The XX Eagle T-Type AXS™ 12-Speed rear derailleur foundationally changes the relationship between cassette and derailleur. Engineered as integrated, interdependent transmission components, the T-Type derailleur mounts around the wheel axle itself, contacting the cassette directly with a first-of-its-kind Hangerless Interface. Its game-changing Full Mount attachment method creates a far stronger connection and grips both sides of the frame. This XX T-Type rear derailleur features the same intuitive pairing and set-up procedure as Eagle AXS™ derailleurs. - Tucked-in profile houses replaceable skid plates that enhances dependability in high-pressure racing environments - To further its performance, the lower pulley called "Magic Wheel" keeps spinning if an object becomes lodged - Features an overload clutch, accommodates common maintenance and features that real world riders really appreciate - Exceptional shifting performance and unprecedented strength - Aluminum cage - Battery Not Included

Instantaneous shifts from a single touch even while under World Cup-winning chain loads recorded in the heat of racing and affirmed in the test lab. Tested to IP69K water and dust proofing standard so whatever race day brings, you’re ready. - XC focus and trail ready - Carbon cage - Ti hardware - Rainbow colorway - Eagle technology - Overload Clutch protection - AXS enabled componentry software that makes it possible to both program and personalize new SRAM and RockShox components - System is completely water and dust proof to IP69K - Eagle AXS is designed to work with X-DOME Eagle cassettes only, providing the most precise, silent, and reliable shift performance available. - Battery sold separately
