X0 Eagle T-Type AXS Rear Derailleur
Best high-performance drivetrain upgrade for serious mountain bike racers.
Experience a fundamental shift in your drivetrain with the SRAM XX SL Eagle T-Type AXS 12-Speed rear derailleur. This component redefines the cassette and derailleur relationship by engineering them as integrated, interdependent parts. It features a revolutionary Hangerless Interface, mounting directly around the wheel axle and contacting the cassette directly, requiring a frame with a UDH interface. The Full Mount attachment method creates a much stronger connection by gripping both sides of the frame. Built for race-day performance, it includes an overload clutch and a streamlined profile. For easy maintenance, it features a "Magic Wheel" lower pulley that keeps spinning if an object gets lodged, alongside a carbon cage.

Know before you buy
No, this derailleur is exclusively compatible with frames that feature the Universal Derailleur Hanger (UDH) interface. It mounts directly to the frame, so you must verify your bike's compatibility before purchasing.
By mounting directly around the wheel axle, the Hangerless Interface creates a much stronger, more precise connection between the derailleur and the cassette. This design eliminates the traditional hanger, which significantly improves shifting performance under load and increases overall durability.
The derailleur is equipped with an overload clutch that allows the motor to disengage upon impact, protecting the internal components from damage. Additionally, the 'Magic Wheel' lower pulley is designed to keep spinning even if debris gets lodged in it, helping you keep moving on the trail.
Yes, the carbon cage is engineered for race-day performance, balancing a lightweight profile with the structural integrity needed for demanding terrain. While it is built to be light, it is designed to withstand the rigors of competitive mountain biking.
Yes, the system is designed for serviceability. You can replace the outer link and the b-knuckle cover, which helps extend the life of the derailleur without needing to replace the entire unit.
Traditional derailleurs attach to a hanger, but the Full Mount system grips both sides of the frame. This creates a significantly more rigid connection that improves shifting accuracy and provides better resistance against impacts.
