A good quality tube at very reasonable price

Seems to be made from good thick rubber. Time will tell how good these tubes are in the long run for puncture resistance and general wear and tear

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....

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.

Good product with a video with clear instruction to change the tyre.

Good quality, durable

Schaefer Valve inner tube is authentic, durable and long lasting. Would recommend to use Schaefer products for B’TWIN

These tubes are faulty or lack quality

I have two Tilt 120 Folding Cyles. It's something with these tubes. They don't hold air well for even a week if I am not using the cycles and every time there's a flat tyre it's not because of a nail or something external. The puncture is always near the valve where it's pressed against the rim of the wheel. And once that is the case, any cycle repair shop you visit will advise you to change the tube because the fix won't last. Now I have to change tubes on all 4 tyres because I cannot trust when they'll go out. 2 front tubes (of the 2 cycles) gave in when I rode them a few days ago). I am going with a diff. brand for the tubes this time. If not for the tubes or the frequent loss of air pressure/punctures, I'd totally recommend Tilt 120 to everyone, including adults. What a shame! This must have been fixed by now.

good product

the product fits the bill.

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.

Is it suitable for the common mountain bike?

According to specification, it is within the range of the common low end mountain bike we see around us. In practice, I found it is not probably not going to fill up the wider outer tire as fully as the ones we have at the neighborhood bicycle shop, which is getting increasingly expensive to go to for replacement. I have using for sometimes and I would say if you are more conservative on the riding habits, it would not be a problem. Decathlon might want to consider narrowing down the range to suit the norm here.

Hi Sze Wee,

Thank you for your review for the 20" 1.7 to 2.2 Schrader Valve Inner Tube.

As there are various sizes/dimensions of tyres, the inner tubes that we sell caters mostly to our bikes in Decathlon. It should work the same as those selling our local bike shop.

The inner tube is compatible with the bikes that we sell as well as other brands. Yes, the tyre size might be the same but the width of the tyre might differ from brand to brand.

We'll bring your feedback to the brand to see how we can cater more to the SEA market. We, in Decathlon, always strive to make sports available to everyone via our products at affordable prices, and we hope you are amongst those that have benefitted from this objective. We hope to see you in our stores again! :)

Thank you and sport on safely! :)

Skate safe! Skate fast!

How to choose an inner tube

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

Removing an inner tube

Remove the old inner tube using B'Twin tyre levers

Checks to carry out before installing an 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.

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

Mounting the tyre

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

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.

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 tyre before each ride.
