This new derailleur not only answers the Eagle drivetrain’s need for greater capacity, but it’s also the next evolution of SRAM's proven, 1x-specific design. The larger, 14-tooth X-SYNC lower pulley allows 10- to 50-tooth cassette capacity in this relatively compact design, and also adds to Eagle’s overall smooth-pedaling feel. A new Type-3 roller bearing clutch features a smoother torque curve for a quieter, more consistent operation and feel. The Cage Lock button has been moved back and out of the way, protecting it from trail debris. A redesigned, robust mounting system further improves the Eagle derailleur’s performance and overall durability.
