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

microSHIFT Advent MX G-Series XD Cassette in 11-speed 11–50T delivers a wide-range drivetrain option for riders who want low climbing gears without giving up a fast 11T top end. Built specifically for Advent MX shifting, it pairs load-friendly ramp shaping with durability-focused materials for consistent performance on trail bikes, hardtails, and e-MTB applications that demand higher wear resistance.

• Advent MX-specific spacing - Designed to shift correctly only with microSHIFT Advent MX components for precise indexing and dependable performance under load
• XD driver compatibility - Fits XD freehub bodies for modern MTB wheel builds that support small 11T top cogs
• 11–50T wide-range gearing - Provides a 455% range to keep cadence manageable on steep climbs while preserving speed on flatter sections
• SpeedRamp shifting features - Discrete shift ramps help the chain move quickly and quietly, especially when the rider is still putting power through the pedals
• Durability-first small cogs - Thicker chromoly steel cogs from 11–28T and a widened 1.8mm cog profile are engineered for long wear life in gritty conditions
• Smart weight distribution - An aluminum spider plus alloy construction on the 42T and 50T cogs helps control weight where it matters most on a wide-range cassette
• Nickel-plated satin finish - Reduces visible wear and helps resist corrosion over time
• E-bike rated - Specified for higher-torque use cases that accelerate drivetrain wear
• Replaceable small cogs - Extends service life and can reduce long-term replacement cost for riders who wear out the smallest cogs first
