Technical Information

1
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).
2
Removing an inner tube
Remove the used inner tube using B'Twin tyre levers (item code 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 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.
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 rim. 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 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 with a screwdriver or a tyre lever, as you risk pinching and puncturing the inner tube.
6
Inflating the tyre
Inflate your tyre carefully, to the pressure recommended by the manufacturer (visible on the tyre sidewall in PSI or bars, 1 bar = 14.51 PSI). Regularly check that your tyre is in the correct position as you inflate it.
7
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.

Used for 2 to 8 weeks
Haven't had any problems with these they do what they say.
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.
