What inner tube?

phillondon

I have a Voodoo Bizango 29er. I went to Halfords and they said they don't have the right inner tube in when I went to buy a spare, but I should asked what type I need.

Can anyone tell me so I can get a few, thanks.

29inch mtb tube, not sure what valve though, will be Presta or Schrada.. Presta us a skinny valve, Schrada fatter.

Yea that was the issue I think, they didn't have the right tube for the valve I have. I'm not sure what the valve is myself and can't find a definitive answer online.

I think they said the tube they had wouldn't fit through the valve I have.

If it looks like a car valve it's Schrader, if it is skinny with a little knob that screws out it's Presta.

I guess that would make it a Presta. Any recommendations where I can get a few at a good price? Cheers.

On One normally have deals.

Loads on Ebay - bulk deal should be around £2 each or less.

For reference, would this be the right product?

Yep, but I wouldn't pay that for a tube.

£8 for 5.

Add one of these to get to the £9 free postage limit. Contains a useful tyre boot as well.

And you're done for years.

48mm valve length is fine for standard rims. If you have deep section rims get 60mm. I generally get longer ones anyway.

phillondon

Thanks mate. That's great. Not sure what the rims are. How do I find out?

Sorry for the questions, I'm literally totally new to all of this!

lostboysaint

What's an inner tube? The fact that you need one tells you that now is a good time to set it up tubeless

cooldad

Either would be fine. Look like fairly standard rims.

as above, presta valve is standard in the Bizango. ( think yourself lucky that your nearest store remembered what valve the bizango had - when i got mine ( used ) i was given all the other bits he had too, one of these bits was a spare tube ( a continental one ) & looking through all the bumf i also got with it i found the receipt for the bike & it was supplied with the bike when bought new so not a later buy made in error & they supplied a schrader valve so completely useless lol - still got it in the loft somewhere as i dont want to chuck it out & neither do i want to cut it up to make some covers for the road bikes CO2 canisters either lol

you want ones that cover the 2.25" tyre size ( i think thats what the ardents are that come as standard ) you may get away with slightly less size like linked to above cover BUT they MAY ( loads a folk have had no troubles though ) puncture easier as they will be more stretched than they are meant to be, on the plus side though, they will be slightly lighter than tubes that fit your tyres properly ( this is why many folks go 1 size down on the tubes to reduce weight )

i stocked up on boardman innertubes when they were getting shut @ £1 each a while ago - some may still be available locally if your lucky ( chuck in british cycling discount & 20% off online orders offers & it meant mine came in dammmed cheap - got enough for a few spares for all my bikes

phillondon

Thanks guys. Great info.

So what exact tube size should I order? The ones linked above only go to 2.25 inch width. I think.

cooldad

Stop overthinking it - they are inner tubes. They will be fine.

If you look at your tyres you'll see they are 2.25 wide. The difference is a tenth of an inch.

cooldad

Blow one up outside a tyre and you'll see how big they get.

phillondon

I'm not over thinking it, I just really have no idea. One person tells me get this, another tells me get this! I just want the right size for my wheel, that's all.

So anyway, I'm gonna get a load of the 2.25 inch, but does it matter what valve length you get? 48mm or 60mm?

cooldad

Are you taking the p1ss?

phillondon

Again, I don't know anything about this stuff, I'm completely new to it. I don't want to be on the side of the road trying to replace the inner tube and I've got the wrong valve length. How am I supposed to know what option to choose when there's two to choose from? I don't just have an inherent knowledge of it do I? You have to get the right stuff, I don't want to guess.

So no, I'm not taking the p1ss. But whatever, forget it.

Later.

You need a 29" inner tube with a presta valve.
Inner tubes generally come in various widths so get one that accommodates your tyre size.
For example, Continental do a 29" inner tube that has a 60mm long presta valve and is for tyres from 1.75" to 2.5".

All the info is printed on the box the inner tube comes in.
It's really very simple.

If you really are new and clueless then start learning how to maintain your bike and perform minor repairs as soon as possible. If you don't know what an inner tube is how will you be able to change one if you get a puncture? You will save yourself a lot of hassle and cash. Check out the Park Tools website for guides and instructional videos.

i think he was suprised as he already answered that particular question in one of his earlier posts ( just under the link to the innertubes themselves ) ( & i am possibly partly to blame too as my post may have made you ask more questions than you were going to do anyway )

basically he states 48mm should be fine for almost all standard rims but 60mm ones will defo fit too ( if your unsure go long as longer just means they will poke out further ( as well as look strange on bikes with really thin rims - i have 60mm ones on my cheap commuting road bike & it does look a little out of place as it has really thin rims so you see like 55mm of valve rising from the rim lol

only difference being, longer valve length is generally for the really DEEP rims found more often on road bikes ( usually called aero rims or somesuch ) so that you dont have to use valve extenders to be able to pump them up, downsides of longer valves on normal bikes is as previously mentioned they can look out of place on some bikes, they weigh a little more than shorter valve tubes due to more valve ( more a road bike - every gramm saved counts type problem ) & if your a little hamfisted when pumping em up they can be easier to break as they dont have the taller rim to support the upper section of the valve so you can apply more bending forces to the base of the valve easier ( as i say, you gotta be really hamfisted though - not managed to snap on yet but i did forgot to disconnect the pump on mine once & tried spinning the wheel & only managed a minor bend in the valve )

I know what an inner tube is, and I am confident that I can change one as I've got instructions saved on my phone, and a video. It's just the specifics of what options I need for my particular wheel and tyre. That's all I want to know. The box might have the information printed on it but what good is that to someone who doesn't know how that relates to what they have?

The site linked to me above has a variety of options to choose from, you can't expect me to just guess.

I completely missed the valve length comment, that's all. I see it now. Thanks,

Now I know that I need a Presta as my tyres valve is smaller than the Schrader, I also know that I can use a 2.125 tube as it will stretch, I know what valve length to get too so now I know exactly what to get.


Thanks again.

Thanks for the information, that's all really helpful.

Thanks.

No Problem ( new here myself ) but i have been a member on a few motoring forums & can kinda see why regular posters on here can get a little short with some questions - no excuse for it but just saying i can see why some folks do it

it may be a VERY popular question(S) & they may be sick of answering them ( i stopped going on the motoring forum i used to be on when folks started getting short with new folks & just replying with "Do A Search" - yes it will get annoying for the regulars but does not warrant that.


the info on the box thats important for tubes is the size & valve type ( so 29 / 27.5 / 26 / 700C / 650c presta / shcrader etc ) the other bit ( 1.75-2.1" etc just means that tube is meant for tyres sized between those figures as a min and max ( if your tyre size is one of those figures or between these then your sorted, if its below try & find another tube as it may not inflate properly inside the tyre & cause a few issues & if your tyre is above then again try another tube if you can but if its all you can find then worth a shot so long as its not too far above ( as mentioned they do stretch BUT they also go bang very loudly if you take em too far lol - 2.1 in a 2.2 tyre should be perfectly fine for example, a little stretched but nothing major - one of my bikes has 4" wide tyres & seen folks on here mention using 3" max innertubes on them to save many gramms of weight from the wheels ( 550gram for the proper tube verses 350 gram for the stretched one etc - too cowardly to try that stretch myself so plumped for some heavy ones instead for my spare lol )


tools to invest in for a tube change ( ANY bike really ) is a decent set of tyre levers, you may not need them BUT they are a godsend if you have an arse of a wheel tyre combo, out of all the bikes i have, there is 1 that needs no levers to remove & refit tyres & tubes, 1 that just needs the 1st & last bits of tyre levering & the rest produce many, many utterances of language unfit for reproduction on a public forum as they are that tight a combo.

the cheapy ones you often get in repair kits & such are often useless unless its a tyre that really dont need levers so a decent set of levers are a godsend for stubborn tyres - i either have pedros levers if you can find em cheaply or a pair of topeak 1.2's i think they were ( they were a steal on amazon one time as a order padding to get free delivery lol but i prefer the pedros plastic levers for the tight tyres )

The Rookie

You can stretch tubes a long way, I used to run 1.0-1.5% tubes inside 2.25" tyres as they were lighter, I've given 26" tubes to a rider on a 29er when he got a second puncture and it worked just fine.

phillondon

I just want to say thanks for the help. I got 5 inner tubes and a puncture repair kit. Also I got a drinks bottle for free so I'm happy.

Many thanks guys.
