Let down

Bought 2 of these. One to replace a used inner tube and one as backup to carry with me. Now onto my second one as the first one lasted about 15miles. Whilst riding the tube simply failed going totally flat within seconds. Upon inspection the tube has simply failed splitting around the valve and cannot be fixed. Fingers crossed this is a one off but now I'm conscience of a potential problem. Won't buy this product again.

Thank you for your review of this innertube. I have forwarded your feedback on to the team in charge of this item.
If the tube was faulty, please return it to us for a refund or an exchange with your receipt.

Simple but effective

Ideal for MTB and reasonably priced

Good quality product

Manufacturing quality of both rubber & valve is good. Sizing is perfect. No complaints at all.

Accomplishes its purpose.

Great choice for those ones who own a cycle brand different from the house's one, at an unbeatable price. Though 48mm valve is a bit long for my tyre, I recommend it.

Great value

These tubes work really well, as good as the big brands and far cheaper so represent great value.

Qualité à revoir

Cette chambre à air se déchire et se troue trop facilement. J'arrive même à la déchirer avec mes ongles !!!!

Additional Product Information



  • 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, 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. 26 x 1.90).

Removing an inner tube

Remove the used inner tube using B'Twin tire levers (item code 8047839).

Checks to make before installing your 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

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 by mounting the tire onto the wheel on the opposite side to 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.

Storage instructions

Carry your inner tubes in a container to protect them from punctures (tool drum, original packaging, or bag).

Care instructions

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