Technical Informations

1
How to choose your inner tube
Write down all visible information from the tyre sidewall (diameter and width). For example, 26 x 2.20 means your tyre is 26 inches in diameter and 2.20 inches wide. 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 (approx. 26 x 2.00 inches)
2
Removing an inner tube
Remove the old inner tube using B'Twin tyre levers (ref 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 the 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.
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 from the opposite side of the valve Finish at the top of the valve to avoid pinching Never use a screwdriver or tyre lever to mount the tyre or you could pinch the inner tube and puncture it.
6
Inflating the tyre
Inflate your tyre carefully, to the pressure recommended by the manufacturer (check the sidewall, written in PSI or in bars: 1 bar = 14.51 PSI) Regularly check that the tyre is in the right position while inflating.
7
Tip from the pros
To avoid punctures from pinching and for best tyre performance, we recommend that you check your tyres and inflate them to the suggested pressure before every ride.

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.

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.
