any time! and just an fyi, if you're running tubes, some tubes you can replace the valve core and some you can't (they're fixed)... if that's the case, you'll need to replace the entire tube.

@TivonSanders Жыл бұрын

I really needed this video. I've been seeing so many people "remove" the core the ghetto way (which was them only removing the lock nut so the small pin can move freely into the tube) to inject sealant in, but that wasn't "professional" enough for me. This is the proper, and best way. Thanks!

@TheMarkList 2 жыл бұрын

Justin, it depends on your tube and/or if you're running tubeless. A new core is less than a buck and super easy to replace. Some tubes you can replace it. Just be careful not to twist too hard as to damage the tube - if it is indeed removable. I've been running tubeless on my gravel, enduro and dh bike and haven't used a tube in ages... so I'd have to actually grab a tube to check and confirm it's doable! Hopefully it is!

Hey cool video. I’ve got a presta valve core that is removed but the air won’t come out of tire. I can’t put air into tire with core installed either. Is there something that is in the tire to keep air from coming out when removed? And when I put core in the air won’t go into tire. Which is why I removed the core in first place. I’ve never had this happen before.

@TheMarkList Жыл бұрын

Take a 2mm Allen wrench and shove it into the valve once the core is removed. Most likely it's clogged with dried sealant. I'll post a short today on how to do it.

thanks this really helped. My Presta valve broke but the tire did not go down, It stayed sealed and I drove 50km and the tire stayed up all the way. Now I know how to change the core I can take a core from my spare and just replace the core and keep on going. Great video. Sometimes it is hard to get the pump on a tire is there an extender that you can put on a tire so you are away from the rim and then put the pump on?

@TheMarkList 2 жыл бұрын

I do believe they make an extension you can screw on an existing valve stem.. ideally, get a longer stem next time which helps with deep rim profiles.

@rangersmith4652 2 жыл бұрын

Reason tells me a bent presta valve stem can probably be coaxed into being straight again, perhaps not perfect but certainly usable. If you have a balky or leaky non-removable core -- and many cores are non-removable -- it might make sense to try straightening it before tossing the whole tube. Care must be taken, of course, because it's made of brass, a very soft metal that work hardens and becomes brittle. It if breaks off, you're replacing it for sure.

Absolutely! Really depends on the situation. They do break a lot when trying to bend them back!

While unscrewing my presta pump adaptor the valve core blew out at high pressure. Given the tight fit of the adaptor that you screw on what keeps it from acting as a valve core wrench and loosening the valve core each time? It freaked me out blowing out at 85psi and both the stem and my adaptor went flying in the backyard. Shouldn’t the thread go the opposite direction to avoid this?

@TheMarkList Жыл бұрын

If you're using an adapter for your pump to fit, don't screw it on so tight. Just snug. The valve core should be nice and tight so as not to accidentally unscrew.. Like I think happened with you.

Hi mark. My valve core is stuck and won’t let me deflate. If I remove the valve core whilst fully inflated am I going to get loads of sealant spewing out?

Spin the wheel so the valve is in the top (12 o clock) position. Then take the valve out. The sealant will be at the bottom (6 o clock position) and should have minimal spray or leakage. I'll do a short on it today.

@TheMarkList Жыл бұрын

So most mountain bike tires run a tubeless setup as do most of the newer road bikes/gravel bike wheels and tires. A new valve core is about a dollar and takes 30 seconds to change. A tube is more expensive, heavier and takes longer to install and change. Also, you're more likely to get a pinch flat with a tube then with a tubeless set up. A new tube certainly is an option, but with most modern bikes going to a tubeless setup, it's bit antiquated to replace it with a new tube.
