Rear Der NX Eagle 12sp

This new 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 Eagles overall smooth-pedalling feel. The Type-3 ROLLER BEARING CLUTCH provides quiet, consistent performance and durability.
