Does anyone own a pump with this valve on it? I just bought a Axiom Dominate Air DLX Gauge from my lbs and can't get it to lock down on my presta valves. Any tips? I don't even get how this design works, maybe if I had a better understanding I would be able to get it to work.
Sometimes, the "nut" that holds the rubber of the valve head is adjustable for presta and schreder. Try tightening this down to compress the rubber further before throwing the valve. On some, you need to take this part completely off and flip it around to convert to presta.
