Shimano SL-M390 Acera Rapidfire Plus Shift Lever Set
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.
