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. - compat - speed (cn): 12s-eagle - chain length (links): 126 links - color - outer link: silver - color - inner link: silver - chain connector: powerlock - inner link finish: chrome plated - outer link finish: nickel - pin variant: hollow pin - pin treatment: chrome hardened
