A chain that’s more than the sum of its hollow pins or its fanatically shaped chamfers. Because it takes more to make a chain XX1 Eagle worthy. XX1 means uncompromising strength at an ultra-light weight with performance consistency and silky smooth, whisper-quiet operation. Now completed with SRAM's all-new Eagle colorsystem setting the aesthetic bar and giving riders color options from Black to Gold to Rainbow, including all-new Copper. Designed and manufactured in SRAM's European facilities, it’s the quietest, strongest, and most wear-resistant chain in the world. 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. Hard Chrome SRAM Hard Chrome chains offer 4x more elongation and wear resistance than other SRAM chains. Thanks to the new finishing process on the inner links and rollers, these chains last longer while offering the same ultimate strength SRAM chains are all known for. X-Sync SRAM X-Sync 1x chainrings provide the highest level of performance and durability. The tall, square teeth edges engage the chain earlier than traditional, triangle-shaped teeth, and the sharp, narrow tooth profile and chamfer edges help manage chain deflection. Designed with mud-clearing recesses on the inner chain links and rollers, this chain offers the best possible performance in muddy conditions.
