SRAM Eagle GX 12-Speed Rear Derailleur
Strong and versatile, the SRAM Eagle GX 12-Speed Rear Derailleur is designed to deliver smooth shifting for your cross country, trail, or enduro bike. Designed for use with up to the latest 52t SRAM cassettes, it is compatible with all other components from the Eagle mechanical ecosystem. An all-new cage design improves chain management, providing better chain retention for precise shifting. A roller bearing clutch reduces chain slap for a silent ride on rough trails, without sacrificing shifting performance.
Robust and refined, the GX derailleur delivers crisp shifting even under load, perfect for sprint finishes and technical climbing. A cage lock allows for easy wheel removal and chain installation and X-Actuation ensures consistent performance across the whole range of gears.

About SRAM
Reinventing the ride, one component at a time.
Founded in Chicago in 1987 with a single product — Grip Shift — SRAM has spent four decades reinventing how riders interact with their bikes. From the first wireless electronic groupset to today's AXS ecosystem, the brand keeps asking the same question: how do we make the next ride better?
Wireless. Configurable. Ride-aware. SRAM's AXS platform replaces a tangle of cables and proprietary protocols with a single, app-driven ecosystem that spans road, gravel and mountain. Components talk to each other and to you.
