This GX derailleur not only answers the Eagle drivetrain's need for greater capacity, but it's also the next evolution of proven, 1x-specific X-HORIZON design.
The larger, 14-tooth X-SYNC lower pulley allows 10- to 50-tooth cassette, and also adds to Eagle's overall smooth-pedaling feel. The Type-3 ROLLER BEARING CLUTCH features a smoother torque curve for a quieter, more consistent operation and feel.
