DYNAMIC CHAIN ENGAGEMENT+
SPECIAL GEAR TEETH FUNCTION SHIMANO’s DYNAMIC CHAIN ENGAGEMENT+ is a special gear teeth profile designed for use in single-chainring configurations for XC, enduro, and trail riding. It gives more chain retention and smoother pedaling - even over bumpy terrain. Chain retention of any gear will reduce abrasion and worn out.

HOLLOWTECH II
Providing the best balance of stiffness, strength, weight and rotating performance The concept of HOLLOWTECH II technology is focused on producing a superior crankset which will maximize a rider’s power transfer. The rigidity of the crankset ensures pedaling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more. Naturally, SHIMANO strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO with the company’s own proprietary forging technology that also maintains rigidity. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the right crankarm for more stiffness and a weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedaling stability, allowing for more efficient power transfer. The HOLLOWTECH II crankset has been developed by pursuing the optimum balance of stiffness & rotating performance in a lightweight and beautiful crankset design. High Precision Sealing Moreover, HOLLOWTECH II crankset has a high-precision sealing in the bearing area to increase durability maintaining the excellent rotating performance for long periods.

Instant Release
INSTANT RELEASE shifting replaces the two-stage click and release shifting you are familiar with. INSTANT RELEASE shifting releases cable as soon the lever is activated, resulting in the quickest possible gear changes. Whether it is an upshift with a Top Normal rear derailleur or a downshift with low normal rear derailleur a quicker shift is always a better shift. 
 
2-Way Release
The RAPIDFIRE Plus shifter release lever is commonly called a trigger because it is operated like a pistol, by pulling toward the grip. The release lever of RAPIDFIRE Plus shifters from ALIVIO to XTR can be operated in this same manner but adds the ability to activate a release shift by pushing with the thumb. 
 
Rapidfire Plus
Mountain bikers have used RAPIDFIRE Plus since 1985. RAPIDFIRE Plus is still a winning choice from a wide range of riders from XC racers to freeriders. RAPIDFIRE Plus is suited to quick shifting, giving riders the ability to downshift three gears in one stroke. RAPIDFIRE Plus shifters from DEORE to XTR all feature 2-WAY RELEASE, which means release shifts by pull of the index finger or push of the thumb.

Rapidfire Plus Mono

RAPIDFIRE PLUS MONO LEVER provides intuitive and simple front control that empowers riders to shift both up and down with a single lightweight and compact lever.

Benefits & Features
  • Simple and intuitive single lever operation, quicker access and lighter front shifting enhances concentration.
  • Front double shifting with natural finger positioning supports intuitive shifting operation.
  • Easy front shifting helps riders quickly and accurately respond to rapidly changing conditions.
RAPIDFIRE PLUS MONO LEVER’s simple and intuitive lever operation allows riders to shift both up and down with a single lever. It supports front double shifting with natural finger positioning and intuitive shifting operation while maintaining a solid grip on the handlebar. 2WAY-RELEASE functionality delivers instantaneous push & pull movements to help riders respond quickly and accurately to rapidly changing conditions.

I-Spec-EV
I-SPEC EV creates a clean and action-optimized cockpit that provides greater focus and flexibility for a wider range of riders.

Benefits & Features
  • Wider adjustment range allows riders of various styles, preferences and body styles to adjust to the optimal position.
  • Ergonomic design, quicker lever access, and light operation enhance rider comfort and concentration.
With its wider adjustment range, I-SPEC EV levers can be adjusted to the optimal position to match a wider range of riding styles (ENDURO/XC/etc.), rider preferences and rider anatomies (hand and arm alignment). I-SPEC EV increases brake lever rigidity by moving the brake clamp position inward to create an extra point of contact between the bar and the lever. This additional bracing drastically increases bike control and braking engagement while maintaining space between the clamp and support point for other handlebar accessories.

MICRO SPLINE

MICRO SPLINE delivers lightweight aluminum FREEHUB body to reduce weight and 10 teeth top gear. Use combination with MICRO SPLINE cassette sprocket and FREEHUB.

Benefits & Features
  • Lightweight aluminum MICRO SPLINE FREEHUB seamlessly integrates with small 10-tooth top gears.
  • Smaller and more widely distributed splines limit cog damage on lightweight aluminum FREEHUB.
HYPERGLIDE+
HYPERGLIDE+ drivetrain’s redesigned cassette and chain promotes the next generation of MTB riding by enhancing speed, shifting efficiency and smoothness over any terrain.

Benefits & Features
  • Better chain engagement, stronger retention, and smoother pedaling provide greater power and confidence over rapidly changing terrain.
  • Definitive up & down shifting in both directions boosts riders’ concentration and acceleration.
  • Ultra-efficient drivetrain with smoother power transmission increases comfort and reduces rider stress.
  • A wide range of gearing choices, cassette options and the choice of a single or double front chainring, support a wide variety of MTB riding styles, abilities and preferences.
HYPERGLIDE+ will help kickstart the next generation of mountain bike riding by introducing continuous pedaling over virtually any terrain. This revamped drive system and dedicated chain deliver fast shifting, efficient power transfer and chain stability like you’ve never experienced before. It helps riders adapt to drastically changing trail conditions by precisely judging the optimal shifting moment for consistently smooth operation. HYPERGLIDE+ helps riders seamlessly maneuver rough trails by reducing pedaling shock and cutting shifting times by a 1/3. (vs. current HG system).

INSTANT RELEASE shifting replaces the two-stage click and release shifting you are familiar with. INSTANT RELEASE shifting releases cable as soon the lever is activated, resulting in the quickest possible gear changes. Whether it is an upshift with a Top Normal rear derailleur or a downshift with low normal rear derailleur a quicker shift is always a better shift. 
 
2-Way Release
The RAPIDFIRE Plus shifter release lever is commonly called a trigger because it is operated like a pistol, by pulling toward the grip. The release lever of RAPIDFIRE Plus shifters from ALIVIO to XTR can be operated in this same manner but adds the ability to activate a release shift by pushing with the thumb. 
 
Rapidfire Plus
Mountain bikers have used RAPIDFIRE Plus since 1985. RAPIDFIRE Plus is still a winning choice from a wide range of riders from XC racers to freeriders. RAPIDFIRE Plus is suited to quick shifting, giving riders the ability to downshift three gears in one stroke. RAPIDFIRE Plus shifters from DEORE to XTR all feature 2-WAY RELEASE, which means release shifts by pull of the index finger or push of the thumb.
