Stan's Standard Rim Strip converts standard tubed wheels to tubeless so you can reap the benefits. Going tubeless allows you to run low tire pressure for better traction while drastically reducing the chances of a flat. Stan's rim strips create a tight seal with the tire bead, reducing the instances of "burping". Plus, you won't miss dealing with flat tires and you'll save money on tubes!
Standard Rim Strip fits most 26-inch and 24-inch rims that are 21.5 - 25mm in width
