Stan's No Tubes All Mountain 29er Rim Strip
Stan's All Mountain 29er 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 All Mountain 29er rim strip fits 29-inch rims that are 25 - 28mm wide.
