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 free-riders. RAPIDFIRE PLUS is suited to quick shifting, giving riders the ability to downshift three gears in one stroke. RAPIDFIRE PLUS shifters from Alivio to XTR all feature 2-Way Release, which means release shifts by a pull of the index finger or push of the thumb.
