The basis of every Eagle drivetrain is its chain-and the NX Eagle chain is designed and manufactured using genuine SRAM's Eagle architecture, so it is fully compatible with every other component in the Eagle ecosystem. The NX Eagle chain features solid pin construction, Eagle PowerLock, and smooth, efficient shifting that you can count on every time out.
SRAM's Chain Tech
PowerLock
SRAM chain engineers developed PowerLock as a tool-free, easy, and consistent way to connect their chains. While PowerLock does not require special tools for installation, the especially tight tolerances of 10- and 11-speed drivetrains result in the PowerLock being good for one application only.
Eagle
Eagle Technology represent SRAM's newest 1x drivetrain tech. Eagle is a lighter, simpler, more durable, and easier-to-use drivetrain. Featuring all-new 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. SRAM's Eagle lineup also provides an expanded gear range of 520%, which is equal to 2x11 drivetrains.
FlowLink
Ultra-smooth inner plates are completely devoid of square edges, resulting in a chain that engages the cassette and chainring with far less friction, giving you quieter performance and better wear life. The design allows a narrower profile that can withstand greater angles and also allows for a flatter outer plate, meaning more consistent chain riveting and enhanced overall strength.
