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. Groundbreaking chain design and technology The Eagle™ chain has been completely re-engineered, and is produced with new manufacturing technology. Eagle™ PowerLock® chain connector with FLOW LINK™ technology provides better chain-guiding and increased longevity The Eagle™ chain is the quietest, strongest and most wear-resistant chain in the world Unique features and design also provide significantly improved wear resistance on Eagle™ cassettes and rings
