Advent MX H-Series HG Cassette - 11-Speed, 11-50t

microSHIFT Advent MX H-Series HG Cassette delivers a wide-range 11-speed 11-50t gear spread for modern trail and MTB builds that need low climbing gears without giving up a usable top end. Built around SpeedRamp shift-ramp profiling, it’s tuned to move the chain quickly and predictably—up or down the cassette—so shifts stay controlled when torque is high on steep or technical climbs.

• 11-50t wide-range gearing - Expands climbing capability and cadence control for steep grades, loaded riding, and big-elevation days
• SpeedRamp shift architecture - Dedicated ramp shapes for upshifts and downshifts help maintain fast, quiet shifts under load
• 2-layer ED black finish - Adds corrosion resistance for wet-weather trail riding and frequent wash cycles
• Aluminum 50t cog - Reduces weight at the largest cog where it matters most for rotational mass
• HG freehub compatibility - Fits standard HG cassette hub bodies for straightforward upgrades and replacements
• Replaceable small cogs - Extends service life by allowing replacement of the most-worn sprockets instead of the entire cassette
• Advent MX-specific compatibility - Engineered to match microSHIFT Advent MX drivetrain spacing and shift performance
