Technical Information

How to choose your inner tube
Check the information indicated on the sidewall of the tyre (diameter and width). For example, 26 x 2.20 means your tyre is 26 inches in diameter and 2.20 inches in width. On the sidewall, you will also find the dimensions in mm in international ETRTO measurements. For example 50-559 means the tyre is 50 mm wide with an inner diameter of 559 mm (or 26 x 2.00).
Removing an inner tube
Remove the used inner tube using B'Twin tyre levers (item code 8047839).
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. A rim strip that is even slightly bent can cause punctures. Check that your rim does not have any other issues that could damage your inner tube.
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.
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.
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.
Tip from the pros
To avoid punctures caused by pinching and get more out of your tyres, we recommend that you check your tyre pressure before each ride and pump them up if necessary.

Response of the brand
Dear Pavan,

Thank you for sharing your useful review. The puncture protect is definitely a very helpful product for off-road or regular users. We really appreciate you taking time to share your experience with us. Happy cycling

Failed to self-seal
Used for 1 week or less
Punctured on only my second use (on not particularly rough roads/tracks). Self repair failed to work and I had to walk home and resort to the good old puncture repair kit.
Response of the brand
I'm sorry to read that the innertube did not seal itself. Holes made by thorns, small pieces of flint or small pinch flats should seal up with no issue as long as you keep on riding (important not to stop riding), the motion of the wheels spinning plugs the hole. If you continued to ride and the puncture persisted, the hole may have been too large.
If you believe the item to be faulty then please feel free to return it to us for a refund or an exchange.

Response of the brand
Hello Punith,

Thank you for taking the time to give us your review. The inner tube usually heals staple pins and smaller punctures. It may not be able to heal nail piercings. I suggest you try a tire liner to reduce the number of punctures.  I remain available for more questions.

Failed as a spare, faulty valve
Used for 1 week or less
Intended as a spare, had a puncture and did a road side swap, only to realise that the tube had a faulty valve and could not inflate. Maybe I just have a stroke of bad luck.
Response of the brand
Hi Yak, thanks for your feedback! We will definitely share it with the Btwin product manager. You may bring the inner tube back to any of our stores for an exchange!

Great tube at an even better price
Used for 2 to 8 weeks
So far so good, great price and two weeks puncture free and counting
Bad quality valve
Used for 1 week or less
I used it for the first time and as soon as I left home, after 5 minutes cycling the tyre was flat. I checked it and there did not seem to be any problem so I inflated the tyre again but the same happened. I checked the valve and it tourns aout that after pumping air, when I pressed a little bit with my hand I could hear air coming out. This is not fine, I read some comments of people having problems with the valve of this product. I think perhaps some are OK but I would not risk to but it knowing that it is a recurrent problem.
Unfortunately, it's been more than a month I bought it so I don;t think I can claim my money back but hopefully it will help other people to take a good decision.

26x1.7-2.2 Self-Healing Inner Tube - Schrader Valv
Used for 2 to 8 weeks
I bought a second one of these auto-repair tubes last week for my other tyre.
But after filling the air, just as I was about to put the cap on, I noticed that some air was coming out of the valve. I then checked my other wheel which had this same self-healing tube fixed couple of months before. To my surprise, it also had a similar air leak from the valve. I still used it for a couple of days and the loss of air pressure is not noticeable. I am not sure if this is the way they are designed or whether I got faulty pieces. I am actually confused and hope to check with the store one of the weekends. I've not yet got a flat tyre situation to see the auto-repair in action (or did it happen and it auto-healed and I did not know!!?, which would be cool).
Response of the brand
Hello Rajesh, 

Not sure how you noticed that the air is leaking from the valve because if it was so evident the tire would have been flat in a couple of hrs. The fact that it is happening in the other tire as well is very surprising. I suggest you visit the closest Decathlon store to have a quick check. 

Inner tube
Used for 2 to 8 weeks
Self sealing inner tube, working great
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. 

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.
