XX1 Eagle Copper Chain Goodr X-ACTUATION™ technology eliminates slop andThe 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 for more consistent chain riveting and greater overall strength. It's also the biggest contributor to the ultra smooth, precise, durable, and quiet performance found in the 10 50T cassette and X SYNC 2 chainrings.
