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.

Great value

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

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.

Light weight just nice

Please buy

Additional Product Information

Composition

Membrane/coating

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

How to choose your inner tube

Check all the information indicated on the sidewall of the tire (diameter and width). For example, 29x1.90 means that the tire is 29 inches in diameter and 1.90 inches wide. On the tire sidewall, you will also find the dimensions in mm in ETRTO international units. For example, 50-622 means that the tire is 50 mm wide with a 622 mm internal diameter (approx. 29x2.00).

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 rim strip and that it is positioned correctly. 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.
