Sram XX SL T-Type Eagle AXS 12 speed rear derailleur 2025

The Sram XX SL Eagle Transmission derailleur radically changes the relationship between the cassette and the derailleur. Designed as an integrated, interdependent component of the drivetrain, the T-Type derailleur mounts around the wheel axle, making direct contact with the cassette thanks to a unique hangerless interface. Its revolutionary Full Mount attachment system creates a much stronger connection by securing to both sides of the frame.

The new Transmission derailleurs follow the same intuitive pairing and setup procedure as Eagle AXS derailleurs. Equipped with the Overload Clutch protection system, this model features a compact shape that eliminates anything unnecessary for victory. It requires only routine maintenance and, to further enhance its racing performance, includes a small pulley called Magic Wheel that continues spinning even if an object gets caught in the mechanism.

Additionally, the XX SL Eagle Transmission derailleur features a carbon cage and replaceable protective covers for the upper link and parallelogram, all in an elegant black finish. It delivers unmatched shifting performance, lightweight construction, and unprecedented durability.
