Hi Wai Meng,

We are sorry to hear about your situation. It might be damaged due to a defect or during installation as the tube is not supposed to leak after 3 days. 

If possible, you can visit any of our Decathlon stores to get a free replacement + Installation.

We hope to serve you better in the future :)

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.

Hello,
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

Additional Product Information

Composition

Main fabric : 90.0% Rubber - Isobutylene Isoprene Rubber - Butyl, Main fabric : 10.0% Brass

How to choose an inner tube

Check the information indicated on the sidewall of the tire (diameter and width). For example, 26 x 2.20 means your tire is 26 inches in diameter and 2.20 inches wide. On the tire sidewall, you will also find the dimensions in mm in ETRTO international units. For example, 50-559 means a tire that is 50 mm wide and has an inner diameter of 559 mm (approx. 26 x 2.00).

Removing an inner tube

Remove the used inner tube using B'Twin tire levers (item code 8047839).

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

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 by mounting the tire onto the wheel on the opposite side to 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 avoid punctures from pinching and for best tire performance, we recommend that you check your tires and inflate them to the suggested pressure before every ride.

Weight:

5.2 oz

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 that protects them from perforations (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.
