Microshift Advent MX G-Series 11-Speed SpeedRamp Cassette (11-50T) - SRAM XD

The microSHIFT Advent MX G-Series is a premium, high-durability 11-speed mountain and e-bike cassette engineered specifically for standard SRAM XD driver freehub bodies. Featuring an expansive 11-50T gear spread, this wide-range cassette utilizes proprietary SpeedRamp technology—consisting of 64 discrete shifting tracks—to deliver lightning-fast, ultra-quiet gear changes under heavy pedaling loads. Built to withstand punishing trail conditions and high-torque mid-drive motors, the first seven cogs are constructed from thick, full chromoly steel for a 500% lifespan increase, while the largest climbing gears are optimized for maximum structural stiffness.
