microSHIFT Advent MX G-Series Cassette - 11-Speed, 11-50t, Aluminum Spider, Silver/Black, For HG Driver

The microSHIFT Advent MX G-Series cassette is an 11-speed, 11-50t wide-range block for 1x mountain drivetrains, slotting onto a standard Shimano HG freehub. Cog steps run 11-13-15-18-21-24-28-32-36-42-50, giving a climbing gear close to a 12-speed setup without a new hub. Chromoly steel cogs handle the 11 to 28 tooth end while an aluminum spider carries the 42 and 50 tooth cogs to cut weight, for a total of 485 grams. SpeedRamp shift gates and a 1.8mm-wide tooth profile give crisp, durable shifts. The silver and black finish suits budget and backup 1x builds.
