Schrader valve tubes

All inner tubes from Decathlon are very durable and haven't given me any problems in over two years of use.

Top class tubes

It is not easy to find 26" tubes with the longer 48mm valves in schrader. If you have deep profile rims these long valves are essential. Good quality tube to boot. Top product.

Couldn't Hold The Air More Than 1day.

Won't go for it again as it doesn't hold the air for more than 1day. So if I have to go cycling daily then have to pump air daily.

Hello Suraj,

We are really sorry for the experience you had with the tube. It might be possible that there is a small puncture on tube. Now this can be a defect on the tube or it might have caused due to something on or inside the tyre.

I would recommend you to visit the nearest Decathlon store and get it checked. If the issue is related to the tube, we will be happy to replace it.

Let me know if you need any help for the same.

Very poor quality

Its very bad experience..I used this tube on 30th Nov 2020 and on same day it's punctured twice. Person who repaired( twice) has given response that material is too poor. Finally I have to replace it with local tube. Was not expected this from Decathlon

How to choose your inner tube

Check the information indicated on the sidewall of the tire (diameter and width). For example, 26x1.90 means that the tire is 26 inches in diameter and 1.90 inches wide. On the tire sidewall, you will also find the dimensions in mm in ETRTO international units. For example, 50-559 means that the tire is 50 mm wide with a 559 mm internal diameter (approx. 26x2.00).

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 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.
