It might look normal from the outside, but the engineering inside this incredible new chain design that 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, and a titanium nitride coating on the gold and black models decreases corrosion and further reduces friction.Things to remember:Eagle™ represents our newest 1x drivetrain technologiesEagle™ is a lighter, tougher, quieter, more durable and more preciseEagle™ features all-new 1x components, engineered for even greater durability and performanceEagle™ has a significant weight advantage over other drivetrains — xx1 Eagle™ weighs up to 300 grams less than 2x drivetrains with similar gear rangeEagle™ technology allows an expanded, optimum, 500-percent gear range — a 20-percent increase over our other 1x drivetrainsEagle™ is a complete drivetrain system that was developed to be an integrated high-performance ecosystem. The engineering and testing that went into the development provide for maximum performance, safety, and long-term durability to ensure a great consumer ride experience. We guarantee this performance when Eagle™ drivetrains are used as a complete ecosystem.
