Core Technologies

  1. SIS Rear Index Shifting System
    This system integrates indexed shift lever structure, low-friction rear indexed shift cable and smooth-action rear derailleur, belonging to the official Shimano Index Shifting System.
  2. HG (HyperGlide)
    HyperGlide freewheels feature specially designed tooth profiles and shift ramps to stabilize chain movement during gear shifting, realizing fast and accurate indexed gear changes.
  3. Double Servo Mechanism
    Shimano double servo swing arm structure ensures the rear derailleur moves along the optimal path, keeping the guide pulley at a fixed distance from each sprocket tooth for smoother and more reliable shifting performance.
