SRAM Rear Derailleur GX Upgrade Kit

The SRAM Rear Derailleur GX Upgrade Kit is a simple path from mechanical shifting to fully wireless Eagle Transmission performance. This kit provides the key AXS components needed to upgrade an existing Eagle 90 or Eagle 70 derailleur while keeping your threaded cage and mount bolt. It delivers precise wireless shifting, consistent performance, and full compatibility with SRAM’s hangerless UDH ecosystem.

Key Features and Benefits:

• AXS-enabled GX Eagle Transmission derailleur body included: This replaces the mechanical derailleur core with a wireless AXS unit that communicates directly with the Pod Controller. The result is consistent and accurate electronic shifting that removes cable stretch and contamination from the system.
• Retains existing threaded cage assembly and mount bolt: This allows reuse of parts from Eagle 70 or Eagle 90 derailleurs. The benefit is lower upgrade cost and reduced waste while keeping familiar hardware in service.
• Includes AXS Pod Controller: This wireless controller replaces mechanical shifters with ergonomic button input. The benefit is clean cockpit layout and fast shift response, resulting in simple, reliable control in all weather.
• AXS Battery and Charger included: The removable rechargeable battery powers the derailleur with long service intervals. This ensures dependable shifting across many rides and easy charging when required.
• Eagle T-Type PowerLock supplied: This secure quick-link allows safe chain removal and refitting during installation. The outcome is a straightforward conversion process with reliable chain connection.
• Compatible only with UDH hangerless frames and T-Type components: This ensures correct alignment and full system integration. The result is stronger drivetrain durability, improved shifting under load, and long-term reliability.

Wireless shifting reliability and clean integration are key priorities for riders moving away from mechanical systems. This kit provides the essential hardware to complete that change while keeping selected existing components. The AXS system removes cable friction and setup complexity, while T-Type compatibility ensures accurate shifting under load and strong drivetrain durability.

Upgrade your drivetrain with a focused and cost-effective move into the AXS ecosystem. This kit provides the essential components needed to modernise shifting and bring your Eagle setup in line with current Transmission technology.
