I got the Lezyne cnc floor pump for Christmas. Love the way it looks and it pumps sooooo smooth. HOWEVER, I can't for the life of me figure out how to unscrew the chuck without pulling the valve core on the tube's stem. Makes it kind of useless.
I talked to a local mechanic and he just started laughing. He said that Lezyne's official solution was to try screwing the valve core in tighter and, if (when) that doesn't work, to wrap a few of the valve's threads with teflon tape. Sure.
