Introducing the latest NX Eagle™ derailleur showcasing the proven SRAM 1x-specific X-HORIZON™ design. The enhanced 14-tooth X-SYNC™ lower pulley seamlessly accommodates both 11- to 50-tooth and 10- to 50-tooth cassette capacities, contributing to the NX Eagle's smooth pedalling sensation. The Type-3 ROLLER BEARING CLUTCH™ ensures consistent, quiet performance and long-lasting durability.

Cage Lock Technology

The inclusion of CAGE LOCK™ technology within the rear derailleur streamlines wheel removal, installation, and chain setup. A simple push of the cage forward generates slack and secures it in position, facilitating quicker and more convenient maintenance.

X-HORIZON™ Technology

By employing X-HORIZON™ technology in the rear derailleur, a 'straight parallelogram' design restricts movement to the horizontal axis, effectively eliminating ghost shifting while decreasing the force required for shifts. The ingenious large upper pulley offset configuration guarantees a uniform chain gap across all gears, ensuring swifter and more precise shifts.
