Bad quality ?

Bought this article recently. First one had a puncture upon reception. I returned the article, and put the second inner tube on. One day in, and a short bike ride on the road, and the second one has now exactly the same problem, flat tyre. I was either very unlucky with a bad batch or the quality is poor. Awaiting for my replacement to assess this further ... But very disapointed so far !

I'm sorry to read that there was an issue with your innertube. I can assume you have thoroughly checked your tyre and rim tape to be sure. If so, It is hard to say why this happened.
If you believe the item is faulty, please bring it back to store for an exchange.

Split on seam

In use for a few months, I inflated the tyre to 60psi the day before a ride. After about 10 minutes very loud hissing and the tyre had fully deflated in a few seconds. Removed the tube and it had split along a seam. The bike was indoors and stationary, The 6mm split was on the inside of the tube next to the rim. Definitely not punctured, the rim tape is fine. Annoyingly I'll now have to replace both the tube and the Slime puncture liquid. Its lucky I wasn't riding when this happened as the deflation was very quick. I have used others which have been fine, hopefully this won't happen again.

I'm sorry to read that the inner-tube has split. This is an uncommon occurrence and is hard to explain exactly what lead to this.
If you feel the item was faulty, please return it to us for an exchange with your receipt.

Valve short for double wall rims

A pair of tubes at this price, is really an awesome deal. Tubes fit well, but the only problem is that the valve is little short and it hardly comes out about 3-4 mm from my double wall rim. (I have Montra Rock 1.0 / 2014).

Value for money

The tubes were delivered in time and I installed them myself. I am satisfied with the purchase and feel that they are the best value for money tubes I have bought in India.

Additional Product Information



  • 100% Rubber - Isobutylene isoprene rubber - butyl

How to choose an inner tube

Check the information indicated on the sidewall of the tire (diameter and width). For example, 26 x 2.20 means your tire is 26 inches in diameter and 2.20 inches wide. On the tire sidewall, you will also find the dimensions in mm in ETRTO international units. For example, 50-559 means a tire that is 50 mm wide and has an inner diameter of 559 mm (approx. 26 x 2.00).

Removing an inner tube

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

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

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.
