Good value inner tube

The quality seems fine, price is low. It’s increasingly difficult to find tubes with Schrader valves. This fits the bill at an agreeable price.

Buy a different one

I bought two of these and both of them blown up. The refund was rejected due to 'this is not a quality issue, I might have used the tyre leaver incorrectly'. Fair enough, I did not use tyre leaver at all. I bought the same inner tube with presta valve and used tyre leaver and it is good. I am sure this batch had quality issue so ended up in Halfords.

Good quality, good price

So far so good, no punctures!

Good price. Keep a few spare in your cupboard.

Very competitive price. We alway keep a few in a cupboard for when things go a bit wrong and we need to replace an inner tube on a Sunday night.

Good quality great price

In the last 2 weeks 3 of these tubes got a puncture within hours of changing them. I can't say I'm impressed with the quality, will definiteley switch brand.

thank you for your feedback regarding these inner-tubes. I'm sorry to read that you had so many punctures. It's hard to say if it was indeed the fault of the inner-tubes as so many other factors could be at play. Indeed if you feel they are faulty or not fit for purpose, please feel free to return them to us with your receipt for a refund or an exchange.
Peter, Cycling Manager, DECATHLON

Very good

Additional Product Information


Main fabric

  • 10% Brass
  • 90% Rubber - Isobutylene isoprene rubber - butyl

How to choose your inner tube

Check the information indicated on the sidewall of the tire (diameter and width). For example, 700 x 35 means your tire is 700 mm in diameter and 35 mm wide. On the tire sidewall, you will also find the dimensions in mm in ETRTO international units. For example, 36-622 means that the tire is 35 mm wide and has a 622 mm internal diameter (or around 700 x 35).

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.

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 to protect them from getting punctured (tool drum, original packaging…).

Care instructions

Wheel size is printed on the sidewall of your tire. Always carry a spare inner tube and a pump.
