flexibility in mounting for a clean and ergonomic cockpit. And for double chainring systems, the lever simplifies front shifting with a lightweight and compact design that shifts up and down with a single lever.

Braking System

Further improving Shimano’s legendary mountain bike braking system, new XTR increases brake rigidity for greater bike control and optimizes braking performance for different riding styles. The 2-piston XC brake system offers a lightweight package with high rigidity while the Enduro-style 4-piston design prioritizes power and smooth braking feel.

To improve rigidity at the lever, Shimano moved the brake clamp position inboard, creating an extra point of contact between the bar and the lever. This added bracing drastically increases efficiency and control over the bike while offering quick brake engagement. The new design minimizes the impact on cockpit real estate, creating space between the clamp and support point for mounting other handlebar accessories.
