Ride anywhere with this wide range XG-1275, 10- to 50-tooth Eagle cassette that provides the right gear. Fast on the flats. Control on the climbs. Dictate your own pace, anywhere. Only Eagle technology is the 1x drivetrain engineered for infinite freedom. FULL PIN technology uses lightweight, stamped steel cogs held together with high-strength stainless steel pins. The result: a cassette that's light and strong. The open design similar to our X-DOME cassette aids in mud clearance, giving you cleaner shifting performance and longer component life. New X-GLIDE 2 improves both inboard and outboard shifting, as well as chain retention.
