SRAM Eagle 90 T-Type Mechanical Derailleur – Durable, Rebuildable, Ready to Ride

The SRAM Eagle 90 T-Type Derailleur is a next-generation mechanical derailleur built for riders who want modern drivetrain architecture without the complexity of electronics. Designed around SRAM’s Full Mount interface, it provides unmatched stiffness, strength, and precise shifting, all while ditching batteries in favor of a simple, reliable cable-actuated system.

SRAM didn’t just bring mechanical shifting back—they made it better. The Eagle 90 derailleur is fully rebuildable, with nearly every component replaceable thanks to SRAM’s service kits. Whether you’re hitting rough enduro trails or grinding through daily mileage, this derailleur offers solid, consistent shifting and a strong clutch to keep chainslap under control. It’s also compatible with the full suite of T-Type Transmission components, allowing riders to upgrade or mix and match.
