It might look normal from the outside, but the engineering inside this incredible chain design is anything but normal, and it 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.

New Super Record 12 Speed chain: slim, robust, smooth and precise. The chain, in all its apparent simplicity, plays a critical role in the cyclist's safety and in optimizing the entire transmission mechanism. The new Super Record 12 Speed chain also had to be redesigned from scratch to work with all the other new transmission components. Therefore, the first and most important objective was reducing its overall dimensions. Its width is now 5.15 millimeters, thanks to the new pins which are perfectly aligned with the links’ outer surfaces. The second objective was safeguarding its performance. This was achieved thanks to the Ultra-link system that makes the chain safe and durable, and a special treatment that guarantees extreme smoothness and precision shifting.
