Upgrading to Eagle Transmission has never been more straightforward. The GX Eagle Transmission Upgrade Kit is your entry point into the AXS ecosystem of wirelessly connected components, designed specifically to make the move from mechanical to wireless as simple and seamless as possible.

The kit includes an AXS-enabled derailleur body, AXS Battery, and AXS Pod Controller, allowing you to retain your existing threaded cage assembly and mount bolt from any Eagle 90 or Eagle 70 derailleur. By transferring these parts onto the new GX Eagle Transmission derailleur body, you maintain component continuity while unlocking the precision, consistency, and modern performance of T-Type Transmission.

The included Eagle T-Type PowerLock ensures secure chain re-installation, giving you added peace of mind through a straightforward upgrade that transforms your drivetrain into a fully integrated, wireless system built for the hangerless (UDH) interface.
