I ride all the time and have had a ton of flats. I’d add one caveat to this excellent video. DON’T carry a patched tube as your spare. When I get home, I promptly repair the replaced tube from my ride and swap it out with the NEW tube I used while on the road. I put the non punctured tube back in my carry bag. I was once stranded in the middle of nowhere because the tube patch failed and that’s not the place to discover this. Just my thoughts based on actual real life adventures.

idk where I would be cycling wise without these videos. thanks for being there parktool. my dad wasn't around much and here I am in adult hood trying to figure shit out on my own.

I've returned several times to this video - it's been of much aid in dispiriting moments. Thank you, and my compliments to your magnificent mustache.

Thank you, I was struggling to get the clear film off the patch, didn’t realise it’s supposed to stay on.

Thank you for a great more video. I had a suggestion about patching, i normally do all steps as you mentioned above but an step further, that is ; before applying the patch on the inner tube i inflate the tube to a diameter equal to the bore diameter of tire itself, then apply the patch, push the patch by fingers and wait for about one minute، then deflate the tube and insert it as you mentioned. This minimizes the stretching of the patch while inflating the tube with high psi and prevent it from detaching and lengthens patch stability. 👍

This channel has helped me so much as I started cycling

Thank you for great video! Another small tip is always placing tube valve somewhere under the middle of the tire label when initially installing the tube. When you find a puncture and align punctured tube valve to the middle of tire label then you know where on the tire or rim a place possible puncture cause is to inspect it more thoroughly.

I noticed that I had a puncture in the front tyre of my Moulton on the way back from the supermarket. Prepared as always I whipped out my brand new, unused Park Tool puncture repair kit and prepared the inner tube for a patch. Opening the tube of rubber adhesive compound I found the tube to be sealed, but completely empty, In the manufacturing process something had obviously gone wrong. Fortunately on this occasion I had a spare inner tube, which saved the day. I decided to go further up the food chain of puncture repair kits and bought the highly recommended Rema TT02 kit. This is my second one and Rema are at the top of their game as they fill their adhesive compound tubes with more than air! You actually get the adhesive!

Never was able to fix a flat with a pre glued patch. I always used the old fashioned ones .The rest is easy. I,m Dutch so I fixed a lot.

Great tips! Great video: well shot, well edited, well directed, very well presented. Also no waffle or padding in the narrative, just straight to the point. Thank you very much. Though I'm a very experienced biker, I still picked up some fantastic useful tips like - the 'crosshairs' marking the hole, and not just the 'ring' which I'd been doing which became obscured by the glue - the leaving of the plastic sheath on the outside of the patch to reduce friction on the patch (I always worried that it would 'pull' the patch off, how wrong was I!) - not inflating the tube to usual pressure outside the tyre. I long suspected this might be the case where the bond is weakened due to no support from the tyre, but wasn't sure. Thank you too for confirming that for me. Overall, excellent, excellent video. Why can't all '"How to" videos be as overall well-done as this??!!

I had to learn this when I was ten. You learn to repair stuff when your poor.

This guy is the Hickock45 of the bicycle world.

Good detailed info that many cyclists don't know. Thanks Calvin!

These videos are so good. Simple, straightforward, great production. What a KZfaq instructional video should be!

Always watch these even if it's a topic I think I know. There is always at least a tiny nugget of new wisdom in them.

My dad was sleeping and I was sad so I watched this video and it worked ❤😊

If it wasn't for your video, I'd probably have not looked for the thorn still embedded within the tyre and have gotten another picture. Thanks ever so much for posting this video!

Great video. Clear informative instructions, and really great close up shots the whole way through. Also really appreciate the split screen parts showing proper and improper bonding, and the different sorts of parts you may end up working with on your particular bike. Thanks!

First time ever having to patch an inner tube and this was great, super easy to understand

I'm patching my bike’s tube in this exact moment and this video was the best tutorial one. Thank you!

If there's one thing I certainly learned from this video, it's that the spikey bit on the cap of tubes is to pierce the tube's seal

I was doing it wrong this whole time, I put the patch right after I put the glue. Thank you 🙏

My husband bought a CCM repair kit. It has been awhile since he has had to buy one, so of course the black patch outlined in orange was new to him. The kit came with absolutely no instructions. Good thing we found your Video which showed which part of the patch should be facing upward. He had it the opposite way. Perhaps CCM didn't include instructions because they just assume that everyone has access to the Internet to look for instructions. My husband commented that if someone got a tire puncture while biking on a trail in the middle of the woods then instructions would come in handy! Mind you, CCM might suggest you use your smart phone to find a video such as yours, but, we are the lonely few that does not have or use a smart phone. Thanks for letting my vent! I plan to write to CCM to ask why instructions weren't included in this repair kit.

I had a blow out when I put a new inner tube in my front wheel. I didn't notice the tyre was not seated properly when I put it back on the wheel rim. I continued to inflate the tyre and then......BANG!!!!!!!!!!! Very very very loudly bang because the inner tube had burst.....blown out because it was trapped between tyre and rim and was outside the tyre. I learnt a lesson......always check tyre is seat properly when inflating the tyre.

Nice video!! Didn't know the trick of spreading the grue with the foil of the patch, very clever! Most of my punctures are the "snake bite" type, some times they are so big even the biggest patches don't hold enough the high pressure the road tire needs and I have to discard the tube wasting a patch in the process...

Great video! Fixed my first flat tire without any major hiccups.

I prefer to use the stick on patches. Just peel off from the backing and apply to the tube. No messing around with glue and waiting for it to go off. Works very well.

I used to buy a brand new tube after every puncture... $20 surely adds up overtime.

Thank you!!! A great video. I've been riding for many years but it doesn't hurt to have a refresher course every now and then. :-)

This video is so well presented that I have to comment where an improvement can be made: at 4:15 use water as the solvent nothing else. Rubber is hydrophobic and those loose rubber bits just float away as if they are repelled by the water. And rubber dries instantly. No need for anything more volatile. Thank you for putting so much information so concisely! Brilliant!

I never knew to wait until the fluid is dry, before applying the patch

Sending this to my brother the flat king

Park tool is SO COOL! I just bought a side mount park stand! LOVE IT

Excellent video! Thank you. Just to add to that, where you find the hole on your tube gives you a huge clue as to the cause of the puncture. If the hole is on the inner circumference of the tube as mine is today then it's likely due to an inadequate rim strip. If it's on the outer circumference then it is likely from a foreign object such as glass, sharp stone or splinter.

Great video. I had a discussion with a friend today. He said the patch should be glued without film removed. I ended up removing films from both sides and put it orange side up). Looks like we both were wrong.

Great concise video. I saw a guy once when he got off his bike spin each tire and rub his hand over it to knock off debris. I did this and it cut down on the flats enormously. I also do it when riding.

Calvin, I ride on my patch tubes and carry only new tubes for road repairs. I give each tubes a three patch and out rule. :D

*I didn't have any patches on hand and had a flat this evening so I cut a patch out of a spare inner tube and used krazy glue as adhesive. Put everything back together and inflated the tire to 100 PSI. 4 hours later and it's still holding so we'll see.*

Thanks! I already fixed a flat on my granddaughter's bike and kind of learned some of these things the hard way, lol. But now I feel better prepared for future issues.

This is the greatest video I have ever watched

I was just trying to fix my bike a while ago and I couldn't do it. I have a similar packet to the repair patch you just showed. but I had no idea how to use it I tried and tried and failed but now I know the right way to do it I'll go try it right now.

Thanks! Up/down! Right in the middle at least here! Thanks for video as a referance! Nothing worse than a kit having no instructioms and needing a quick back up to get striaght to the job! Awesome!

Thank you so much for this. I'm learning how to repair my electric bike and all it's issue on my own thru KZfaq videos. It's getting to costly to take it to the shop each time so I gotta figure this stuff out. Plus I really like to be able to fix my own stuff. Seeing what causes the types of holes was really helpful too.

Like the father who never wanted to teach me. Thanks dude!

Wow I did not come here expecting to learn something. I never let the rubber cement dry a little bit before putting on the patch.

Novice bicycle rider here. Thank you for the tips to help me patch a pin hole in my front tire

I replaced many tubes in my life, this time idk why I thought I’d check a video about a how to while the glue was drying. And one thing I almost forgot this time was to check the tire for what caused the pin hole. Sure enough I went back to my tire and there was a tiny thorn coming through, saved my day lol. Thank you.

On a scale of 1 to 10 where 10 is the best, I'd give this fellow and his presentation a 15. Everything about this video is over the top excellent. Thanks 👍

Santa Barbara locals saying thanks had electric bike with off-size tube watched it in the Kitchen with other folks busy making dinner patched the tire had dinner and rode to Hendrys Beach for a test all went well thanks again will get a new tube later in the week but this kept us in buis cheers keep up the good work

This video is so thorough and excellently produced. Extremely helpful. Thanks so much!

Holy Moly, you guys made a great video. Lots of tips and a good reminder for us oldsters who haven't done this since childhood. Much appreciated.

After applying the glue wait three or four or five minutes let it dry then put the patch on I've learned that the hard way excellent video

Great video , haven’t used a bike in a while , was unaware of the proper way to attach this new patches . Thanks for uploading

this is a really good video. what Calvin doesn't address: -there are places on a tube that are difficult to get a good seal. these include the seams, and then those seam-like tire markings and machine marks. try the best you can to get the patch solidly on the hole. -getting the edges of the 2-part patches (where you put the cement on first) to seal properly is important, and sometimes tricky. Final thought: I'm playing around with RTV -blue silicone gasket maker as a way to seal the edges of leaky tire patches. I THINK it just may work. Currently, pre-massive-inflation-that's-coming, the stuff is about $4 per tube, and it just takes a small amount.

Very clear, informative video with no waffle. Thank you!

After going through perhaps my fourth inner tube, I think I'll start using patches. Thankfully, I still have my old ones. I'll examine the size of the holes and "recycle" them! Suddenly I'll own 4 spare inner tubes.

Such a fitting video for youTUBE! 😅

Nice video. With this information I can better manage my inner tubes and keep them fit for the road. Thanks

You guys are amazing blowing up a new tube to show us the example and also filming 📹 is perfect the background too love ur channel

Thank you 😊 dude your the best I will leave my first born on your door step

i'm learning this to fix nikes new vapormax bubble.

i have had several Patches fail to seal, after this video i think i have discovered my mistakes, but i do have problem finding a good patch Kit !

Another hot tip… When inspecting the inside tire surface for the foreign object, wear bike gloves to avoid getting cut by something sharp!

I've never known about those TB-2 tire boots, very cool! In the past I've used a slice of a NYC metrocard (like a much thinner, flexible credit card) works well to hold a blown-out tire in place. A suggestion for those in other cities who might have similar cards in their wallets/purses.

I always thought u where supposed to put the glue on the patch a just put it on the tube this video actually helped

Thorne Resistant tubes are the answer and sure some complain about the weight but its a bicycle and its all about fun and exercise so what a little extra weight.

Thank you for a so detailed video. You took the time to present the good and bad scenarios within the process !!!!!!!

Park Tool videos are the best. I never knew I could learn something about repairing punctures, thanks!

Thanks for the reminder about checking the tire for objects. I had a small tack stuck in the tire. If I didn't remove it the tube would have been immediately punctured again.

Great video! That railway nail was overkill!

Just want to thank this video. If I didn’t watch it I would have patched my tube and made another hole from a thorn stuck in the tire

yaaayyyythank you sooo much just changed my first tire!

I just fixed my tires thanks to your video! Thank you very much! :))

I never knew to not test the patched tube until it's inside the tire.

your videos are brilliant

Superb video. In my case with the vulcanizing patch I remove the film backing after pressing the tyre for an hour in the vice. Then I sprinkle it with French chalk which is known in America as 'tire talc'. The removal of the backing film requires 'technique', and I was stopped in my tracks to see that not only did CJ not remove it, but he gave a reason with his customary nonchalant authority. If anyone else had left the backing film in place, I would have remonstrated, but who in the world can go up against Park Tool? By the way I have never seen a tyre repaired on such a spotless bench in such bright light!

Removing rear wheel is a pain in the ass for me,so I learned how to patch the tube without removing the wheel.

park tool is my channel of infos about my Bike Maintenance

When I grow up I want to be just like Calvin.

Your videos are simply amazing!

Very clear and straightforward; thank you!

This video was really helpful. I can't wait for the next upload.

I bought your patch kit on Amazon becuase of this video

This was a useful video. The instruction was detailed and straightforward.

Thank you for this video, helped me to prevent myself from buying a new tube

I use a white or other light colored crayon to mark punchers in the tube.

Thanks I bought a park tool patch kit wasn’t sure how to use it I do now by watching your video 😊👍

Best guy for bikes better thank going to bike repair guys

There are tonnes of thornes in the high desert. I am intrigued about using discarded venetian blinds as thorn guards. I think it would work well

Wait what? You guys throw away the tube when it's punctured?!!!! My tube has 6 patches on it and it's still running strong.

Great video! Precise, concise, to the point with no fluff. Cheers!

You're the man, Calvin. Very well done instructional.

Straight forward and helpful. Thank you Calvin.

TAFT CA with out Torrance bike tires and tubes. 48 patches on 1 tube. This time i put an old inner tube over the inner tube. fits ok. I tried aluminum cans.

Con you fucking believe it for one second...1.3mil views on how to patch a tube....this is the surprise of my day so far !!!

You’re a legend!

You saved my ass today man. Good thing I had vulcanizing patches on me.

Bought new tubes for 5 bucks each at Walmart a lot easier than finding the damn leaks and waiting for it to dry out

Really like your videos Cal. Always somethung to learn.

Love this guy! Thank you for posting all of the very informative videos!!
