The new SRAM NX Eagle Rear Derailleur brings SRAM's Eagle technology down to an incredible new price point. Affordable, dependable and highly durable, the NX Eagle Rear Derailleur is designed to be tough and reliable, all while providing seamlessly smooth shifting performance. The NX Eagle Rear Derailleur features SRAM's X-Actuation technology which has been developed specifically for SRAM 1x drivetrains to ensure that shifting remains sharp, smooth and consistent across the entire cassette. The NX Eagle Derailleur comes equipped with a larger 14-tooth X-Sync 2 lower pulley to allow for an 11-50t or 10-50t cassette, and contributes to the Eagle s smoother pedaling feel. With a focus on long wear-life, X-Sync 2 reduces friction and the accumulation of mud, grit and grime to prolong the life of your chainring, chain and your cassette. The Type-3 Roller Bearing Clutch features a smoother torque curve for a quieter and more consistent operation and feel, and the Cage Lock feature which makes wheel installation faster and easier has been re-positioned to keep it protected and out of the way. If you want access to the massive range of SRAM s Eagle drivetrains, the NX Eagle Rear Derailleur offers great performance and incredible value for money.
