How To Pump A Bike Tyre

[@oreosaysb00]

I don't understand why there's so much hate. When I was new to road biking, I didn't know how presta valves worked.

[@pauldenino2560]

I'm here because my tire just exploded while biking.

[@luismariano8701]

i was upset how my tyre stayed flat because i domt know how and cant ride when i was new

[@gaborvaradi7946]

I just got to know them now! :D

[@Grendal_irl]

[@rachelmiller3072]

Exactly why I'm here. And now I know.

[@OliverCharles]

Disappointed with the haters. I have a new friend who's just getting in to cycling and she's afraid of pumping her tyres because she's never done it before. You always have to learn, no matter how trivial something might be to you now. To the haters: stfu and stop ruining this sport.

[@Erginartesia]

Oliver Charles negative comments from people about teaching new people the basics is the mindset of a clique. GCN has a teacher’s values. For cliques, the more you learn, the less you realize how little you know. Teachers remind us that it should be the opposite.

[@Songbirdstress]

Just got front and back punctures on my new MB. Am finding really difficult to pump them back up. This is invaluable. It seems easy but if you don't know....

[@ItAllFadestoBlack]

Thank you, I don’t have anyone to teach me but I love to go on my bike. I felt really stupid and frustrated that I couldn’t get it but this comment is right! Everyone should get the opportunity to learn

[@asdasd01]

Lol

[@juliette8463]

I was ready to give up nd buy a new bike bc I couldn't pump up my tyre? Im new to this also.

[@mykiee5638]

Damn this is the question that I'm embarassed as hell to ask my friends

[@CarlosRodriguez-sl3qy]

Haven't been able to use my bike for two years bc of this. THAT is embarrasing.

No thank you sir?

[@bernadettephillips1437]

This is so helpful, thank you! Now I know why my tyre wouldn’t inflate properly. Clear instructions with good camera shots - this newbie cyclist is very grateful to you for not making her feel like a total idiot.

[@channelpolitica1364]

[@EverythingisFire]

Good video despite the elite mechanics in the comment section. Someone going from a beach cruiser to a road bike would appreciate knowing how a presta valve works.

[@uniformcharlie6628]

The first time I switched from schrader to presta I struggled a bit. Viewers should keep in mind that the content at GCN is for everyone, including individuals who have no experience in cycling, let alone basic maintenance. Moreover, GCN works very hard and very honestly to produce these videos, it's their day job. So if you can't appreciate it, hold your peace.

[@ZoeMillar]

This was super helpful I don't do much cycling and was struggling for a bit wondering why my tyres wouldn't pump and it was that little tricky valve i had never seen before!

[@gcn]

Glad we could help :)

[@TheWaxChainFanClub]

It should be remembered that somebody somewhere has just bought a new road bike, or got one on a cycle to work scheme, maybe never having seen a presta valve before. Everybody needs shown the first time, for me the first few times, criticism of this instruction says more about the author than the content. Thanks Si.

[@criteriumgoat6525]

I've had the same experiences with my first Road Bike, this video ain't half bad, It helped explain why I'm having a hard time pumping air even if the pump is properly fitted and secured on the valve.

[@shanerose9827]

That would be me. I just went to put air in my tires and I took the cap off and was wtf is this

[@Damakke]

i remember the first time i tried to pump up the tyres of my roadbike. i have never seen these presto valves before. i didn't unscrew the valve and started pumping :D it didn't work and i thought the pump was broken. i was so pissed off...i couldn't believe it. the fucking air didn't get into the shitty tyre...i went upstairs to my pc and googled how it works. damn...i was pissed off

[@guest_informant]

Good post, and the kind of newbie thing we've all done. Btw I think it's Presta not presto - though all the geniuses who hated on the video knew that already.

[@07madiaga1966julio]

This video is the reason why, GCN, is the best damn, cycling show ever. It is the cycling show that appeals to all cyclist, from beginners, which is the most important, and to professional elites. From the novice to the snob. A truly democratic show. Imagine doing this task everyday, and not being boring or dull. I have been riding for 40 years, and yet, I still watched this video on how to inflate a bicycle tire. WHY?? Because the way it was explained and presented by Simon and GCN, is a model of how things need to be explain,.Again, KUDOS to GCN!!

[@gcn]

Appreciated. You understand why we did it!

[@Erginartesia]

Every time I run into a new problem with my bike, I type out "GCN: How to..." and here come the correct answer given patiently, confidently, generously, and very helpfully. And, it's FREE! There is nothing on GCN to criticize from my point of view. Also, I enjoy the humor and self-deprecating attitudes. It's almost enough to get me to wear lycra. Almost. Thank you all, very much.

[@beeasy32]

Dude. Thank you so much. I haven't ridden my road bike in years and have to now bc my car stopped working. I was struggling with inflating my tires and your video gave me such euphoria to see my tires inflate after struggling with them for an hour. Huge help. Thank you SO much.

[@mbolton13]

This was SUPER helpful, many thanks!

[@helenarichard]

I was today years old when i realised that different pumps have totally different handles. Some pumps need to have the handle up when pushing them onto the valve. Other handles need to be down when you do that.

[@johnh5259]

One very important thing missing - when inflating the rear tire, work from the left side of the bike. I learned the hard way the first time I pulled the pump head off the valve and smacked the back of my hand into the cassette.

[@FlatSpinMan]

Simple topic but trickier than you'd think for newcomers. I had to Google just about everything when I got started, and that is what led me to this channel. It was the "5 minute bike wash" one that really sold me, despite it being extremely optimist timed.

[@kathleenpovey333]

Thank you for making this video. I just got my first road bike and it has a presta valve. I wasn't sure how to use it. This video was very helpful. I am learning so much from GCN videos. You folks do a great job!

[@GoonerBuller]

obviously people are gonna moan about this video but I think it's helpful. of course most of us can figure this out by ourselves but it's good to have a run down of the different valves for beginners. thanks GCN.

I have recently relocated from Australia (Schraeder valves) to Scotland (Presta). This has been most helpful. Thank you for your video.

[@ZaeroS182]

Thanks a lot! It really helped me, never saw a presta valve before, bought a pump and could not get air on my bike's tyres,. Then 1 minute into the video and I understood how to do it!! You guys are the best!

[@candecarro]

Hi, I'm 74, and have been riding since I was 5, off and on (no pun). In 1984 I bought a beautiful, skinny-tire, high end road bike and rode it for about 20 years, thousands of miles. Then since 2007 or so I was just riding occasionally, on vacation on any conch bike available. This week I bought a new Schwinn Cabo cruiser bike, online. It arrived today and I had to put it together and then "adjust" everything. Four hours later, I'm done. I had to release air from the feont tire to get it on, Then I was unable to get rhe air pumped in again. Whether it was just pausing and starting over or watching the video. It's now ready to go and I took it for a spin. Now to install my lights, mirror, bell and basket and I'll be done.

[@TraumaER]

*Wait a second! I just got a 2021 Trek ALR4 bike and have been pumping the tires without removing the small screw on the presto valve for months. I have already had 1 flat too. Just found out tonight that I was never putting any air in the tire the entire time. I'm pretty smart btw and have 2 Master's degrees.*

[@guest_informant]

I really like these basic _How To ..._ videos. I think they're really useful (and in different contexts even important). Well done to Si, for pointing out that we all needed to be told everything we know at least once. If all this is beneath you, then there's plenty of stimulation for intellectual giants elsewhere.

[@helenteague1734]

Still don't understand why modern valves have to be so fiddly and complicated. In the old days you just screwed the damn pump on and pumped. It worked.

[@Busybeeee]

I feel so ridiculous not knowing how to put air in my tires! This video makes it look so simple however I don't have this type of pump, I have a manual screw on type. The issue I am having is that everytime I unscrew it, all the air comes out! Any suggestions? The clip on attachments don't fit.

[@hutch430]

May I ask? Do you guys deflate your tires between rides? If so, why? I have been doing it ever since day one. Don't know if it's necessary?

[@gcn]

We don't tend to, no. Can't remember what the reasoning was behind doing that.

[@hutch430]

I remember now. Back in the day we raced or rode sewup tires. We would always deflate them for whatever reason I forget. I just kept the same practice for years. I have been told with the newer tires it is no longer necessary. BTW, I love your channel. Keep up the great work.

[@johnbouttell5827]

It's wise to deflate your tyres if you carry your bike in the back of a hatchback. It gets warm in there and your inner tubes will explode.

[@Diane_R]

A member of my bicycle club took their bike to work and stored it in the hot car during the day. When they got to the club ride in the evening after work, they often had a flat tire. After they started to deflate the tires while the bike was being stored in the hot car, the flat tire problem was solved.

[@gcn]

yep, I have had tubular track tyres explode whilst in the back of a hot car whilst driving along the motorway! as well as seeing them explode on a sunny day in the centre of an outdoor velodrome. Jon

[@djfazokh]

well since this has become the wall of shame. i aint going to hold back. bought a cycle 6 months from now and actually i having been pumping the cycle tire every week for half an hour, it was so and so i felt like it has become a good excersie . little did i know i never unscrew the vavle and my pumping air was in plain vain for 6 months until today got pissed and wonder why i am pumping so long and tire is not stiff as it should be until i youtubed it and it toke 20 seconds to refill the tire. lol hahahaha i am not even embrassed honestly its just unmatch funny story.

[@Naturalhighz]

You might have wanted to include that with latex inner tubes you will need to inflate more often than a normal inner tube as they do deflate quite a bit even within 24 hours.

[@ethansloss6854]

If you need to watch a video about how to inflate tyres, lets face it, you're not going to be using latex tubes.

I always fill the tires on my wife's bike, and I'm sure the last time she pumped the tires herself she had schrader valves, and would be intimidated by the presta. If nothing else, seeing this video makes me realize that there are some basic skills I should double check that she has. She has all the gear on her bike for typical problems, but that doesn't matter if know one is present that knows what to do. My as well make sure my 13 year old son can do these things as well.

(electronic shifting, more aerodynamic andlighter bikes that give you a worse workout) you can't have it both ways. If you are explaining the Tour, grams of weight saving, power meters and ways to improve timed by watts and miliseconds...YOU CAN'T HAVE A..."HOW TO INFLATE YOUR TIRE/TYRE" video.

Seems to me that, while lots of people seems to be giving smart arse comments on how obvious it is to pump up tyres, those same people haven't figure out how to not click on a video if they think they don't want to or don't need to watch it. Surprisingly, no one has made this video yet.

[@deborahelaine9985]

That video is Much Needed. I was going to suggest that you label your videos Basic, Moderate and Advanced. Plenty of people who are at beginner levels need some moderately advanced information too. Maybe code the videos with combinations of Beginner - 1, Moderate - 2 and /or Advanced 3. If any of the advanced people can't tolerate a moderate level video or combination level rated, they don't deserve to see the information. The people complaining about this video are not even decent people. I feel sorry for anyone who has to live with them or work with them. I'm sure there are many advanced cyclists who are not like that. Their comments are noticeably missing from the comments under this video except when they're trying to help someone. These are the people who are truly loved by friends, family and coworkers, and thought of with respect and fondness.

[@davetbrunner]

Perhaps a deliberate attempt to find the best comment of the week for the next GCN show 😜 Kidding aside, many beginner cyclists can learn a thing or two from these no brainer videos. Part of the enjoyment of working at a bike shop is teaching new riders the basics ;)

[@brianmoore1164]

How about a GCN does science on how much pressure is lost during an efficient pump removal because I know that not all the air you hear is from the pump hose.

[@ethansloss6854]

It's less than 1 PSI

[@exe16]

Depends on how much pressure is there to begin with. On MBT (pressures up to 60psi) it's barely noticeable, but on road bikes (110psi+) it may be up to 5psi if your pump is of the screw-type, from my experience.

[@ethansloss6854]

I was baffled when I saw this hype of valve but I managed hah

[@marvess]

1. Yes, it's entirely possible to bend the little stem of a Presta inner valve. Some brands/types are more prone to this than others.You can mostly prevent it by not screwing out the lock nut completely but leaving a bit of the stem at the end.... 2. When screwing in the lock nut, make sure not to overtighten as this may damage the rubber inner valve seal which will result in either a sort of a slow puncture or an instant catastrophic flat... 3. While we're on the subject, you are able to screw out/remove the inner valve construction (rubber inner seal, stem and lock nut + housing) from a Presta. For instance for inspection of the seal (now we all do that regularly, don't we !?). When re-installing, you should ideally tighten it with a special valve key....a rather inconspicuously looking, usually plastic, hard to find thingy that snugly fits over the inner valve with the sole purpose of tightening it without screwing it up entirely.....finger tightening will not work to full satisfaction, pliers will screw up your Presta and your day...Removing the dust cap will overtime result in slowly but surely loosening your inner valve, resulting in yet another, inexplicable slow puncture and screwed up ride....just a hint of a very mild Loctite on the inner valve thread (careful not to drown the stem or seal!) will save your day.

I learnt a lot from the video. I've owned many bikes, but none had a presta valve because they were just mountain or commuter bikes.

better be well informed than just wing it!

[@BestEndDB]

Bro im such a noob at this shit but i never ride a bike so this was very helpful gonna refill my dads tire for him

[@gcn]

Glad we could help!

[@Prettorian]

Stop hating! People around the world are born every second so it means that every second you get a fresh bike newbie who can appreciate these kind of videos! I know quite a lot about bikes and I still look forward to these. GCN crew rocks!

What is the gray on the valve stem? Is that something added on to prevent the rattling you typically hear over every damn bump in the road? I've been trying to find a way to deal with that.

[@rantingwrench]

I always stick a little piece of electrical tape over them. Cut a length, make a little hole in the middle, stick the valve through then smooth onto each side of the rim (but not your brake tracks!). Only ever had this problem with deep carbon rims though.

[@EnigmaticAnomaly]

Now that's a decent idea. I'm going to try that this afternoon. Thanks.

I just embarrassed myself infront of my gas station since i changed from a mountain to a fixie

[@Claire_Loves_Music]

Aww that's ok. We all have embarrassing moments. Just yesterday in fact I embarrassed myself because I accidentally fell off my bike in front of the gas station.

[@victoriaspringer212]

I had not done it in so long, wasn't working; needed a refresher course. Thanks!

I notice you guys are running 28mm tires on your zipp wheels,,,can you compare these with 25mm tires in another video or just respond to my comment please? Thanks!
