The NX Eagle derailleur features the proven SRAM 1x-specific X-HORIZON design.

The larger, 14-tooth X-SYNC lower pulley easily facilitates 11- to 50- and 10- to 50-tooth cassette capacity, and also adds to NX Eagle’s overall smooth-pedaling feel.

The Type-3 ROLLER BEARING CLUTCH provides quiet, consistent performance and durability.

• Completely new rear derailleur incorporating our proven X-HORIZON design and new Type-3 ROLLER BEARING CLUTCH technology.
• Eagle ecosystem-engineered mounting system and CAGE LOCK positioning add robustness.
• Eagle pulley technology provides greater efficiency, crisper shifting and quieter operation.
• Max. cassette sprocket size 50T.
• Weight: 340 g

With Cage Lock technology in the rear derailleur, wheel removal and installation – as well as chain installation – becomes faster and simpler. Just push the cage forward to create slack, and lock it into place.

Roller Bearing Clutch technology eliminates derailleur bounce and chain slap without sacrificing precision.

X-Actuationwas developed specifically for SRAM 1x drivetrains, X-Actuation keeps shifting sharp and consistent across the entire cassette.

X-Horizon. This derailleur’s “straight parallelogram” design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force.

For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.
