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

The Advent MX G-Series cassette is the smoothest shifting, most durable cassette that they've ever made. That all starts with SpeedRamp, a series of discrete shifting ramps that move the chain quickly, quietly, and precisely under load. The cogs themselves have been upgraded as well: the profile has widened to 1.8mm, and the first seven cogs (11-28) have been constructed using full chromoly steel, helping to outlast even the most robust competitors.

• SpeedRamp technology delivers faster, quieter shifting
• Thicker chromoly steel cogs from 11t to 28t provide a 500% durability increase over hi-tensile steel while the aluminum spider, 42t cog and 50t cog offer valuable weight savings
