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

The microSHIFT Advent MX G-Series is a premium, high-durability 11-speed mountain and e-bike cassette featuring a wide-range 11-50T gear spread. Engineered with SpeedRamp technology—utilizing 64 discrete shifting ramps—it delivers fast, exceptionally quiet, and precise gear changes under heavy pedaling loads. Built to outlast the competition, the first seven cogs are constructed from thick, full chromoly steel for a massive durability increase, while the ultra-wide 42t and 50t climbing gears are machined from lightweight alloy to maintain an overall weight of just 485g.
