The XT shifter SL-M780-B-I by Shimano - I-Spec and Vivid Index

The Shimano XT SL-M780-B-I shifter has been equipped with the clever I-Spec (B) mount, which allows weight- and space-saving integration of shifter and brake lever on the handlebars. In addition, it can be adjusted flexibly in the position and inspires with its " Vivid Index" mechanism with crisp, high-precision shifting operations. You can use it in 2x10-speed as well as in 3x10-speed drivetrains - the switch on the left lever is done with a built-in mode converter.
The SL-M780-B-I is a Rapidfire Plus shifter that can be used to shift down several gears at once. It features the 2-Way Release function: The trigger lever can be operated both by pulling with the index finger and pressing with the thumb. In addition there is the Instant Release technology for immediate release of the cable and - with the 10-speed version - Multi Release for the fastest possible gear change in both directions.

Rapidfire Plus
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.

2-Way Release
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
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 (10-speed only)
In earlier shifting systems, gear changes in one direction took place faster than gear changes in another direction. With Multi Release, two gears can now be changed with one lever actuation. The result: The fastest possible gear change in both directions, regardless of the type of rear derailleur used.

Integration mounting system of shifter and brake lever. It can realise clean appearance, more space for the handle bar area and lightweight.
Note: The XT 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. They can, however, be made compatible with the old I-Spec brakes using a connecting pin (supplied), provided the handlebar grip diameter is less than 32 mm. For handlebar grip diameters from 32 to 36 mm, the old XT I-Spec adapter (now sold out) must be used.

Wat een verademing tegenover standaard deore. I-spec maakt je stuur ook lekker clean.

Отличное сочетание цены и качества. Это действительно так! Прочная конструкция, чёткая работа. Очень удобная функция 2-way, когда скинуть передачу можно как потянув рычажок, так и надавив на него. Сброс цепи на малые звезды: 2 шага.
Подъем цепи на большие звезды: от 1 до 4 шагов за раз.
Excellent combination of price and quality. It really is! Rugged construction, a clear work. A very handy feature 2-way, when the transmission can throw like pulling the lever and pushing it. Reset circuit on a small star: 2 steps.
Lifting chains on large stars: 1 to 4 steps at a time.
