Choosing an inner tube:
To keep your bike properly maintained, it's essential to know the exact dimensions of your tyres.You'll find this information on the tyre sidewall (diameter and cross-section).For example, 700 x 35 means your tyre is 700 mm in diameter and 35 mm wide.
On the tyre sidewall you will also find the dimensions in mm in ETRTO international units.
For example: 35-622 means your tyre is 35 mm wide with an inner diameter of 700 mm (so 700 x 35)
Inflating a tyre:
The ideal pressure is shown on the sidewall.As you inflate, check that the tyre is settling into place evenly.
How to change an inner tube
For error-free installation:watch the video, inflate to 0.2 bar, insert the valve, place the inner tube inside the tyre, then in the rim, all this nice and gently.
Pro advice:
To prevent any risk of puncture by pinching, systematically check the tyre pressure efore each ride.
To remove your inner tube, the tools you'll need are:
Effortlessly remove your inner tube using our B’TWIN tyre levers.

What to check before installing your inner tube:
Before pumping, make sure nothing's rubbing against the tyre, that the rim strip is smooth and correctly positioned, and that the rim has no sharp parts or deformations.
Fitting a tyre:
No tool to mount your tyre:start at the valve and finish by hand, on the opposite side.
