Inner tube / tire size 20x1.5/1.9 inches with schrader valve

This inner tube is suitable for tires with a width of 1.50 to 1.90 and a diameter of 20, with a 33mm Schrader valve.

How to choose an inner tube:

To properly maintain your bike, it's important to know the exact dimensions of your tires. This information can be found on the tire's sidewall (diameter and section). For example, 20 x 1.60 means a tire with a diameter of 20 inches and a width of 1.60 inches. On the sidewall, you will also find the dimensions in millimeters using the international ETRTO unit. For example, 40-406 means a tire with a width of 40 mm and an inner diameter of 406 mm (i.e., 20 x 1.60 x 20 x 1.60).

To remove your inner tube, the tools you will need are:

An essential tool for inner tube removal: tire levers from B'Twin.

Checks to perform before installing the inner tube:

Make sure the rim strip covers all the spoke holes. A cracked or misaligned rim strip can damage the inner tube. The rim strip should be centered, clean, and in good condition. Replace the rim strip if it is cracked, stiff, or worn. A new rim strip effectively protects the inner tube from being pressed against the spokes. Use the correct rim strip for the rim's width and diameter. A good rim tape prevents internal punctures caused by spoke heads.

How to change an inner tube:

Follow our video guide before you begin. Having a small amount of air pressure in the inner tube will prevent pinching. Insert the valve, properly place the inner tube into the tire, and then into the rim.

Tire installation:

Start from the valve and work your way to the other side. Do not force the tire with a tire lever to avoid the risk of punctures.

Inflating the tire:

The ideal pressure is indicated on the tire's sidewall. Carefully inflate the tire and ensure it remains in its correct position.

Expert tip:

Inflate your tires before each ride to reduce the risk of punctures and achieve more efficient riding.
