Inner Tube.

Bought for back up on my rides on my newer bike, something you hope you'll never need but worth carrying. Decent quality and price.

Emergency purchase

Fitted perfectly with unusual size

Failed right out the box

Manufacturing defect ; small hole in seam meant this failed before I could use it. Not much good when you are half way to nowhere and have a genuine puncture .

Hello, I'm sorry to read that you encountered a problem with your inner- tube. This is a very rare occurrence as I have not had feedback on this issue in the past. You are very welcome to return it to your local store for a refund or exchange the next time your pass by one of our shops. I have fed back your comments to the b'Twin team to bring the matter to their attention. Regards, Peter Lazarus UK Market Manager - Decathlon

Nice Product


Initial Impression is quite good

I have been regularly paying minimum 500-550 bucks for new tubes. Finally got my hands on Decathlon tubes. Seems great for a good price. Just swapped it myself seeing videos on YouTube and cost me a fraction of getting it done from a store.. Hopefuly the experience is going to be good. Fingers crossed. Carrying these as spare on long rides as well.

Quality & not much expensive

perfect for for 29x27.25

Additional Product Information



  • 100% Rubber - Synthetic

How to choose your inner tube

Check 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, 50-584 means that the tire is 50 mm wide with a 584 mm internal diameter (approx. 26x2.00).

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 prevent any puncture from pinching and to achieve the best performance, we recommend checking and, if necessary, pumping up your front tire before each ride.
