SRAM XX SL Eagle AXS T-Type Rear Derailleur

The SRAM XX SL Eagle AXS T-Type Rear Derailleur mounts directly to the rear axle rather than a traditional hanger — a structural shift that puts the derailleur in rigid contact with both sides of the frame and eliminates one of the most common failure points on a mountain bike. That direct-mount interface, the defining feature of the T-Type system, creates a more precise, repeatable chain line from cassette to derailleur without the flex and alignment headaches that come with hanger-dependent setups.

Wireless AXS shifting means setup follows the same pairing process as other AXS components in the ecosystem — no cable routing, no barrel adjusters. The Magic Wheel lower pulley is designed to keep rotating if trail debris gets caught in the drivetrain, reducing the chance of a mechanical ending your ride. As the flagship of SRAM's mountain drivetrain lineup, the XX SL sits at the top of the Eagle range in both weight and build quality, with materials chosen to cut grams where they matter most on a race-day build.
