What makes the SRAM X0 Eagle T-Type AXS rear derailleur different?

The SRAM X0 Eagle T-Type AXS Rear Derailleur is competition-grade shifting built for the Eagle Transmission platform, a ground-up redesign that mounts directly around the rear axle instead of a hanger. The Hangerless Interface and Full Mount attachment grip both sides of a UDH-compatible frame and contact the cassette directly, creating a far stronger, more precise connection than any traditional setup. Setup is radically simple with no limit screws or cable routing: prepare, hang, tighten, and let the AXS app handle configuration. An overload clutch boosts durability, and the tucked-in profile keeps rock strikes to a minimum.

When impacts do happen, the replaceable B-knuckle and outer link covers keep the derailleur serviceable, and the design is upgradable to the XX skid plate. This is the X0-tier derailleur, 12-speed with a 52t max and aluminum cage, weighing roughly 466g, and the battery is not included. It is purpose-built for the T-Type ecosystem of Transmission chains, cassettes, and chainrings and is not compatible with standard Eagle drivetrains. Best for riders building or upgrading to Eagle Transmission who want race-proven robustness with full repairability.
