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.

• Two alloy large cogs and a full alloy spider eliminate unwanted weight
• Ramped cogs aid in shifting under load
• Continuously molded construction maintains straightness and durability
• Compatible with standard HG freehub bodies and 10-speed chains
