The SRAM GX Eagle Transmission derailleur redefines robustness and serviceability in electronic shifting. Engineered with real-world riding in mind, it features a reconfigured gearbox and a revised battery position to reduce impact vulnerability. For added longevity, key components like the protective skid plates and two-piece outer link are replaceable—enhancing repairability and durability. A steel inner cage reinforces the derailleur’s structural integrity, while the new tool-free cage and clutch assembly allows for fast, no-tool upgrades or replacements. This makes the GX Eagle Transmission the most serviceable derailleur SRAM has ever produced, built to endure aggressive trails and daily abuse.

Like all Eagle Transmission models, the GX version uses the groundbreaking Hangerless Interface, mounting directly around the wheel axle and contacting the cassette with no derailleur hanger needed. Its Full Mount system further boosts structural security by clamping both sides of the frame. Set-up is simple and adjustment-free, utilizing SRAM’s proven AXS wireless protocol and intuitive pairing process. With compatibility for 12-speed, 1x drivetrains and T-Type chain technology, the GX Eagle Transmission offers high-end performance without compromise. Rugged, intelligent, and easily serviceable, it’s designed to thrive in the harshest riding conditions.
