Hollowtech II The development of the Hollowtech II crankset took place with a view to optimal and efficient power transmission. Hollowtech technology enables extremely light, hollow crank arms manufactured using Shimano's exclusive forging technology for maximum rigidity. The result are mountain bike components that provide the right setup for almost every biker.The SL-M7000 shift levers are equipped with the proven Rapidfire Plus technology and 2-Way-Release. They contribute to the high-precision but ultra-light gearshifting with the new SLX and ensure consistent shifting performance with minimum operating forces.
2-Way-Release Rapidfire Plus levers are equipped with 2-Way Release (release in two directions). This means that the cable is released by pulling with the index finger or pressing with the thumb.
