Design details
How to choose an inner tube:
To take good care of your bike, it's important to know the exact dimensions of your tyres.This information is given on the tyre sidewall (diameter and cross-section).
For example, 20 x 2.10 means that the tyre is 20 inches in diameter and 2.10 inches wide.
On the tyre sidewall you will also find the dimensions in mm in ETRTO international units.
For example, 50-406 means a tyre that is 50mm wide and has an inner diameter of 406mm (approx. 20 x 2.00).
Here are the tools you'll need to remove the inner tube:
With B'TWIN tyre levers, it's easy to take off your inner tube.
Checks to carry out before installing an inner tube:
Even a tiny fissure in the rim strip can cause a slow leak.Inspect each element before mounting.
How to change an inner tube:
For successful mounting, start by watching our video.Slightly inflate the inner tube, insert the valve, put the inner tube correctly in place and make sure the rim isn't pinching it.
Fitting a tyre:
The correct mounting method is to start at the valve and finish at the opposite side, without using tyre levers so as not to risk a puncture.
Inflating a tyre:
Adhere to the manufacturer's recommended pressure, marked on the sidewall.While inflating, check that the tyre remains evenly positioned on the rim.
The professional's advice
Before each use, take a moment to check your tyre pressure and reduce the risk of puncture.
