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&trade rear derailleur forms the backbone of X-ACTUATION™ technology: the key to totally smooth shifting action.
