Clean the surface of the rim with a light degreaser and finish with rubbing alcohol. No residue or moisture should be on the rim before applying Velotape.
Starting in the center of the rim at the join opposite the valve hole, begin to apply the Velotape. Ensure the tape is seated in the center of the rim with no air bubbles. The tape must completely cover all of the spoke holes.
For applications under 45 psi (3.1 bar), tape once completely around the rim, pulling the tape tight. Overlap past the join by 2 to 3 inches (5 to 8 cm), and cut with sharp scissors. For applications over 45 psi (3.1 bar), tape twice completely around the rim.
Using a pointed punch or Phillips screwdriver, carefully poke a hole through the Velotape at the valve hole.
Remove the lock nut and washers from the provided valve. Insert the valve into the valve hole, matching the contour of the valve's rubber base to the contour of the rim's taped web. Install one or both provided washers onto the valve stem*. Install the lock nut on to the valve stem. While pressing on the valve's rubber base with your thumb, tighten the lock nut as firmly as possible by hand.
*The white nylon washer is provided for shallow section rims, like the Velocity Dually.
It provides extra spacing so the lock nut does not bottom out on the valve stem's threads prematurely. If you are installing the valve on a deeper section rim, use either the nylon washer, the stainless steel washer, or both.
