What makes the SRAM GX Eagle T-Type AXS rear derailleur different?

The SRAM GX Eagle T-Type AXS rear derailleur is engineered specifically for the Eagle Transmission (T-Type) platform, a fundamentally different architecture from standard Eagle. It mounts via the Hangerless Interface, gripping both sides of the frame with Full Mount attachment for a stronger connection with no hanger required. Setup is radically simple: no adjustment screws, no cable routing. Prepare, hang, and tighten, with the AXS app handling all configuration. The revised battery position and reconfigured gearbox protect against impacts, and replaceable skid plates and outer link make it the most repairable Eagle derailleur ever made. A tool-free cage and clutch assembly is both removable and upgradable.

GX T-Type is purpose-built for the Transmission ecosystem: T-Type chains, T-Type cassettes, T-Type chainrings. It does not use a standard derailleur hanger and is not compatible with standard Eagle drivetrains. If you are building or upgrading to Eagle Transmission, this is the GX-tier derailleur to spec.
