The X01 Eagle 12-Speed rear derailleur sits second in their range and draws loads of features from the top tier XX1 range. This is the next evolution of SRAM’s proven 1x drivetrains, featuring their proven 1x specific X-HORIZON™ design to provide the same precise, reliable performance you expect from Eagle in a lightweight and reliable package. The larger, 14-tooth X-SYNC™ lower pulley easily facilitates 10- to 50-tooth cassette capacity, and also adds to X01 Eagle's overall smooth-pedalling feel and platform. The new and updated Type-3 ROLLER BEARING CLUTCH™ features a smoother torque curve to provide quiet, consistent performance and durability no matter the terrain.
