Technologies
Multi Release – revious 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.
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 2WAY-RELEASE, which means release shifts by pull of the index finger or push of the thumb.
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 SHIMANO ALIVIO to XTR can be operated in this same manner but adds the ability to activate a release shift by pushing with the thumb
I-SPEC EV –  creates a clean and action-optimized cockpit that provides greater focus and flexibility for a wider range of riders.

Instant Release – shifting replaces the two-stage click and release shifting you are familiar with.
