Every detail of the 11-speed X1 X-Horizon™ rear derailleur is engineered for smooth, reliable shifting action—from the larger upper pulley offset to the 12-tooth X-Sync™ pulley wheels. By eliminating unwanted chain movement, X-Horizon™ shifts faster, puts an end to ghost shifting and reduces shift force and chain slap. And with Cage Lock™ technology, wheel removal and installation are easier than ever.
