Mechanical shifting at its finest. The Eagle 90 brings the precision and robustness of SRAM’s AXS Transmission architecture into a fully mechanical system. Its Full Mount derailleur design ensures unrivalled strength and serviceability, with replaceable parallelogram links, skid plates, and a tool-free threaded cage assembly—making it the most rebuildable derailleur SRAM has ever produced. At its core is a forged aluminium E-MTB crankset with a drive-unit specific T-Type chainring, delivering power and durability in perfect harmony. Shifting under load is seamless thanks to the XS-1275 T-Type cassette with full X-SYNC technology and a premium double-click mechanical shifter. With a revolutionary four-step setup—Prepare. Hang. Tighten. Route.—Eagle 90 eliminates limit screws, b-tension, and guesswork, giving riders a refined and resilient drivetrain ready for any adventure.
