Inner tubes have a big effect on the performance of your bike. Lightweight inner tubes will reduce rolling resistance and help you to ride faster, slightly heavier tubes will have better puncture protection and the wrong tubes..? They just won’t work.

In this guide, Daniel Lloyd takes you through the differences between schrader and presta valves, how to work out which tube size your bike requires, and how to decide on the material.

Do you run standard tyres with inner tubes or have you made the jump to tubeless? Comment below and let us know!

  1. Links at the end don’t work guys.

  2. Does 25c inner butyl tube can effectively fit a 28mm tire, in terms of safety, rolling resistance, and risk of punctures?

  3. There’s more to tube descriptions than you shared here. For example, I’m buying some Continental GP 5000 700 x 25 tires. My tube choices are…

    700 x 18-25 – Pv 42Mm Light 70G
    700 x 18-25 – Pv 42Mm – 100G
    700 x 18-25 – Pv 60Mm – 105G
    700 x 18-25 – 60mm PV Light
    700 x 18-25 – 80mm PV Light
    700 x 25-32 – Pv 42Mm – 125G
    700 x 25-32 – Pv 60Mm – 125G

    I’m assuming the "100G" is 100 grams and the lighter the weight, the thinner the tube wall. Pv stands for Presta and the number following is the length of the valve. I’m curious as to what the "light" is in reference to? Also, given that the 25s are right at the split point, would it be better to run the 25-32 tubes for puncture resistance or will they be too big and subject to folding/pinching?

  4. I have specialized 700×26 Turbo cotton tires with 700×20-28 48mm presta tubes. But in looking for more tubes online, most are either 18-25, 20-25 or 25-32 with either a 42mm or 60mm presta valve. Only specialized makes a 700×20-28 with a 48mm presta. If I want to order a tube other than one made by Specialized, will the 700×20-25 with a 42mm valve work? I have the DT Swiss R470 rims. Will the 42mm be too short?

  5. This guy is confusing (and confused I might say), lacks knowledge, and has really done a de-service to folks that need some clarity on tube sizes. Horrible content!

  6. Could you do a video about wheel sizes, and how to understand them. At least I find them pretty confusing.

    What if the inner tube is bigger? Will it be ok?

  8. Daniel González May 18, 2021 @ 1:23 am

    Hello. The inner tubes that I use on my Continental Gran Prix 4000 25mm are 700×25.
    Can I use the same inner tubes for Continental Grand Prix 4000 28mm?
    My internal rim width is 21mm (if important)
    Thank you.

  9. This is really helpful, thank you 🙂

  10. What about brand of innertube?

  11. Will a 700×23 tube work on a 700×25 tire .

  12. Walter Bellini May 18, 2021 @ 1:25 am

    Great tight and to the point video!
    Thank you

  13. Ahahahaa..that part made me laugh" when he was talking very professionally..and then he started bleeping.. "Where the Fuuuck is my… great advice also 👍

  14. Abdus Chowdhury May 18, 2021 @ 1:25 am

    I recently got a slime inner tube for a road tyre they are no good after two days of cycling I got a flat tyre. I thought they would last longer I thought they were close to being nail proof that’s how they advertise

  15. Carlos Richter May 18, 2021 @ 1:26 am

    Do not bash latex tubes, if you can afford them. You can much more feel your tires on the the road, easier to mount, ,less flats, easier to patch, and they are cool!

  16. Game And Scripts May 18, 2021 @ 1:27 am

    i have 20×2.35
    fuck mi life
    cant find it anywhere
    guess its time to buy a new bike

  17. Victor Guimaraes May 18, 2021 @ 1:29 am

    Can I use a 23c inner tube in my 25c tire, or should I stick with a 25c?

  18. Hi, can you advise me the right size inner tube for Schwalbe Marathon Plus 27.5×1.5 Tyre – SmartGuard. I’m looking for Schrader one. Thanks

  19. My tire says 26 in. but a 26 inner tube is way too big!! I think I need a 22 in. inner tube.

  20. my rim size is 32h ssw700. what is the range of tubes that would fit that rim size?

  21. My wheel says 700×25. So when purchasing inner tubes (specifically continental from Amazon) they give the size 700x25cc. Is it the same thing?

  22. Javier Rodriguez May 18, 2021 @ 1:35 am

    have you tested the Foss inner tube?

  23. My rim is 30mm is 42mm valve alright?

  24. worth noting that latex is 8 x more flexible than rubber so potentially MORE puncture/pinch flat resistance (if fitted correctly – note latex will stick to the tyre/rim tape so apply talcum powder prior to fitting). also best fitting tube/tyre with fingers only – this even possible with challenge Strada + Campagnolo Neutron Ultra’s – although I am also a massage therapist so have strong thumbs 😆

  25. Can I use 29er innertube (29×2.20) for 700x40c?

  26. Jose Francisco Alvarado Castro May 18, 2021 @ 1:41 am

    I’ve continental Grand Sport Race Tire (700×28) which tube I have to choose? I look into continental flyer and I found the Race 28 (700c) Wide is this the correct size?

  27. I have a questions for GCN: does lining your inner tube with an old inner tube help protect against punctures and flats?

  28. Joshua Gallegos May 18, 2021 @ 1:42 am

    Which inner tube would you recommend since I live in desert and my bike always gets flat

  29. Thank you, but nothing at all about brands in this video. I’m looking to buy 5 or 10 road tubes (700 x 25 Gatorskin tires). I don’t want to pay extra for branding, and also don’t want to get crappy tubes from a no-name brand that fail more often. For examples. has dirt cheap 10x Entity Inner Tube 700×18-28c Presta Valve 48mm tubes. But I’ve never heard of Entity and have no idea if they’re any good. On the other hand, $8 apiece for a tube that comes in a Specialized box seems completely stupid. Any thoughts?

  30. Joe Brockbank May 18, 2021 @ 1:44 am

    The links at the end of your video to click on one of your other videos does not work

  31. Can 23 mm inner tubes fit to 25 mm tyres?

  32. Nuggi Nuss Lover May 18, 2021 @ 1:47 am

    You forgot to mention the dunlop valve.
    Why am I mentioning this ?
    Because I want the whole world to laught about this piece of trash so it will finally not be used again.
    I hate it so much.
    It’s also the thing that i have the strongest opinion about regarding wheels & tires.
    I don’t care if butyl,latex, tubeless, schwalbe, conti, disc brakes… but man do i hate dunlop valves

  33. Markus Andreas May 18, 2021 @ 1:47 am

    Thank you so much! Really helpful 🙂

  34. Allan Pountney May 18, 2021 @ 1:47 am

    Great vid. So what do you recommend latex or standard ?

  35. 29” wheels (700)(52) what inner tube size will be best!!

    Will a 29 x 1.75-2.125

  36. How do i know how deep my rim is pls help

  37. Asadel Andrews May 18, 2021 @ 1:57 am

    He only went over adult bikes🤷🏾‍♂️

  38. The velux rim tape won’t hold latex tubes. They will pop through the spoke holes. Use strapping tape glued with pvc glue. I use old tape measure tape with electrical tape over it and contact cement under it.
    Latex tubes are much faster about 10 percent. Big difference!

  39. ML w4r legend gaming May 18, 2021 @ 1:59 am

    Will work?
    A 700x25c innertube to 700x28c tire

  40. Tubolito?

  41. Did he say "unless you’re running tubeless or tubeless"?

  42. Fernando Franchina May 18, 2021 @ 2:03 am

    hi guys, i bought my FIRST road bike and your videos are amazing!!, regarding this one here. Is not quite well explained HOW you measure, if there is a way the lenght of the presta valve? is from the lock nut to the tip of the valve? from the edge if the rim (in touch with the tire) to the tip of the valve?? I’m hesitating about buying a 42mm or 60mm valve tire.
    Thank you and sorry in advance if Im asking a stupidity hahaha

  43. Delmolition Man May 18, 2021 @ 2:03 am

    Not been on my bike for a long time, and want to get back into it.
    Just purchased new tubes and tyres, but no indication anywhere for max psi?
    Is there a common pressure as a rule of thumb? I am a failry chunky man (fat).

  44. Alonso Martii May 18, 2021 @ 2:04 am

    So my bike is a hybrid, and it uses 700×32c Michelin tires. Usually I see at the bike shops or online. 700×25c-32c and 700×32c-47c? I’d like to have some backups while on the rode.

  45. You forgot dunlop valve

  46. Richard Pinilla May 18, 2021 @ 2:08 am

    Nice explanation

  47. on average how long are the valve on a hardtail inner tube ? 27.5

  48. Great video for FNG like me!!!👍👍👍

  49. Christopher Doherty May 18, 2021 @ 2:12 am
