If you’re building a high-performance, high-resilience gravel rig—this is your derailleur.

Eleven speeds to rule all the trails. That is the X1 Rear Derailleur's motto. It packs a massive amount of technology into its compact, lightweight aluminum body. This 11-speed gear changer uses a “horizontal parallelogram” design that limits all movement to the horizontal axis, reducing the force it takes to shift. The Type 2 clutch is brilliant. This self-lubricating, one-way roller clutch controls your chain tension to eliminate chain slap and give you smooth, consistent shifts over any terrain. For quicker, smoother, more exact shifting, the large upper pulley's offset design maintains a consistent chain gap across all gears.

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

Occupying a new realm in shifting performance, the redesigned XX1 Eagle derailleur gives no-compromise racers and dream-bike builders a true top-tier option.
