It might look normal from the outside, but the engineering inside this incredible chain design makes possible a gear range previously found only in 2-chainring drivetrains. And it’s also the biggest contributor to the Eagle drivetrain’s ultra-smooth, precise, durable, and quiet performance. The Eagle chain’s links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction, and wear on chainrings and cassette cogs. This design also allows for a flatter plate, which means more consistent chain riveting and greater overall strength. Hard Chrome technology extends the chain’s optimal performance life.

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 2×11 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.
