What Is It?
The SRAM XG-1275 Eagle 10-50T 12-Speed Cassette (Black) is a high-performance 12-speed mountain bike cassette from SRAM's GX Eagle drivetrain range. Designed for riders who demand wide gearing, durability, and precise shifting, it features a 500% gear range with a 10-50T spread, making it ideal for everything from steep technical climbs to fast descents.
Built using FULL PIN™ technology, the cassette uses lightweight stamped steel cogs permanently connected with high-strength stainless-steel pins, delivering an excellent balance of strength, weight, and value. Its open design also improves mud clearance for reliable shifting in demanding trail conditions.
