Really? I've never had that issue. In fact, I never screw down my presta valves, they're always open.Originally Posted by Tuckervill

But with the Presta valve open, anything brushing against the pin just allows air to escape. I'm pretty clutzy and my family is not always careful when they are loading the car or what have you. So I wouldn't leave it open because the boy would put his helmet on it or something.
Oh well.

I have been curious about this. Can you use either a presta tube or a Schraeder and vice versa? Does that just depend on the opening of your wheel or what?

No, you can't. You can't use a presta in a schraeder because the tube will tear around the sharp hole. You can't use a schraeder in a presta because the stem won't fit through the hole. Originally Posted by sandra

Can you go to your LBS or some local bike club or REI and get a tube change demo? Our local REI gives demos every spring, but I would think they'd do it anytime if someone asked.
Fixing a flat is EASY - but one of those things that can be really hard to figure out in the first place.
there has to be a youtube video or something!

THERE IS a video. I've watched it. Maybe someone here will know the link.

I've never seen a video, I used the Park Tools step by step the first time I changed one.

LOL. Whatever works, it's just been my experience that I typically don't have issues with leaving them completely open. It's funny though, whenever someone notices it they bend down to close it! Originally Posted by Tuckervill

this is a great step-by-step guide you can print out and practice with.
I went to a trek wsd tour and watched the tour person do it, and they gave us this guide.
