Why We Like The GX Eagle AXS Rear Derailleur

Built with tested perfection, the SRAM GX Eagle AXS Rear Derailleur is the latest and greatest in trickle-down technology. Cross-compatible with all other AXS products on the market, this innovative wireless tech introduces a more manageable price point. We’re beyond excited to install the new derailleur on our bikes with the same upgrades many professionals have only just started to enjoy. Simpler than the mechanical version, the new derailleur is compatible with both the 10-50t Eagle cassette as well as the latest 10-52t cassette. AXS battery and charger are sold separately.
