The XG1150 incorporates SRAM's FULL PIN™ technology uses eleven lightweight, stamped steel cogs held together with 123 high-strength stainless steel pins. The result: a cassette that's light, durable and equipped with SRAM's super wide 10-42t gear range that's a perfect fit for any ride. The open design similar to our X-DOME™ cassette aids in mud clearance, giving you cleaner shifting performance and longer component life.
