krazy-eyes
Race Dog
mountainbikes have been using these for a while now.
it is they way the extrusion is designed that keeps the spoke nipples in its own air permeable "compartment", while the part of the rim in contact with the tube is airtight with only a hole for the valve.
why dont we get this for motorbikes???
