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

The microSHIFT Advent MX G-Series HG Cassette is a purpose-built 11-speed 11-50t cassette for riders who want a wide gear range with crisp, controlled shifting in real trail conditions—especially when shifting under load. Built around SpeedRamp shift features and high-wear chromoly steel cogs where it matters most, it’s a durability-focused option for Advent MX 1x drivetrains on a standard HG freehub body.

• Advent MX-specific spacing - Designed to shift correctly only with microSHIFT Advent MX components for consistent indexing and chain control
• Wide-range 11-50t gearing - Delivers a true bailout gear for steep climbs while keeping an 11t high gear for fast rolling sections
• SpeedRamp shift profiling - Helps the chain move quickly and quietly between cogs, including during higher-torque upshifts
• 1.8mm cog profile - Thicker cog construction for improved resistance to wear and deformation over time
• Chromoly steel cogs (11-28) - High-wear gears use full chromoly steel; microSHIFT states up to a 500% durability increase versus hi-tensile steel
• Aluminum spider with large cogs - Uses an aluminum spider plus 42t and 50t cogs to reduce weight while keeping the biggest gears stable
• Replaceable small cogs - Extends service life by allowing replacement of the most frequently used gears
• Nickel-plated satin finish - Helps resist corrosion and keeps wear less visually obvious over time
• E-bike rated - Approved for e-bike use where drivetrain loads are typically higher
• HG freehub compatibility - Fits standard HG cassette bodies for straightforward upgrades and replacements
