The strongest system is a chain with no weak links. Eagle™ chain links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear. This design also allows for a flatter plate, which means more consistent chain riveting and greater overall strength. And it’s also the biggest contributor to the ultra-smooth, precise, durable and quiet performance found in the 10-50 tooth cassette and X-SYNC™2 chainrings. Installation is made easy with a dedicated 12-speed Eagle quick link.
