Eagle 90 Transmission delivers mechanical shifting precision with unmatched durability
What Our Gearhead® Experts Are Saying:
"The Eagle 90 setup completely changes what I thought mechanical shifting could be. The Full Mount derailleur is super solid, setup is refreshingly simple, and the feel under load is crisp—even better than some electronics I’ve ridden. Plus, being able to rebuild everything is a huge bonus for long-term use."
Eagle 90 Transmission is mechanical shifting reimagined—bringing the performance pedigree of SRAM's Eagle AXS architecture into a robust, rider-rebuildable system. At the heart is the Full Mount Eagle 90 derailleur, sharing the same hangerless interface as its electronic siblings, with tool-free cage serviceability and replaceable wear parts. It's SRAM’s most rebuildable derailleur yet, built to take hits and keep going.
A forged aluminum crankset anchors the system with E-MTB-ready stiffness and drive unit-specific offsets, while the XS-1275 T-Type cassette offers a 10–52T range and full X-SYNC tech for smooth, confident shifts under load. The system pairs with a premium aluminum Eagle 90 mechanical shifter, featuring stealthy ergonomics and a crisp double-click actuation. Whether you’re hammering on the pedals or wrenching in the garage, this groupset is built for those who demand control, durability, and a clean, intuitive setup.
