BENEFITS

Compatibility

20", 1.7 to 2.2 cross-section tires
ETRTO 44/57 – 406

Waterproof

Optimized composition to guarantee your inner tube has a good seal.

TECHNICAL INFORMATIONS

How to choose an inner tube

Check the sidewall for tire information (diameter and width).
For example, 20 x 2.10 means your tire is 20" in diameter and 2.10" wide.
The dimensions in mm (ETRTO international unit) are also on the tire sidewall. For example, 50-406 means that the tire is 50-mm wide with a 406 mm inner diameter (approx. 20 x 2.00).

Removing an inner tube

Remove the old inner tube using Btwin 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’s even slightly bent can cause punctures.
Check that your rim doesn’t have any other issues that could damage your inner tube.

Installing the inner tube

Watch our video before you start.
Pre-inflate the inner tube slightly to avoid pinching.
Make sure you’re using the correct valve for your rim and then insert it.
Put the entire inner tube inside the tire so that it fits inside the rim.
Take care not to pinch the inner tube when installing it.

Installing the tire

Start installing the tire at the valve.
Finish installing the tire across from the valve to avoid pinching the inner tube.
Never install your tire with a tool or a tire lever, as you risk pinching or puncturing the inner tube.

Inflating the tire

Carefully inflate your tire 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.

Pro tip

To prevent pinching and achieve the best performance, we recommend checking and pumping up your front tire as needed before each ride.

Excellent value for inner tubes
Long (United Kingdom) Used for 3 to 8 weeks
Inner tubes for £3 you can't beat this price anywhere. I bought 2 just in case the tyres pop so hopefully they work.

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.
Response of the brand

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! :)

These tubes are faulty or lack quality
Aahan (India) Used for More than 2 years
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.

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
