SRAM XX1 Eagle AXS Rear Derailleur

SRAM XX1 Eagle AXS is the top-of-range wireless electronic 12-speed mountain bike drivetrain. Its single-ring 10-52T cassette range eliminates the need for a front derailleur, simplifying maintenance while providing 520% gear range. Trek, Yeti, Santa Cruz, Specialized, and Orbea all specify the XX1 AXS on their flagship enduro and trail builds. The wireless AXS shifting system responds in 250 ms — indistinguishable from mechanical shifting in normal use but with the benefit of infinite cable-free adjustment.
