FAQ

Does the SRAM XX Eagle T-Type derailleur need a derailleur hanger?

No. The XX Eagle Transmission derailleur uses a Hangerless Interface and mounts directly around the wheel axle with the Full Mount system. It requires a UDH-compatible frame, but it replaces the hanger entirely rather than bolting to one.

Is a battery included with this derailleur?

No. This derailleur is sold without a battery. It uses the standard SRAM AXS battery, which is interchangeable across the AXS ecosystem, so you can share batteries between components if needed.

What cassette does the XX Eagle T-Type derailleur work with?

It is built for SRAM Eagle Transmission T-Type cassettes with a 52t maximum cog. Eagle Transmission is a closed system and is not compatible with previous-generation Eagle drivetrains.

What is the Magic Wheel on this derailleur?

Magic Wheel is the lower pulley design that keeps spinning even if a rock or stick gets lodged against it, letting you keep pedaling through debris instead of grinding to a stop or damaging the derailleur.

Best For

XC and trail racers running a SRAM Eagle Transmission drivetrain who want the durability and direct-mount strength of T-Type with serviceable, replaceable wear parts built to survive aggressive, high-pressure riding.
