Sometimes less is more. 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.
