The XT SL-M8000-B-I shifter by Shimano - I-Spec and improved ergonomics
The Shimano XT SL-M8000-B-I shifter is designed according to the I-Spec (B) principle, which enables space-saving integration of shifter and brake lever. This also saves weight on the handlebars and improves the look. The shifter is flexibly adjustable in its position and has ergonomic, differently structured levers. It comes with an Optislick cable that reduces the amount of force required for shifting by 20%. The Vivid Index mechanism, which has always been known for its crisp feedback, has been further optimised. The left XT shifter can be used for 2x11 or 3x11 drivetrains without a mode converter.
As a Rapidfire Plus shifter, the SL-M8000-B-I can shift down several gears at once and features 2-Way Release technology, which enables the shift cable to be released both by pulling with the index finger and by pressing with the thumb. Of course there are also Instant Releases for accelerated gear changes and - with the 11-speed version - Multi Releases for the fastest possible shifting in both directions.

The real advantage of 11-speed is the ability to have all the range you require without sacrificing the rhythm you need. Dyna-Sys11 maximizes rhythm while driving and climbing with " rhythm step" gears in the most frequently used range. Driving efficiency is a key drivetrain performance indicator. Dyna-Sys11 means more speed for the same effort.
Rapidfire Plus has been used by mountain bikers since 1985. Rapidfire Plus is still the first choice for a wide range of riding groups, from Cross Country racers to freeriders and downhillers. Rapidfire Plus is suitable for fast shifting. The rider can shift down up to three gears with one shift stroke.
All newer Rapidfire Plus shifters are equipped with 2-way release (release in two directions). This means that the shifter cable is released by pulling with the index finger or pressing with the thumb.
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.
Multi Release (only for 11-speed; pull: one step, push: two steps)
Previous shifting systems shifted faster in one direction than the other. Choosing top normal or low normal always meant sacrificing shifting speed in one direction. Now with Multi Release you can release shift two gears in one stroke. The result - the fastest possible shifting in both directions regardless of rear derailleur choice.
Integration mounting system of shifter and brake lever. It can realise clean appearance, more space for the handle bar area and lightweight.
Note: The I-Spec shifters have a new mount as of 2014 (version B). First of all, there is no compatibility with brake levers with old I-Spec mounts. However, they can be made compatible with the old I-Spec brake levers using a connecting bolt, if the handlebar grip diameter is less than 32 mm. For handlebar grip diameters from 32 to 36 mm, it is not possible to combine the new XT shifter with old I-Spec brake levers.
Optislick cables feature a minimal and uniform electrically coated layer that improves cable routing efficiency and provides excellent corrosion resistance.
