  1. Thank you for a clear precise description for first timers like myself. Very helpful!

  2. Okay I don’t know why but every time I pump my tire. It takes the air in. Right when it’s about to get full with air. The air just start going out crazy. I have a Presta valve. What should I do?

  3. OMG YOU JUST SAVED ME!!!!!,,,I didn’t know that you have to loosen the top of the presta valve,,,,,,,oh boy,,,,,,hugs and kisses for you!!!!!!!!!!!!
    GOD BLESS YOU!!!!!!!!!!!

  4. Excellent video. Just started road biking and greatly appreciate this.

  5. What pump does he have?

  6. Very helpful info 👍

  7. The gauge on my pump works but it doesn’t engage when I pump. The needle goes up when I pump but goes back down to zero once I reach the bottom. Any suggestions?

  8. Thank you very much for your help

    This is very interesting, thanks for this informative video. My road bike tyres states that it should be inflated to 100-130 psi (presta valve). But for some reason, when I start pumping my tyres I’m only reaching 60 psi and I’m no longer able to really keep pumping it – hard resistance feeling.. My pump is struggling to push anymore air in & feels like it’s going to pop. Is that an indication that I have wrong tubes inside my tyres? The pumps gauge indicates it is more than capable to pump more than 130psi. Thanks in advance for sharing your knowledge!

  10. Thanks! I appreciate the detailed and patient rundown 😊

  11. Your videos are awesome and informative. It will make anyone fall in love with cycling. I have learnt a lot about MTBs from GCN channel. Thank you for the awesomeness. Keep it coming. 👍👍👍👍

    Thanks you saved my bacon today! I haven’t ridden the bike in a while and totally forgot how to work this thing.

    Came here knowing how to inflate tyres. Still watched the whole video. Kudos, I wish my teachers were half as good as you are boi

  14. Had some trouble with presta valve,but this video sorted me out in a matter of few seconds,thank you very much. 🙂

  15. Thank you for posting this video. It helped me a lot.

  16. Thank fuck for slugssy. You saved my day! Hero xx

  17. Thanks, very informative 🙂 Literally struggling before watching this video. No information is ever trivial.

  18. My tyre isn’t accepting air at all no matter the locking of the pump 🙁 pls help

    Thank you, as a mom, this has been one of the best tutorials this year, now I’m a hero to my son as opposed to his dad who is in a trip. Thank you

  20. I already know all this but I came here b’coz GCN’s contents are worth watching…

  21. On my bike when I attach the pump to the Schrader valve I cannot pump any air into the tyre. The value is clear. What am I doing wrong?

  22. my bike has a prostor voel but it keeps unscuing every time i try inflate the tyres

  23. This guy… he just has a sexy voice.

  24. Christopher Jones November 29, 2020 @ 8:15 pm

    Awesome. Thanks!

  25. Yeah fuck I bought some Bridgestone Dragonfly mouth pump and no one told me I needed valve adaptors…
    Now I’ve almost let out all the air from by back tyre and have to wait for the adapters to wait before I can fill ‘er up… I am so tilted and wish I watched this video before. FUCK

  26. how do you check air pressure to Presta valve using pro bike mini frame pump tool ?

  27. This was heplful. Thank you

  28. Thanks a bunch. Just got a tube replaced (on a vintage 1968 Sting-Ray) and they used a Presta (and included the pump converter piece) but I forgot one step of the procedure and went half-mad trying to pump it up. Glad this video came up on my initial search. Don’t understand why everything that was once simple now has to be over-complicated and annoying.

  29. Thanks guys just filled my mtb tires for the first time thanks for the help.

  30. NEWBIE here…I’m trying to attach the nozel from the pump onto the shrader valve but it keeps sinking inside the tire so I cant push it on. Seconds when I pump, feels like something is blocking the air from going in the tire. The pump gauge doesnt stay up (needle goes up, then back down to 0)

    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!

  35. Great explanation of a basic skill. Thank you .

  36. A good bike pump we might need

  37. It’s actually sad that I’ve been riding my cycle for years yet I don’t know how to do this shit.

    lmao i didn’t know you needed to unscrew the valve and just shoved a pump onto it and bent tf out of my bike so yes there are people who need this (i’m also not usually that much of an idiot)

  40. Thank you so much you’re a life saver xxxx

  41. Just got my first road bike and this was extremely helpful!

  42. *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.*

  43. Uhmmm okay so, I’m struggling to actually pump air and I tried pressing on the tip of the valve, no fix. Any tips?

  44. Thank you very much for making this video. You saved us a trip. Thumbs up!

  45. Thank you! This is helpful to me as I try to learn more about my bike and maintenance 💯

  46. This was such a useful tutorial. Simply had no clue before and it saves me going to the bike hub, just to get my tires pumped. Thank you!

  47. Okay so I accidentally let all of the air out of my back tyre because i’m an idiot and unscrewed the thing completely before watching this video. Any tips on what to do now? I managed to pump the front tyre correctly after this but I can’t seem to get anything into the back one now

  48. Guys add this to the beginner playlist….it would be so helpful…I learnt it the hard way 2 months back because of the puncture 😂on my own
