The Eagle chain has been completely re-engineered, and is produced with new manufacturing technology. The GX Eagle chain is designed with SRAM s Eagle geometry and features solid pin construction, Eagle PowerLock and smooth, efficient shifting that you can count on every time out. The all-new Eagle PowerLock chain connector with Flow Link technology provides better chain-guiding and increased longevity. Unique features and design also provide significantly improved wear resistance on Eagle cassettes and rings. SRAM chain engineers developed PowerLock as a tool free, sure, and consistent way to connect their chains. While PowerLock does not require special tools for install, the especially tight tolerances of 10, 11 and 12-speed drivetrains mandate that each PowerLock is good for a one-time application only.The Flow Link technology utilises ultra-smooth chain inner-plates that are completely devoid of square edges, resulting in a chain that engages the cassette and chainring wit
