Technical Information

1
How to choose your inner tube
Check all the information indicated on the sidewall of the tyre (diameter and width). For example, 26 x 2.20 means a tyre with a 26 inch diameter and a cross-section width of 2.2 inches. On the sidewall of the tyre you will also find the dimensions in mm expressed in ETRTO international units. For example, 50-559 means the tyre is 50 mm wide with an inner diameter of 559 mm (approx. 26" x 2").
2
Removing an inner tube
Remove the used inner tube using B'Twin tyre levers (item code 8047839).
3
What to check before installing your new inner tube
Check the condition of your tyre and replace it if necessary. Make sure no objects are lodged in the tyre. Check the condition of your tyre rim strip. Even slightly bent rim strips can cause punctures. Check that your rim does not have any other issues that could damage your inner tube.
4
Fitting your inner tube
Watch our video before you start. Pre-inflate the inner tube slightly to avoid pinching. Insert the valve, making sure you are using the correct valve for your rims. Put the inner tube entirely inside the tyre so that it fits inside the rim. Take care not to pinch the inner tube when fitting.
5
Mounting the tyre
Start by mounting the tyre onto the wheel on the opposite side to the valve. Finish mounting the tyre at the valve to avoid pinching the inner tube. Never mount your tyre using a screwdriver or a tyre lever as you risk pinching and puncturing the inner tube.
6
Inflating the tyre
Inflate your tyre carefully to the pressure recommended by the manufacturer (visible on the sidewall of the tyre in PSI or bars, 1 bars = 14.51 PSI). Regularly check that your tyre is in the correct position as you inflate it.
7
Tip from the pros
To avoid punctures due to the inner tube being pinched, and to get the best performance out of your tyre, we recommend checking your tyre pressure and inflating it if necessary before each ride.

Leaking valve
Used for 1 week or less
The valve got detached automatically just after 1 ride. The valve cannot be attached even with strong glue, rendering the tube useless.
Response of the brand
Hello Srijith, 
 
Thank you for taking the time to give us your feedback. The inner tube valve breaking is uncommon. The valve may have been installed incorrectly or the product itself may be defective. Please take the defective product to the closest decathlon store and they will let you know if you can get a replacement after examining the inner tube.

Self sealing inner tube, working great
Nice idea...
Used for 2 to 8 weeks
So I thought I would replace my old inner tubes with self sealing ones.... nice idea.
So first outing, great ride out of about 10 miles just to check everything OK.
Second outing my front tyre was a bit soft so when to inflate... unfortunately it appears the valve has broken and the sealant has filled up the valve and sealed it completely... unable to put any air in but on the upside will not deflate any more.
Downside is .... in order to fit a new innertube I have had to slash the self healing one to get it out ... so the incentive lasted one ride - not really value for money then.
Response of the brand
It sounds as if the valve is blocked. It can occasionally happen to self sealing innertubes from all brands. A valve can be removed and cleaned and replaced. Alternatively you can return it to us for a replacement.

it works
Used for 2 to 8 weeks
got flat on my way to work but still made it all the way to my work-place. I left my bike for a couple of hrs and when I got back to check on it the tyre was completley flat. I took the wheel off for repair but then I decided to pump some air in and see how it holds. At first it was losing air but then after giving it a spin it sealed itself :) Just to make sure I left it for a few more hours to see if it was going to be fine and it was. Thus there was no need to fix my tyre (inner tube) and I got back home with no issue.
does not work at all
Used for 2 to 8 weeks

I'm sorry to read that you have a flat tyre.
I'm very interested to hear more about your puncture and why it did not remain inflated when you were riding. I want to feed this back to b'Twin as it will be very useful information to understand what went wrong. Would you mind replying to me?

I bought these after a spate of punctures and with a new tyre, set off confident on my commute, 15 miles in and a saftey pin had gone through the side wall. Never mind I thought i'll pull it out and my brand new self sealing inner tube can shine, spin the wheel still going down , put more air in still going down spin the wheel with more air still no joy spent as long trying to get it to seal as it did to change. Got home and part inflated it and the goo bubbled out of a small hole I left it hanging with the hole at the bottom hoping it might work. After a week and still not sealed I binned it, complete waste of time and money.
it fitted the rim
it didn't work
Response of the brand
Hi Darren,

Thank you for taking your time to review the self healing inner tube.
It is strange that the sealant did not work as it should, you have done everything correct in regards to keeping the wheel spinning etc to get the sealant into the hole. The only thing I can think of is that the hole was bigger than the 3mm that it will seal up to. I have been using the road version on my bike and it worked well after riding over some glass.

I'd return the tube to your local store for an exchange/refund as it has not done the job it is designed for.
