PH wrote:How do you stop them unscrewing your valves? I watched someone pump a tyre up three times, each time the valve unscrewed when he tried to remove the pump. He admitted defeat any used someone else's pump.
Not only do I have the mini Lezyne, I have a Lezyne track pump too.
The valves only unscrew if you
1. don't have the valve core screwed tight enough.
2. you unscrew the Lezyne connector non-square.
It's easy peazy, all you need to do is do it properly.
Since going over to Lezyne and the Air Bleed System (ABS), I wouldn't use anything else. I cannot recommend them highly enough.
