MASSIVE bike upgrade!

I mean, I'm not a valve guy, but... I reckon that is a seriously good looking (new) valve

@Argie it has one or two tiny issues- it's harder to let air out of the tire, and regular presta pumps work but think the tire pressure is higher than it actually is- but the'yre a breeze to install and the top won't bend like the top of as Presta loves to do.

Are there different pumps or adapters available? I’m interested in these but already support 2 valve formats among our bikes.

@wjcstp a standard Presta pump works with these, with the caveat that the pressure gauge read about 6-7 pounds higher. The valve uses a spring to hold itself closed, and that's the apparent relative change in pressure. I bought an adapter for my floor pump that gets rid of that problem, but I'm not going to worry about my travel pump until I'm sire I'm sticking with these.
