SRAM NX Rear Derailleur 1x11 Speed Long Cage Black

The SRAM NX X-HORIZON™ rear derailleur provides the same smooth, reliable shifting action as XX - 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.
