Good tubes at a decent price.

Needed 80mm tubes for my new carbon wheels. I’ve only had them for about a week and have put about 100 kms them. No issues so far. I keep them at around 95-100 psi and they are holding the pressure.

Great tubes for price

Purchased these inner tubes from Decathlon. Excellent tubes for the price. Would buy them again

Snapped stem in pump

I had a puncture on a long ride and pulled one of these out as my spare, I had some pressure going in the tube until the pump was hissing at the head and there was no back pressure - I also couldn't remove the pump from the stem. The threaded part of the stem had snapped off inside the pump, also trapping the locknut on top of the presta valve - So I had to carefully wiggle the valve thread until it snapped to get the pump off without losing pressure (My pump was now useless) Very lucky it kept some air but also a very surprising point of failure I've never seen before, hopefully a one-off as the second tube seems ok. On a plus Decathlon did happily replace the pump and fit another tube I had FOC so no complaints there.

Holds pressure really well unlike the big brand it replaced that constantly leaked from the valve.

How to choose your inner tube

Check the information indicated on the sidewall of the tire (diameter and width). For example, 27.5 x 1.90 means a tire with a 27.5-inch diameter that is 1.90 inches wide. On the tire sidewall, you will also find the dimensions in mm in ETRTO international units. For example, 50-584 means your tire is 50 mm wide with an inner diameter of 584 mm (approx. 27.5 x 2.00).

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.
