Hello Mahakpreet,

I use an adapter so that I can fill air using the pump that's good for Schrader valves. This particular tube seems to have a problem where the air leaks while pumping air.
Excellent

Response of the brand
Hello Harshad, 

Thank you for taking the time to give us your review. Since the inner tube is a product which is subjected to wear and tear and tough climatic conditions there are chances of unpredictable punctures.  Apologies for the bad experience. I suggest having a tire liner installed during long distances in order to prevent flats from small sharp objects.

good value for price

By far the best valued inner tube I've used and ever seen.

Does the job.

Effective.
Unreliable
Used for 3 to 6 months
Bought a special pack of eight when I had just bought new wheels and tyres. Of the first two tubes I went to use, one of the tubes already had a puncture (pin hols in two spots, as if punctured whilst still flat and packed. I opened another tube and installed it, fine. No issues. I complained about the one tube and after two weeks I received a fresh box of eight (not sure why they didn't just send one but I sort of glad they didn't).
Bike hit by a car so needed new wheels and tyres again. Installed two brand new tyres with the bike still in the clamp to have a chain and front mech fitted. Rear tyre wouldn't inflate. Removed the rear tube and yep, two pin holes at the same point in the tube, as if a pin had been pushed right through. That's a failure rate of 2 from 5 and that's BEFORE they'd been used. They arrived with punctures. Replaced the rear after testing it first for punctures. The innertue was not losing air after putting a small amount of air in before putting it on the wheel. Inflated the tyre to 120 tpi (tyres are min 100, max 150 23 x 700 Rubino Pros) and it seemed okay. Started to inflate the front and BANG!, rear tube failed. That's 3 from seven. Now I was carrying two spares with me on all rides over the summer and thankfully I never had a puncture. I have zero faith in the tubes. Two arrived pre-punctured and one suffered a catastrophic failure. This is not acceptable, using them feels like a lottery.
Response of the brand
I am at a loss to explain why you had so many issues. We sell 100's of thousands of these each year and either you've been unreasonably unlucky or something is afoot. I will forward your experience on to the product manager to see if they have had similar feedback. Ordinarily I would ask you to check your tyre, rims, rim tape and installation technique but in this instance there is no need as you had the issues before hand.
Please don't hesitate to return the said items to us for a refund if required.

Size is 18-25mm, does anyone even make 18mm tyres? Anyway these are way too narrow for 25mm tyres. I doubt they would even be suitable for 23mm. I bought 2. I am going to have to throw them away.
Response of the brand
Dear Sir,
Thank you for posting a review of your experience with the innertube. I'm sorry to read that they are not compatible with your tyres (Lithion 2).
The next model up (700x25-32) may be a better option in this case.
If you're not happy with your exising innertubes then please feel free to return them to us for an exchange for the next size up.
Regards,
Peter Lazarus UK Cycling Market Manager DECATHLON

This tube seems fine, I have tried the Decathlon cheaper ones and found them to b every prone to punctures.

Would have prefered a locking nut at the valve.
