The Eagle 90 mechanical system brings the strength and shifting performance of SRAM’s Transmission platform into a cable actuated setup. The Full Mount derailleur eliminates traditional hanger alignment variables and increases durability, while multiple replaceable components make it the most rebuildable derailleur SRAM has produced.
Shifting under load is a hallmark of Eagle Transmission, enabled here by the XS 1275 10–52T cassette and GX T Type Flattop chain. The forged aluminium crankset is specifically configured for Bosch drive units, complete with a seamless Gap Cap interface between crank and chainring for a clean, integrated appearance.
Setup is simplified with a four step process: Prepare. Hang. Tighten. Route. With no limit screws and no B tension adjustment required, installation is straightforward and repeatable. Designed for aggressive trail riding and high torque e-MTB use, Eagle 90 provides reliable, precise mechanical shifting performance without compromise.
