The Shimano Altus SL-M2010 Rapidfire shift lever is suitable for fast shifting. The rider can downshift by up to three gears with one shift stroke - perfect for mountain bike riders who want reliable shifting performance. Rapidfire Plus has been used by mountain bikers since 1985 and is still the first choice of various rider groups, from XC racers to freeriders and downhillers. Rapidfire Plus enables fast shifting, whereby the rider can downshift by up to three gear steps with one shift stroke. All Rapidfire Plus shift levers, from Shimano Deore to XTR, are equipped with 2-way release, which means that the shift cable is released by pulling with the index finger or pressing with the thumb. The Optical Gear Display shows the rider which gear is engaged. The rider can see how many gears he still has available upwards and downwards and can therefore shift gears more consciously. Optislick cables are provided with a minimal, uniform galvanic coating, which enables more efficient cable routing and is characterised by excellent corrosion resistance.
