This inner tube allows you to continue cycling when a conventional inner tube would have gone flat.
20" self-repairing inner tube. The preventative liquid inside the inner tube instantly repairs punctures.
This inner tube allows you to continue cycling when a conventional inner tube would have gone flat.
To maintain your bike properly, it's important to know the exact dimensions of your tyres.This information appears on the tyre sidewall (diameter and width).For example, 20 x 2.00 means your tyre is 20 inches in diameter and 2.00 inches wide. On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-406 means that the tyre is 50 mm wide and has an inside diameter of 406 mm (i.e. 20 x 2.00).
Use B'TWIN tyre changers to remove the old inner tube.
To avoid repeated punctures, carefully inspect the tyre, rim tape and rim each time you change.
Before installing your inner tube, watch our video, inflate it slightly, insert the valve, fit it properly into the tyre and then into the rim.
Start mounting the tyre at the valve. Finish mounting the tyre opposite the valve to avoid pinching the inner tube. Never mount your tyre with a tool or a tyre lever, as you risk pinching and puncturing the inner tube.
Before inflating, mark the recommended values on the tyre sidewall.All the while, make sure it's properly positioned.
Tyre pressure must be adjusted before each outing to avoid punctures caused by pinching.
