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).
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.
Self sealing inner tube, working great
The valve got detached automatically just after 1 ride. The valve cannot be attached even with strong glue, rendering the tube useless.
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.
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.
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.

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.
VERY EASY INSTALLATION...DO-IT-YOURSELF
ITS SELF HEALING FEATURES
next to useless the bike guy at the shop said it would work fine yet i have a flat tire. avoid at all cost
Easy to install
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
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.

Two inner tubes in a year - 1st one replaced after bad puncture ( which auto filled so I was able to cycle 5 miles to get home) 2nd tube I still have in and nice to know you do not need to stress about getting puncture. Recently bought two tubes for my son who has had numerous punctures- been puncture free for two months
Easy to fit
The staff in the cycle department are always helpful and happy to assist
Staff were very helpful in changing the tyre
