Stan's No Tubes Freeride Rim Strip
Stan's Freeride 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!
The Freeride rim strip will fit most freeride rims that are 27 - 34mm wide.
