Mechanical shifting at its finest—Eagle 90 delivers the dream and then some. Sharing the same Full Mount derailleur architecture as its AXS Transmission counterparts, it’s undeniably rugged and reliable. The derailleur body features replaceable outer and inner parallelogram links, skid plates, and a tool-free threaded cage assembly, making it the most serviceable derailleur SRAM has ever created.

At the core of the system is a sleek, forged aluminum DUB crankset, paired with a signature silver T-Type chainring that includes removable bash guards. True to Eagle Transmission’s reputation, shifting under load is effortless thanks to the XS-1275 T-Type cassette with full X-Sync technology and a premium double-click T-Type Actuation mechanical shifter.

For the DIY enthusiast, Eagle Transmission offers an incredibly simple four-step setup: Prepare. Hang. Tighten. Route. With no limit screws, no B-tension adjustments, and no guesswork involved.

Built to push your limits, the Eagle 90 Transmission delivers an unmatched ride experience for every rider.
