The Sram XX Eagle AXS rear derailleur is a real revolution for MTB drivetrains. Its T-Type Full Mount system, which mounts around the wheel axle and grips both sides of the frame, provides exceptional strength. With the aim of making it even less vulnerable, it features a Magic Wheel lower pulley that allows the star cage teeth to disengage when a branch blocks them, enabling the chain to continue turning. X-Sync technology ensures better chain retention. Overload Clutch technology is also a new feature, as it allows the derailleur to disengage when overloaded to prevent it from breaking.Working in sync with Eagle T-Type cassettes, it allows you to maintain maximum tooth engagement on the sprockets when changing gears for smoother transmission even when you're pushing hard on the pedals.An aluminium body and cage and titanium hardware make for a robust, high-performance derailleur weighing only 450g.This derailleur is only compatible with Sram Eagle T-Type cassettes.
