Replacing 1 year old tubes that are failing

I bought these tubes to replace old ones that came with my pair of foldable bikes. After more or less one year, there has been flat tires out of nowhere (no punctures on tyres or evidence like nails or thumbtacks). It just got old and weaker sections end up leaking.

So far so good

Upon fitting the inner tube to the tyre with some air in it, it seems the tube is longer than the tyre. It kind of folds a bit (BTWIN Foldable bike) after fitting.Who knows if it's still folder once fully inflated. So far it still holds the tyre and works....

Quality or installation seems to be the problem.

After getting the tube replaced, we found out a puncture again the next morning.

Thank you for taking the time to give us your feedback. Inner tubes and tires are wearable components and it is possible for punctures to happen due to external factors and internal problems like pinching and spoke piercing. Please get the wheel diagnosed again for any such signs. Feel free to write back if you have any questions.

Good quality at low cost

Bought a pair for my fold up bike and sons BOX. These are superior to the cheap innertubes sold by other shops.

Poor quality

I think maybe on this occasion it would have been better to have paid for a better quality tube

Dear Sir,
I'm sorry to read that you have had a puncture.

Se pincha fácilmente

Compre la bici en decathlon y al poco tiempo se pincharon la rueda de delante y de detrás, y las sustituí por estas cámaras y el segundo dia que salí por la ciudad volvimos otra vez con la rueda pinchada


Me lo han traído en 2, unos fieras, a ver si dura.

De 20x2.2 está bien pero 2.4 mejor

Hola muy buenas, Me gustan mucho por la calidad. Pero les falta ser un poco más anchas de tipo 2.4 para cubiertas más gruesas. Un saludo

Additional Product Information

How to choose an inner tube

Check the information indicated on the sidewall of the tire (diameter and width). For example, 20 x 2.10 means your tire is 20 inches in diameter and 2.10 inches wide. On the tire sidewall, you will also find the dimensions in mm in ETRTO international units. For example, 50-406 means a tire that is 50 mm wide and has an inner diameter of 406 mm (approx. 20 x 2.00).

Removing an inner tube

Remove the old inner tube using B'Twin tire levers

Checks to carry out before installing an inner tube

Check the condition of your tire and replace it if necessary. Make sure no objects are lodged in the tire. Check the condition of your tire 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.

Mounting the 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 tire so that it fits inside the rim. Take care not to pinch the inner tube when fitting.

Mounting the tire

Start mounting the tire at the valve. Finish mounting the tire at the valve to avoid pinching the inner tube. Never mount your tire with a screwdriver or a tire lever, as you risk pinching and puncturing the inner tube.

Inflating the tire

Inflate your tire carefully, to the pressure recommended by the manufacturer (visible on the tire sidewall in PSI or bars, 1 bar = 14.51 PSI). Regularly check that your tire is in the correct position as you inflate it.

Tip from the pros

To prevent any puncture from pinching and to achieve the best performance, we recommend checking and, if necessary, pumping up your front tire before each ride.

Complementary products

You'll need a tire lever (reference 8047839) to change your inner tube. If you want to repair a punctured inner tube, you can use repair patches (reference 1779640) or self-adhesive patches (reference 8380935)



Product testing

To guarantee optimal quality, 100% of our inner tubes are inflated for a period of 8 hours.

Storage instructions

Carry your inner tubes in a container to protect them from getting punctured (B'Twin carry case, original packaging, etc.).

Care instructions

To find out the size of your wheels, check the information printed on the tire wall. Always carry a spare inner tube and a pump.
