Thanks to its “horizontal parallelogram” design, X-Horizon can keep the chain gap the same across all 11 gears. By taking vertical movement out of the equation, this design doesn’t just make shifting faster—it reduces shift force and eliminates ghost shifting. Roller Bearing Clutch technology reduces bounce and chain slap. Cage Lock technology makes wheel removal and installation easier than ever before. Paired with the X01 shifter, the X-Horizon RD forms the backbone of X-Actuation technology: the key to totally smooth shifting action.
