Stockage tips

Maintenance tips
To find out the size of your wheels, check the inscriptions on the side of the tyre. Always have a spare inner tube and a pump.

Worst inner tube in the market
Used for 1 week or less
I bought two thinking I’m having an awesome deal, unfortunately both of the inner tubes (in the same day) had at least two tears in each inner tube. this inner tube doesn’t even allow you to ride more than 10 mins. I have not used any tools so there no way I could have pinched them.. would not recommend
Response of the brand
I'm sorry to read that you had the same issue on two innertubes. It is strange that both went in the same way. I am very keen to find out more.
Are you able to send me photos of the innertubes as I wish to forward this on to our design team.
I look forward to hearing from you,

It's just a compact inner tube, and Sunday morning saver if anything goes wrong.
Only improvement would be to have a removable valve so you could add some tire sealant to forget about little punctures.

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

Does the job.

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.

This tube seems fine, I have tried the Decathlon cheaper ones and found them to b every prone to punctures.
No comment
Would have prefered a locking nut at the valve.
Used for 2 to 8 weeks
These inner tubes are good quality, based on previous experience, and the multi buy makes them an amazing bargain
