With 10 speeds, 11 48t range and evenly spaced gear steps, the ADVENT X cassette allows riders to shift less often to find the right gear, while still having enough range to ride what they want. Fewer cogs also means less weight, a wider chain for better mud shedding it even fits on standard 10 speed freehub bodies so you don't need to buy new wheels for no reason. In short, it's everything you want in a high end drivetrain.
