Great video, thanks. The only video I've seen that actually takes the Presta valve apart and explains how it works. Best way to understand how things work is to take them apart!

[@jakerazmataz852]

Not all come apart.

[@richardkandalec4128]

Very informative. Most people do not realize you must push the stem in slightly to break the seal which you explained twice. Also, I learned to not tighten the nut down too tight along the stem against the rim because any slight movement of the tube inside the rim will cause the stem to be torn away from the tube.

great video! I discovered earlier today, that when I got my bike tuned, they installed a presta valve. Riding bikes for over 30 years, I didn't understand wtf was going on. luckily, the bike pump in the complex's bike room had a dual head, so I figured that part out. I didn't understand what I specifically had to do to get air to stay in the tires. I was MAD. also glad that I didn't walk up to the gas station and find that I could not get air. thank you!

In a pinch, you can cut the tip of the Presta valve plastic cover cap (dust cap) and it will serve as a adapter to a Schroeder-style air chuck

The standard hollow tube extenders are useful if your innertube valve is long enough to poke out of the rim but not long enough for your pump head to grip. Open the valve, break the seal, and screw on the hollow tube extension. Inflate. Screw off the extension. Close the valve.

[@blipco5]

Here's my hack for presta valves....I drill the hole out and put schrader tubes in as soon as I get the bike home. Done. 👍

[@JoeyMesa]

I guess if that's what you understand, then that's what you gotta do..

[@blipco5]

Joey Mesa - I don't have a need for the presta and from what I've seen it's much more convenient to air up at a gas station not having one. Plus, depending on the type of pump you carry on your bike, you can snap the presta.

[@kgilliagorilla2761]

Cold blooded. Ha

K.G. Thornburg - I don't mess around. I see a presta, I take it out. 💥💪😁

[@JoeyMesa]

@@blipco5 Seriously, you use the gas station to inflate your bike? Get a pump man! Generally, I use a Co2 dispenser to inflate my Presta valves if I'm out on the trail/road and get a flat. Unless you've got some kind of whack ginormous fingers, Presta valves don't just "snap". Use your brain, it's in there somewhere!

Estupenda explicación sobre las válvulas, pero no acabo de entender que vamos todos hacia unificar por ejemplo a USB C y, en cambio, volvemos a una válvula del siglo anterior, salvo por peculiaridades de una llanta de carretera donde no hay otra opción. Hablamos de Schrader (1.500 millones de vehículos) 1 mm de diferencia, no es objeto de rotura de llanta, la practicidad universal, no lleva tuerca, aguantan presiones altísimas como en los tractores, tráiler, motos de enduro etc., comprobar la presión es mucho más práctico, se pueden tubelizar, desmontaje del obús súper práctico, inflado menos arriesgado al inflar con mancha en la montaña al no doblar, me cuesta muchísimo entender ir hacia atrás. De todas formas felicitaciones por el video, sigo mucho tus consejos, eres un gran comentador.

Amazing video, the best I found on presta valves. Great job.

[@JoeyMesa]

Thank you! I really appreciate your feedback and kind words!

[@alexjboros9544]

I want to use Stan's sealant inside my presta tube but I'm a little concerned about the possibility of the sealant leaking out of the presta valve and getting into my pump, or getting into my digital pressure gauge, such as when inflating the tire or when checking the tire pressure. Is this a real issue or just an unfounded fear on my part? I noticed in one section of your video, when you unscrewed the presta valve, so as to then inflate the tube, some sealant came out when you manually depressed the valve core part (you did this before you put the pump head onto the valve). Looks like my fear might not be unfounded. And ideas or suggestions? Thanks

[@jiw71]

I have never had a problem with any of the issues you described.

[@JoeyMesa]

Line the valve them at the 3:00 or 9:00 position when inflating. The tubeless sealant can clog valves if you get a bunch stuck in the valve, but it's not as bad as Schrader valves or using slime sealant. Worst case, if it gets clogged, just remove the valve and clean it or replace it.

[@mountainjustice]

I have had multiple cases of a pinhole at the base of the presta valve. One bike shop mechanic told me don't tighten the nut all the way snug, because it pulls the tube up tight against the hole in the rim, and movement of the stem collar against the rim during pumping causes the failure. Any thoughts on that?

[@ALLANE1952]

Thanks for the excellent video...I bought a couple of Contis with Presta valves and the valves just don't appear to work straight out of the box..the centre of the valve core just appears to be loose and won't operate the valve locking mechanism. All I have ever done with prestas is just loosen them off and inflate the tyre and close the valve, no problem...but these just don't work...am I missing a trick? I've tried taking the core out but I can't see anything wrong with it other than it doesn't work. Thanks for your help.

[@Morpheus0000]

Never had an inner valve 'close itself' with an extender on, but thanks for the heads up.

[@JoeyMesa]

No worries! Yeah, working at a shop with lots of triathletes running tubulars with deep rims, I've seen it frequently. Trust me, it's no fun. The valve extender I was referring to is the type where you unscrew the valve and thread a tube over the stem where the valve cap threads on, leaving the valve and relying solely on air pressure to keep the valve sealed. The preferred extenders are the type where you remove the valve core, thread the extender into it's place, then thread the core on top of the extender. Those type work very well.

[@GeoffTV2]

Ooh! I never thought about unscrewing the valve and adding tyre sealant, that sounds like a great idea. One tip I would offer (only applies if you have a pump or adapter that screws onto the valve core - e.g. as shown at 8:00) before you install the inner tube, unscrew the valve core and thread lock that sucker in place. Otherwise you'll be out on the road, get a flat, fix it OK, pump up the tyre OK, but when you unscrew the pump it will unscrew the valve core instead. This happens because there is an internal 'O' ring seal on the pump connector (which you can see in the adapter shown at 8:00) which grips the valve core. Also can anyone explain why presta valves can be so resistant to letting air get pumped into the tyre? I find this feature of the valve really annoying, it requires me to unclip the connector and reattach it multiple times before I get airflow. Before you ask, yes I do tap the valve first to let some air out and unstick it.

[@pauleshelman5862]

Thank you so much for not letting me look as stupid as I was.

[@amiracal74]

Q. What if you buy a new removal Value core presta. Open the small part to put air in the inner tube attach the brass adapter pump up the tire. Then go to remove the adapter to tighten that small peice on the presta value and the whole value stem comes out letting all the air out. I know crazy glue can't be the answer it eats rubber.

[@matthewcrich5951]

@Melissa. You may need an adapter for your bicycle pump. Many pumps are designed for Schrader valves, not Prestas. And as shown in the video, the little “latch” on the pump head must be in the vertical position to allow air to pass, which for me, seemed counterintuitive at first.

[@richardjones2811]

Watch the video from 8 minutes onwards

[@JoeyMesa]

Hey Melissa, what type pump are you using? The tips I can offer are, unscrew the the top of the valve, give it a quick tap to break the seal, push pump head down, lock it in place and pump it to the desired pressure.

I'm not sure if I heard it right so I need you to help me with that, you said you squeeze the sealant through the valve into the tube to avoid punctures? If I heard it right, could you tell me why please? Thank you for the illustration of the valve I've never seen till I bought my bike couple of weeks ago. Your tips goes a long way.

[@JoeyMesa]

The sealant won't avoid punctures, it will seal the holes when you do get punctures. Does that make more sense?

[@holyduckr7700]

@@JoeyMesa do I squeeze the sealant in and use my fingers to move them to the punctured area? Is there any downside to this?

[@alexjboros9544]

@@holyduckr7700 You put the sealant into the tube before you get a puncture, not after. The sealant won't prevent the tube from being punctured, but it can seal the puncture almost instantly. Some punctures are too big for the sealant, such as a 2 inch gash on the sidewall, or a puncture from a long nail that stays in the tire, with the jagged, rusty nail half sticking out of the tire, kind of a thing. But most smaller punctures are almost instantly sealed when there's already sealant inside the tube before you ride. You can also search on KZbin under "Stan's sealant" and see instructional videos, or do similar searches

Since I only change the tube every five years or so. I reckon my Presto is not removable so I can’t put slime in it? So I need to buy a presto that I can remove and then I can put slime in it? Thanks

[@JoeyMesa]

Yeah, chances are if you have and older presta valve tube, the core is not removable, but it's not hard to check. I'd recommend a sealant like Stan's, Orange Seal or Bontrager TLR instead of Slime. From my experience, slime seals up punctures, but it also fouls up the valve and causes a slow leak in your valve core or making it difficult to inflate. The sealants designed for tubeless tires work much better in tubes than Slime.

Bike valves are such useful things ----- turn them into nice old fashioned lighters ; Schrader ones make great re- fillable ports for those "disposable" fountain pens! ; the internal threading even allows you to make them into paint lining tools---- for bikes of course!

But how do you remove the stem without a tool? I'm supposed to ride shortly and discovered no stem in back tire. Got an inner tube to use its stem and cannot get it out. So no ride for me.

[@robburke8867]

I can’t understand how my valve stem got pushed inside the while the tire was inflated? Ever seen this before and how in the world do I fix this problem?

[@JoeyMesa]

Sort of. Sometimes valves will get crooked under hard braking if riding a tire with very low tire pressure. The tire will rotate a little on the rim pulling the valve up and sideways. Other than that, it's hard to say without knowing what type setup you have. Presta or Schrader valve? It's possible the tube is overlapping itself at the point of the valve? I would probably start by letting the air out, resetting everything and make sure the tube is correctly installed, then reinflate.

[@robburke8867]

I wish I could let the air out. The tube must’ve spun on the rim. The stem is gone, and the tire is fully pumped up. Strange! Thanks for the reply though!

[@JoeyMesa]

@@robburke8867 So are you talking about the top part that unscrews? Sometimes those can break off and you can let the air out with a small Allen wrench by sticking it inside.

[@robburke8867]

It’s definitely a schrader value I’m sure the tube spun and the valve disappeared. I guess I’ll just pop the tube through the valve hole!

[@PatrickDuganOFFICIAL]

I HATE presta valves. Shraders are so much less fuss.

[@JoeyMesa]

Prest? Fuss?

[@toddseibert6401]

When did the presta valve come around and why? Why not just keep it universal or was someone trying to make people pay more money?

[@JoeyMesa]

The weakest point of a bicycle rim is where the valve hole is. Not a huge deal with fat rims, but for narrower rims, it is. You can deflate a Presta valve much quicker than a Schrader valve (not a factor for the home hobbyist mechanic, but it is for the production mechanic trying to squeeze 10 hours of work into an 8 hour workday). More options in valve stem lengths for Presta, and valve stem extenders for different rim depths and profiles. Sealant doesn't clog the valves as easily in Presta valves as it does with the spring in Schrader valves. Presta valves have been around since the mid 1930's. At the bike shop where I work, basic butyl rubber tubes are the same price for either Presta or Schrader tubes.

Im trying to understand. I am a 57 year old woman with a flat tire. So when I push the attachment, it must have to push in and lock, in a circle around the part that you push in to let air out. All I have is a air mattress pump, Ive been down a week. I have no hardware store. I need an attachment that presses down, around where the thing that lets out air, so I can inflate. There is, only, a Dollar General here. One gas station/fonvenience store. Antly ideas?

[@SuperWhiteMaori]

Yip when next intown go buy yaself a pump to suit the valve you have &keep it with your bike, coz thos presta valves are real delicate &can break easily so if the pump you have isnt correct to the application itll simply make destroying the valve while trying to use the wrong pump for theses valves , bicycle pumps are very cheap so I believe it good advice to suggest you purchase the correct pump apropriate to your cycles hardware. Goodluck.

[@the_hwyman]

The biggest mystery to me is the valve nut. I get that it's in aid in keeping the valve stem from sinking into the rim when you are attaching your pump, but what do you do with it after your tire is inflated? Take it off? Leave it on?

[@JoeyMesa]

Just make sure it's snugged down against the rim. If it's loose, it makes an annoying rattling noise. Thanks for the question!

[@namdarbolour9890]

If you believe it's a bad idea to snug it down, you can back it up all the way to the top and lock it back against the plastic valve cap. I'm not convinced that tightening it against the rim can rip the inner tube.

[@philcranston4479]

Thanks was scratching my head.

[@antoniopodesta8738]

I have an old fashioned pump for my presta valves. After I pumped my tyre up and when I unscrewed the pump, the lock nut was stuck in the pump and I could not get it out. Any advice would be appreciated.

[@JoeyMesa]

You'll probably have to disassemble the pump head if that's possible. Most all pump heads will come apart to replace/service the rubber bits that wear out. Once disassembled, you should have better access to unscrew the stuck Presta valve tip.

[@kgilliagorilla2761]

You are totally screwed. 🧐

[@EmilyWalker-h8q]

After I air up the tire, the presta core keeps coming out. How do I stop this from happening?

[@JoeyMesa]

The core needs to be tighter in the valve stem. If it’s coming loose this easily, it’s not tight enough.

[@Soprano0913]

Any tip for when the Presta valve core gets ripped out by the air pump and can't hold air anymore?

[@JoeyMesa]

If the valve core threads into the valve stem, you can simply just replace the valve core. You can tell if the core is removable if there are flat sections on the threaded part where the plastic cap threads on. If the core is not removable, you just have to replace the tube.

[@ussmillerco]

Presta is French made nonsense, no one needs. Over complicated and prone to leave you in the middle of nowhere, without any way to add air. Not to mention the poor souls in comments below stuck with these monstrosities. Sometimes we all fall for “different” as it’s actually better, when it’s not. Case in point, this video drones on and on about how terrible this design is. Don’t fall for it, the Schroeder valve is the king for a reason, no rattling , Mickey mousing it with electrical tape, a bunch of tools to lose, and other nonsense.

[@JoeyMesa]

It sounds like you saw that the valves were "different" and automatically decided they were terrible. Presta valves are actually less complicated and easier to inflate when you get a flat in the middle of nowhere and have to change a tube. Tire inflation technology has come a long way since the 70's. Not sure how you would use Schrader valves in a deep carbon wheel?

Why use tape instead of the retaining nut?

[@JoeyMesa]

Tubular tires won't have a threaded valve stem nor do the alloy valve extensions for deep clincher rims. I guess from a weight weenie perspective, tape is lighter as well, but for the most part, I think it's more of a style thing. Most stylish roadies wouldn't be caught dead with a retaining nut on their wheels, but in the grand scheme of things, a retaining nut would work fine if your valve stem is threaded. Thanks for the question!

To all you old riders n new there's supposed to be a washer with treds that supposed to go on the presta valve where he put tge tape and that noise is cancelled

[@PaTreck21]

Hello from philippines

[@PaTreck21]

Do you have email

[@junboo8730]

I’m new and have a doubt. Why you didn’t take out the tube and went tubeless?, does the tube with the sealant works better?.

[@JoeyMesa]

It really depends on the tire width, what the bike will be used for and your reasons for going tubeless. For mountain bikes, or any tire wider than 2" or 50mm, it's really a no brainer, because tubeless is the way to go. If you have a road bike with 28mm wide tires or less, and your primary reason to run tubeless is to avoid flat tires from punctures, I'm still not 100% on board with tubeless. There's not really an exact standard in the bike industry with different tire and rim manufacturers. Some rim/tire combinations are extremely difficult to mount and some are too loose and easy to burp or even come off the rim completely in a high-speed cornering situation. Other times, it's just a pain and you're constantly fighting a slow leak situation, not to mention how much of a hassle it can be to fix a flat on the side of the road or trail if you do happen to get a flat on a road tubeless tire. The bike in the video is my all-weather commuter bike. In a perfect world, I would probably have 3 wheelsets with different tire combinations, all set up tubeless. The problem is, currently I don't have extra wheelsets, nor the place to store extra wheelsets in my apartment. I probably swap the tires once or twice a month during the winter, which is not a good option dealing with the sealant mess and such. I don't really need super low air pressures either, so having tires with sealant in the tubes makes tire changes super easy with no mess, so in this particular situation, for me, a tube with sealant works better.

[@junboo8730]

Most of the newer ones are, but 5-10 years ago, almost none were.

[@danbooth612]

Man, if I only knew that before I spent a half a day trying to remove one. Thanks for the confirmation.

[@dylansimpson944]

What if the pin falls in, how do you get it back out?

[@JoeyMesa]

Before the valve core was removable, we used to force the little brass tip off, let it drop, but hold it in the tube while installing sealant and then work the pin back and reinstall the brass tip. I think that is the process you're thinking of? On most modern Presta valve tubes, the complete valve assembly threads out in one self-contained unit. Nothing to possibly fall into the tube, but easy to add sealant. If you have 2 wrench flats on your valve stem where the valve cap threads on, you have a removable core.

Sir thank u 4 this detailed info. Very useful info to help viewers become fundamentally sound

[@ariellevin3008]

Why not just use the value nut and tighten against the rim?

[@richardjones2811]

Yes a nut which has the same thread as the valve stem is commonly used to tighten the valve against the rim.

[@JoeyMesa]

If you're running a deeper carbon rim, you may have to use an extender which is not threaded. Also some folks don't like the nut directly against the rim.

[@ariellevin3008]

@@JoeyMesa Interesting about the nut. I've been riding for over 50 years and still snug down the nut. Are you suggesting it will damage a rim? I've used the nut on my Scram 80's, Profile Design 60's, and my off-brand 50's with no adverse. They seem to stop the chatter when I use them. Regardless, nice article.

Never inflate with valve down position of the week when you have anti puncture stuff

[@JoeyMesa]

Good advice!

[@lorilewis9832]

I hate presta valves. They just frustrate me to no end, maybe im retarded that way. What is the purpose of them anyway? Ill take a Schrader AND a kickstand anyday

[@JoeyMesa]

I guess I've just been exposed to both types of valves for so long, I'm indifferent. Presta valves are faster to get air in and let air out if you're swapping tires. On a narrower rim, from a strength standpoint, Presta valves are really the only options. There are more valve lengths available in Presta for a variety of rim depths. The part where the valve joins up to the tube is generally more durable on Presta valves than Schrader, at least from what I've experienced. All in all, it doesn't really matter. If you prefer Schrader valves, go with them. This video isn't about what type of valve is better, it's just about ways to better utilize the Presta valve. Anyway, thanks for your question and feedback!

[@AnthonySmith-h8n]

I lost my presta valve core in the tube

[@mylink.orb17]

Is that Woody Harrelson narrating this video? 😳

[@JoeyMesa]

It's a side hustle he helps me out with...

[@Mancmonarch99]

My whole tire went down and my floor pump isnt working ??

[@JoeyMesa]

You probably need a new inner tube if the tire lost air pressure. Check your pump on a known good tire to isolate the issue. The pump may be fine, but the tube just won't hold air.

[@Mancmonarch99]

Joey Mesa sorted it now mate was using wrong pump never had to deal with one of these valves before lol cheers anyway man

[@rterry2752]

OMG, you need to put a nut on the presta valve to keep it in place,NO TAPE NEEDED. Also when you push on the valve with a pump it will not be pushed into the rim !

[@JoeyMesa]

Many deep carbon rims require a valve extender, which is not threaded, so a presta nut is not an option. Same for tubular tires on carbon rims. The tape keeps the valve stem from clacking against the carbon fiber and keeps things quiet.

[@machiavellian7490]

Why? Mr Presta why did u invent this monstrosity!

[@richardjones2811]

Presta valves were common as there wasn't an alternative. There's Schraeder valves now so I don't know why they still insist on using presta valves.

[@JoeyMesa]

Maybe because they work better?

[@debbiebledsoe3206]

​@JoeyMesa better for what?

[@tigerbalm666]

I used and adapter and all the air went out...now a flat tire. POS valve system!

Dont be Schrader haters 💨

[@JoeyMesa]

I don't hate the Schrader valve, I'm just showing some of the benefits of the Presta valve. I could probably say "don't hate the Presta " much more often.

[@roby99]

no one in the whole wide world should need to listen to a 10 min video on those stupid valves companies develop to make money.

[@JoeyMesa]

Someone who is new to the Presta valve might find the information helpful. Presta valves probably cost less to produce since there are fewer moving parts, so I don't think it is about any company trying to make more money, but then again, I can tell you're an idiot because you edited your comment, but your punctuation is still awful.

I cant figure it out and I got hdhd and can't pay much attention for this long holy fuck

So basically go buy a new pump or go to the bike store I shouldn’t be commenting at this moment 😡. I’m pissed off🤦‍♂️😅

[@JoeyMesa]

If you own a bike with presta valves, and actually ride it, there’s no excuse for not owning a good pump as well. It’s the most commonly used tool for general maintenance…

If presta valves are your normal, just learn how to use them?!?!

[@MadDog-dn5st]

The presta valve is the absolute worst kind of valve and should be completely banned. It is virtually impossible to inflate regardless of the equipment used to inflate it. It can be inflated, however, if you feel like spending 10-12 hours trying.

[@JoeyMesa]

Hmmm...I've dealt with probably 100,000+ presta valves since the late 1970's, and I've had very little issue. I would have probably quit riding bikes if it took 10-12 hours to figure out though...

@@JoeyMesa no the presta valves are weak and poorly designed

[@JoeyMesa]

Oh well, too bad you feel that way. I've been dealing with them for 35+ years at my day job and never had any major issues with them. Definitely no more than Schrader valves, but you do you.

[@LumieX]

@@JoeyMesa So, the very 1st time I went to pump my new bikes tires, the valve broke off. I paid someone like 80$ to fix it and the same exact thing just happened. There's no way I'm paying that amount again and I feel like I got ripped off the 1st time even though it was a friend of my dads. Is it difficult to replace? Apparently the entire tire has to be taken apart and a new tube put in?

[@ussmillerco]

Joey, let me get this straight, the original poster says there terrible and they break, you blame him as if he doesn’t know how to inflate a tire, and you do all of this, after spending 10 minutes, talking about all the pitfalls of the design, even at one point recommending electrical tape, not to mention the countless horror stories of almost every commenter of your video, having a whole range of problems. ITS A TIRE VALVE! Spending anytime explaining the pitfalls of a tire valve bears out what the original poster is claiming. Just because they are on expensive bicycles doesn’t make them more worth a damn. The irony of it all. Great video by the way.
