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.

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.
