Shimano XTR SL.M9000 I-Spec II Shift Lever 11-speed right

Rapidfire Plus
Rapidfire Plus is suitable for fast shifting. The rider can shift up to three gears with one shift stroke.

Instant-Release
The Instant-Release shifting process replaces the two-step click and release process. An elegant appearance and high-quality technologies distinguish Shimano's new SLX. The brand-new mid-range group offers countless of the performance features that already distinguish its "big sister", the Deore XT, and combines them with an excellent price-performance ratio, extreme robustness and comprehensive versatility. Regardless of whether you want to shift up with a top-normal rear derailleur or down with a low-normal rear derailleur - a faster gear change is always a better gear change.

2-Way Release
The trigger lever of a Rapidfire Plus shift lever is usually called a trigger because it is pulled towards the handle like the trigger of a pistol. The release lever of the Rapidfire Plus gear lever can be operated in the same way. However, it can also be used to shift via thumb pressure.

Multi-Release
In previous shifting systems, gear changes were faster in one direction than in the other. Choosing Top-Normal or Low-Normal always meant sacrificing switching speed in one direction in favour of the other. With Multi-Release, two gears can now be shifted with one lever operation. Result: The fastest possible gear change in both directions, regardless of the type of derailleur used.
