INSTALLATION: 1. Remove the valve cap, lockring and o-ring from the valve stem. 2. Select the correct rubber base for your rim. Is your rim curved, use the circular rubber base and select the right width. Is your rim square; use the square rubber base. Make sure the base is slid all the way to the bottom of the valve before installation. 3. Push the valve through the valve hole in the rim from the outside towards the center. Place the o-ring over the tip of the valve and slide down until it sits on the rim. 4. Thread the lockring onto the valve and tighten it against the o-ring and the rim. 5. Use a 4mm Allen Key in the base of the valve to hold it on the inside and push the base of the valve against the rim bed. At the same time tighten the lockring until it is hand tight. It is okay if the o-ring is squeezes out slightly, this indicates an airtight seal. Do not overtighten the lockring to avoid leaks. 6. If you choose to ride with valve caps, choose either the 2 black ones or replace one with the purple valve cap with the core removal feature on your other wheel.
