Technical Information

1
How to choose your inner tube
Check the information indicated on the sidewall of the tyre (diameter and width). For example, 700 x 23 means your tyre is 700mm in diameter and 23mm wide. On the sidewall, you will also find the dimensions in mm in international ETRTO measurements. For example: 23-622 means your tyre is 23mm wide with an inner diameter of 700mm (so 700 x 23).
2
Removing an inner tube
Remove the used inner tube using B'Twin tyre levers (item code 8047839).
3
What to check before installing your new 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.
4
Fitting your inner tube
Pre-inflate the inner tube slightly to avoid pinching. Insert the valve, making sure you are using the correct valve for your rims. 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.
5
Mounting the tyre
Start by mounting the tyre onto the wheel on the opposite side to the valve. Finish mounting the tyre at the valve to avoid pinching the inner tube. Never mount your tyre using a screwdriver or a tyre lever as you risk pinching and puncturing the inner tube.
6
Inflating the tyre
Inflate your tyre carefully to the pressure recommended by the manufacturer (visible on the sidewall of the tyre in PSI or bars, 1 bars = 14.51 PSI). Regularly check that your tyre is in the correct position as you inflate it.
7
Tip from the pros
To avoid punctures from pinching and for best tyre performance, we recommend that you check your tyres and inflate them to the suggested pressure before every ride.

not happy about the 20% price increase but still the cheapest inner tubes anywhere.
Bad Batch
Used for 1 week or less
Awful quality, you get what you pay for here with this product. Inners cannot handle the PSI suggested upon the packaging.
I went through two sets in one week, back off the valve splits open.

Constant puncture
Used for 2 to 8 weeks
Had these inner tubes put on in the shop, within 3 days both had punctured, both next to the valve leading to suggest bad batch... so guy in shop replaced both for two new pairs, 2 weeks later, I am at the side of the road again with punctures in both inner tubes and the exact same spot.
Response of the brand
Dear Sir,
I'm very sorry to read that you have encountered such issues with the innertubes. Could you kindly tell me which store replaced the items as I wish to obtain a sample for testing. Could you also send me a photograph of your rime, more precisely a zoom in on the valve hole in the rim?
Regards,
Peter Lazarus, National Cycling Manager, DECATHLON

Heavier than top brand 'tubes but just the job unless you happen to be a gram conscious racing snake, if not go for it.

Easier to fit new than bother with a puncture repair at this price
Excellent
