The SRAM NX X-HORIZON™ rear derailleur provides the same smooth, reliable shifting action as XX1-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.
The NX 1×11 X-HORIZON™ rear derailleur is an integral part of the SRAM 1x™ drivetrain system
This rear derailleur was designed specifically for demands of 1x MTB applications
