BENEFITS

Compatibility

27.5" tires, with a cross-section from 1.90 to 2.50.
ETRTO 47/64 – 584

Waterproof

Optimized composition to guarantee your inner tube has a good seal.

TECHNICAL INFORMATIONS

How to choose your inner tube

Check the sidewall for tire information (diameter and width).
For example, 27.5 x 2.10 means your tire is 27.5" in diameter and 2.10" wide.
The dimensions in mm (ETRTO international unit) are also on the tire sidewall. For example, 50-584 means that the tire is 50-mm wide with a 584-mm inner diameter (approx. 27.5 x 2.00).

Removing an inner tube

Remove the old inner tube using Btwin 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’s even slightly bent can cause punctures.
Check that your rim doesn’t have any other issues that could damage your inner tube.

Installing the inner tube

Watch our video before you start.
Pre-inflate the inner tube slightly to avoid pinching.
Make sure you’re using the correct valve for your rim and then insert it.
Put the entire inner tube inside the tire so that it fits inside the rim.
Take care not to pinch the inner tube when installing it.

Installing the tire

Start installing the tire at the valve.
Finish installing the tire across from the valve to avoid pinching the inner tube.
Never install your tire with a tool or a tire lever, as you risk pinching or puncturing the inner tube.

Inflating the tire

Carefully inflate your tire 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.

Pro tip

To avoid punctures from pinching and for the best tire performance, we recommend checking your tires and inflating them to the suggested pressure before every ride.

Bought 4 of those and all of them failed during or shortly after installation without me being able to do a single km on my bike.
Response of the brand

Hi Bernd,


I'm really sorry to hear about your dissatisfactory experience. Certainly you should not be experiencing any problems with the tube upon proper installation.


There are 2 quite common causes when tubes burst upon installation:


Tyre bead not seated fully

This is more common in wire bead tyres, when the bead is not seated fully, the tube can 'peek' out of that gap and burst during installation. Here's a great video that shows how it can happen. A clue is to look at how the tube burst - these kind of bursts tend to be quite big and the tube would be shredded near the point of explosion, just like in the video link above.


Rim tape slipped, twisted or damaged

On your bicycle rim bed (on the inside) there are holes to allow the spoke & nipple to be inserted during the construction of the wheel. These holes are normally covered with a rim strip to prevent the tube from inflating into those holes and bursting. Even if the rim is single-wall, the rim strips still protect the tube from the sharp edges of the spoke/nipple. It is possible for the rim tape to slip or be damaged, exposing the hole (double-wall rim) or spoke/nipple (single-wall rim). When tubes burst this way, the puncture is usually relatively small and on the section of tube facing inside - here's a picture showing how it might look like.


Otherwise, we are happy to refund or exchange the tube for a new one, for which you may contact our User Happiness Centre in Singapore Lab here :)

Good value tube for MTB
Jesser (Singapore)
This inner tubing is thin and it burst during installation. So dangerous. Although i do not expect it to be the best quality upon this price but i do not expect it 'explode' is such a way. Dangerous item.
