Description
This inner tube allows you to keep riding in conditions where a standard tube would have burst. How to choose an inner tube: To properly maintain your bicycle, it is important to know the exact dimensions of your tyres. This information can be found on the tyre sidewall (diameter and section). For example, 29 x 1.90 means it is a tyre with a 29-inch diameter and a 1.90-inch width. On the tyre sidewall you will also find the dimensions in mm of the international ETRTO unit. For example, 50-622 means it is a tyre 50 mm wide by 622 mm in inner diameter (i.e. approx. 29 x 1.90). To remove the inner tube, you will need the following tools: Easily remove your inner tube with our B’TWIN tyre lever. Checks before fitting the inner tube: Good installation always starts with a prior check: clean tyre, crack-free rim tape, defect-free rim. How to change an inner tube? Check out our tutorial. Light inflation prevents mistakes. Position the valve, install the tube in the tyre, push it inside the rim without pinching the tube. Tyre mounting: A well-done mounting starts at the valve and ends at the opposite end, without tyre levers to prevent punctures. Tyre inflation: Before inflating, check the pressure in PSI or bar. While inflating, check that the tyre is properly seated. Pro tip: To avoid any pinch flats and get the best performance from your tyre, we advise you to check and adjust your tyre pressure before each ride.
