GX 1x11 X-HORIZON rear derailleur

The SRAM GX X-HORIZON™ rear derailleur is designed for smooth, reliable shifting, thanks to a wider upper pulley offset and 12-tooth X-SYNC™ pulleys. By eliminating unwanted chain movement, X-HORIZON™ shifts faster, eliminating ghost shifts and reducing shift force and chain slap. And thanks to CAGE LOCK™ technology, wheel removal and installation are easier than ever.
