The Advent MX cassette is the smoothest shifting, most durable cassette that we've ever made. That all starts with SpeedRamp, a series of 64 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.
