This derailleur is part of the SRAM S100 Eagle Drivetrain range, which replaces the SX and NX Eagle 12 speed range. The S100 range is backward compatible with SX and NX Eagle.

Designed for high-torque applications and consistent shifting performance, the Eagle S100 continues the Eagle promise of accurate, dependable gear changes across varied terrain.
