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.Based on the X-DOME concept of the XX1, the 12-speed Sram Eagle XG-1275 cassette offers new features creating a smoother, quieter system with improved shift performance. Details : 12 speeds 10-50 teeth (10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 50). Bearings and ratchet mechanism stabilized by an XD hub body. Optimized gear changes over the entire range. Compatible only with a 12-speed transmission. New technologies offering greater long life and weight gain. Weight: 450 g.Technology : X-DOMEX-DOME technology creates a rugged, precise and incredibly light cassette. The open structure allows the sludge to be emptied and consequently improves the gear change performance and the service life of the components.X-Glide 2X-GLIDE 2 is the new generation of SRAM X-GLIDE technology optimized for the EAGLE 12-speed cassette. It provides fast and precise gear change performance across the entire development range, and increases chain retention on the largest sprockets. XD Cassette BodyThe XD is a cassette body which allows, by design, to use a small pinion of 10 teeth and which guarantees an improved interface with the cassette.
