microSHIFT Advent MX G-Series 11-Speed Cassette 11-50t, Aluminum, Chromoly
The Advent MX G-Series cassette is the smoothest shifting, most durable cassette that they’ve ever made. 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.
