Description
Inner tube suitable for 29-inch diameter tyres, section from 1.90 to 2.50 with 48 mm Schrader valve. How to choose an inner tube: For proper maintenance of your bicycle, it is important to know the exact dimensions of the tyres. This information is indicated on the tyre sidewall (diameter and section). For example, 29 x 1.90 indicates a tyre with a 29-inch diameter and 1.90-inch width. On the tyre sidewall, you will also find the dimensions in mm of the international ETRTO standard. For example, 50-622 means it is a tyre 50 mm wide by 622 mm inner diameter (i.e., 29 x 2.00). To remove the inner tube, you will need the following tools: B’TWIN tyre levers make it easier to remove the damaged inner tube. Checks before installing the inner tube: A cracked rim tape, even slightly, can cause frequent punctures. The slightest defect in the rim tape can compromise the safety of your wheel. A damaged rim tape is a common cause of invisible punctures. Always replace a damaged rim tape: it is a low-cost part, but has a high impact. Choose a preventive replacement instead of an improvised repair. How to change an inner tube? First of all, watch our tutorial. Inflate the inner tube to low pressure, insert the valve, align the tube correctly in the tyre and be careful not to pinch it during assembly. Tyre assembly: To avoid any pinching, mount your tyre by hand, starting at the valve and finishing on the opposite side. No tools are required. Tyre inflation: Before inflating, check the recommended pressure on the sidewall. During inflation, observe that the tyre is well seated on the rim. Professional tip: Check your tyre pressure before every ride: this reduces punctures and improves your riding comfort.
