Mechanical shifting at its absolute best. The Eagle 90 delivers a robust and rebuildable drivetrain inspired by its AXS Transmission counterparts. Its Full Mount derailleur architecture provides exceptional durability, while the replaceable parallelogram links, skid plates, and tool-free threaded cage assembly make it the most serviceable derailleur SRAM has ever built. At its core is a forged aluminium E-MTB crankset with a drive-unit specific T-Type chainring, engineered for uncompromising strength and performance. Designed for effortless precision, the Eagle 90 offers smooth shifting under load, full X-SYNC technology, and an intuitive four-step setup — Prepare. Hang. Tighten. Route. Built for riders who demand mechanical perfection with trail-ready resilience.
