Sram NX 11-Speed Rear Derailleur

• X-Sync guide pulley with 12 teeth
• The most affordable 1x rear derailleur with a wide range of features
• The X-Horizon design reduces shifting effort and chain slap
• Long cage

Cage Lock
Thanks to the rear derailleur's CAGE LOCK technology, removing and fitting the rear wheel and chain is easier and faster than ever. Simply push the cage forwards to release chain tension and lock it in place.

Roller Bearing Clutch
ROLLER BEARING CLUTCH rear derailleurs offer maximum riding stability, even on very demanding terrain. ROLLER BEARING CLUTCH technology puts an end to bouncing rear derailleurs and chains coming apart, without sacrificing precision.

X-Actuation
X-ACTUATION technology, developed specifically for SRAM 1x, ensures precise, consistent shifting across the entire cassette.

X-Horizon
The X-HORIZON rear derailleur's parallelogram design limits movement along the horizontal axis, eliminating ghost shifting and reducing shifting effort. For faster, more precise shifting, the large upper pulley offset maintains a constant chain gap in every gear.

X-Sync
The X-SYNC 1x chainrings from SRAM ensure maximum performance and durability. The tall edges of the SRAM X-SYNC teeth engage the chain earlier than traditional triangular teeth. The narrow, sharp tooth profile and rounded, angled edges help guide the chain. To deliver the best possible performance even in muddy terrain, X-SYNC chainrings feature recesses to clear dirt and mud from the chain links and inner rollers. German-made X-SYNC chainrings are an important component of the 1x drivetrain from SRAM.
