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. Purchase its silver counterpart here
