Just been explaining that to someone. There are a few silly comments here but the need to push the attachment deep down onto the valve further than you think, is not often clear in instructions (if supplied)
Thanks a million! I was like is my valve messed up or is it my pump. Why do they make it so complicated but who knew you had loosen the nut on the valve igghh
Thanks man! It was even more difficult in my case, since my aero road bike doesn't just have a presta valve, it has an extender on it, and I just couldn't figure out you have to unscrew it first. Also do I need to screw the small nut on the valve itself back after inflating, or am I fine just putting a cap on the extender and keep riding? Thanks ❤
There is a strong case for ending use of Presta valves. They were needed when race tyres were 23mm or even 19 mm and pressures were 120 to 160 psi (even higher on track bikes). Today, professional road race bikes use much wider tyres (28 mm, 30 mm, even 32 mm) and pressures are down to a range from 65 to 90 psi with tubeless tyres filled with sealant goo (which doesn't work at high pressure anyway). However, lots of people still have old narrow tyre road race type bikes with caliper brakes (like me and my 2007 Cannondale SystemSix), so they need to hit higher pressures, so they need Presta valves. Back in the day, I was running Vittoria Diamante Pro tyres at 160 psi - they road smooth on rough poor quality tarmac but, of course, lasted just 300 miles and I couldn't afford to replace so I got cheaper tyres that just wanted 110 psi - now even that seems very high pressure
Hey Antonio, I just got my e-bike with a presta valve and I wanted to pump the tyre, when I opened the dust cap, all air came out immediately is that normal?
Most pumps have options to work with Shrader or Presta valves. You might get a Presta valve only pump but I don't think I've seen them. Usually separate attachment holes for Shrader or Presta. Sometimes you have to change the rubber ring in the locking attachment. Track pumps usually have a rubber ring (that can wear out and good brands can replace them) with a single locking lever. Hand pumps usually come with a screw thread to screw onto the valve - make sure there's a pressure release button or you won't be able to get the hose off the valve without losing pressure!
To get the hose onto the valve, not so much hard as firm - I think there is a difference in what those two words mean in this case. You'll know when it sort of slides on as far as it will go. If using a hand pump to get to something like 120 psi, yes, you do have to push hard! - and do it without sideways pressure on the valve that will bend it and make it useless - which can mean you bash your fingers on the spokes - painful!
Same as has been the case for over 100 years and how you've been doing it all your cycling life. A) Read the pressure range off the tyre wall (sometimes in small black print on a black background so takes a bit of effort find it); B) Make sure you know what pressure unit you're going to work with (usually bar or psi) and go for the middle of the range; 1) see the reading on the pressure guage on the pump until you reach the figure you want; 2) use a separate tyre pressure guage; 3) use your thump to press on the tyre - if there is almost no give to a hard press, you've probably got enough air;
I wish you’d put a link to the Preston bike pump you have. FYI, I tried to use an adapter to the US standard and it’s not working. So I guess you need to buy a particular bike pump for presta, how annoying. I have a regular air compressor for standard, but I can’t find an adapter that will work with the air compressor for Presta.
My mini bike pump needs to rotate to lock on onto the presta tip, but once I try rotation the bike pump off, it also rotates the presta tip off and I lose all my air? What the fuck am I doing wrong
Early Presta hand pumps all did that. Then manufactures introduced pressure relief buttons so the pressure in the pump got released and allowed you to unscrew the hose from valve to pump. A few decades ago, I remember getting furious at pressure loss after hard work pumping tyre after fixing a puncture
They are unnecessary now - except for narrow rim narrow tyre road race bikes and cheap lookalikes. They are for getting tyres to 100, even 160, even 240 psi. Until quite recently, standard road race tyres were just 23 mm wide, some even down to 19 mm (3/4") for smooth road surfaces or track racing. Today, professionals know that wider (high quality expensive) tyres up to 32 mm (1 1/4") at much lower pressures (60 to 80 psi) are almost always faster than narrow tyres due to more compression letting tyre work with micro-bumps in the road instead of bouncing up and down on them like a solid tyre would. And, counter-intuitively, modern wider tyres with wide rims can be much more aerodynamically efficient than narrow wheels and tyres. It took quite a lot of effort to change the minds of professional road bike racers from high pressure narrow tyres are bad: they bounce on the road, they are aerodynamically bad, they are more liable to puncture, they slip on wet greasy roads and crash more due to less contact with the road
Why don't the manufacturers just use regular valves, instead of this fragile, weird contraption? It shoulf be like the Beta vs VHS...the VHS won in the end and thus everything was compatible overnight. In this case the regular, tested and proven valve shoud be the clear winner so there is no need to fuck around with this useless, overcomplicated POS.
Not a modification. Presta valves were essential for high pressure tyres on narrow rims up to just about 5 years ago when professionals started to realise lower pressures on fatter tyres was better for many reasons. Nice to see someone write 'should've' as short for 'should have' instead of 'should of'
How about an internet literacy course where they teach old bastards how not to put their full name in their RUclips account, making them very easy to find IRL?
Actually... schools in US and UK finding more and more children arriving at first day in school who can't clean themselves. Not talking learning difficulties children but parents and carers never showed them how. Some of us have been fixing punctures from 1960s but when we first got a race bike with narrow tyres that run at high pressures in 1970s, we had to use Presta valves and figure out how to pump them up. I remember my old pump exploding in my hands as the pressure was too high for the body of the pump and the hose got extremely hot
Phew. I had no clue. Thanks! Now I can ride 😊
Happy to help!
This ain’t no 10 min video but exactly what I was looking for thanks man
Oh my God! I’ve struggled for so many years and now I’m all set with the same pump and no adapter at all! Thank you!💔❤️🔥
Much better than the other videos on this subject.
Dude opened a wormhole in the universe with that pump 😳
This is the only video I could find that mentioned how to switch the valve on the pump thank you for including that
Protect this man at all costs. 🙌
Just what I needed. Thanks for posting this.
I was also setting up my propella e-bike with this same kind of pump, this video was super helpful!
Ayyyeee 🤠🤘🏼
That was easy
Nice wheel color!
Thanks for this mate! You saved me a trip to the cycle repair store! 😅
Thank you for showing that you can actually push it the valve in properly for a snug fit, so that the air ain’t coming back out when your pumping

You bought an aero road bike and didn't know how to pump up the tyres! That I do not understand
Why do we need to overcomplicate everything that worked perfectly fine lol
Just like dildos when men weren’t good enough…
I know...fucking hell
I know right! If it ain't broken the end
Send emails to the manufacturers, cuss those idiots out!!!
I totally fuckin agree.
Do u any adapters imma buy a bike with them bike is new these need to be weeded out back to the norm lol 😂 love your channel
Appreciate this a lot. My pump had no instructions, just that it could do it lol
There is no reason that they couldnt just stick with the normal tire pumping system.

Great short video. Thanks!
You saved my life bro like totally
😂😂🤠
This video helped me so much man! Thanks!
Thanks, Just what I needed!
So my regular pump won’t work for this ?
Good explanation! Thanks for the video!
Very helpful
Saved the day. Thank you.
Thanks a lot!!! Very useful😊
Glad it was helpful!
Bought a bike of fb market place. This valve makes no sense. Thanks. Good vid
thank you so much, you just saved me
Thanks man I would’ve never figured that out
Thank you very much
Thank you
No problem!
Hey Antonio, I just got my e-bike with a presta valve and I wanted to pump the tyre, when I opened the dust cap, all air came out immediately is that normal?
No, maybe the screw was unthreaded
Thanks much appreciated
Life saver ong
Dos my skinny bike tyre have a special pump, or is it any pump 🤔

Bro thank you
Looks like you have to push pretty hard, is that right?
To get the hose onto the valve, not so much hard as firm - I think there is a difference in what those two words mean in this case. You'll know when it sort of slides on as far as it will go. If using a hand pump to get to something like 120 psi, yes, you do have to push hard! - and do it without sideways pressure on the valve that will bend it and make it useless - which can mean you bash your fingers on the spokes - painful!
how do we know if the tire already has enough air?
By riding the bike???
Same as has been the case for over 100 years and how you've been doing it all your cycling life. A) Read the pressure range off the tyre wall (sometimes in small black print on a black background so takes a bit of effort find it); B) Make sure you know what pressure unit you're going to work with (usually bar or psi) and go for the middle of the range; 1) see the reading on the pressure guage on the pump until you reach the figure you want; 2) use a separate tyre pressure guage; 3) use your thump to press on the tyre - if there is almost no give to a hard press, you've probably got enough air;
@@cuebj Cycling life? Huh. Interesting..What about? If I dont have a cycling life before?
Great 👍🏻
I love you
I cant believe how much I went threw before this video. I feel like a pro now. Thank you
My first time pumping up my bike tire, the moment I removed my pump, the little presta tip nozzle came with the pump and I lost all my air
I didn't know Dave Lombardo from Slayer made bicycle videos!
Hahaa “this feels like good”. Always so nonchalant

Bruh why would this company make a value like this bout to return these
I hate presta valves. Going to attempt to never buy a bike with one ever again lol
Stupid presta valve 😂
Why change it was good the way they always been 😢 wtf

Really? Yikes...next, how to wipe yourself after using the toilet...
Lol hey man, school never taught me this haha
shut up
