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. - Speed (RD): 11s - Cable pull Ratio: X-actuation - Cage (RD): Long - Max tooth: 42 - Color (RD): Black - Pulley bearings material: Steel - Cage material (RD): Aluminum - Weight (g): 256
