The GX Eagle Transmission derailleur delivers everything an Eagle Transmission derailleur possibly can, and then some. It features a revised battery position to better protect itself from impacts and to maintain crisp shifting and striking appearance throughout its entire lifespan. Hard chargers can replace both its protective skid plates and two-piece outer link. It also features a tool-free cage assembly - so it&&';;s both removable and upgradeable too. With a steel inner cage that adds even more robustness, it&&';;s been built for riders of the real world. Just like all Eagle Transmission derailleurs, it&&';;s been engineered with a first-of-its-kind Hangerless Interface, mounting around the wheel axle itself and making direct contact with the cassette with no hanger required. - T-Type compatibility- Revised battery position, reconfigured gearbox, replaceable skid plates and outer link, tool-free cage, and clutch- Install and pair via the reliable and familiar standard AXS set-up and pairing procedure- Hangerless Interface, Full-Mount attachment method- Radically clear setup process, no adjustment required- AXS battery and Pod controller are sold separately
