Choosing an inner tube:
To maintain your bike properly, it's important to know the exact dimensions of your tyres. This information appears on the tyre sidewall (diameter and width).For example, 27.5x1.90 means that the tyre is 27.5 inches in diameter and 1.90 inches wide.
On the tyre sidewall you will also find the dimensions in mm in ETRTO international units.
For example, 50-584 means your tyre is 50 mm wide with an inner diameter of 584 mm (27.5 x 2.00).
To remove your inner tube, the tools you'll need are:
Use B'TWIN tyre changers to remove your used inner tube.
Checks to make before installing an inner tube:
A poorly maintained rim or a tired rim base can ruin your new inner tube.Check carefully.
How to change an inner tube
To make it easier to set up, start by our video.Inflate slightly, insert the valve, install the inner tube securely and make sure it is not pinched in the rim.
Fitting a tyre:
Start mounting the tyre at the valve.
Finish mounting the tyre opposite the valve to avoid pinching the inner tube.
Never mount your tyre with a tool or a tyre lever, as you risk pinching and puncturing the inner tube.
Inflating a tyre:
Proper fitting starts at the valve and ends at the opposite end, without the need for a tyre lever to prevent punctures.
Pro advice:
Simple maintenance:adjust tyre pressure before each outing to avoid problems.
