The nominal wheel size (e.g., 14 inches) alone is not sufficient. Always check the full size marking on the sidewall of your current tyre, which should match the \"14 x 2.125\" specification of this inner tube. Additionally, confirm that the curved 90°\/60° valve angle is compatible with your rim's valve hole and overall wheel design.\u003c\/p\u003e\n\u003cp\u003eThe inner tube has an outer diameter of approximately 333mm and an inner diameter of 265mm when uninflated. The valve stem length is approximately 25mm from the tube surface to the tip of the valve. The net weight of the inner tube is approximately 139.4g.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation and Safety Guidance\u003c\/h3\u003e\n\u003cp\u003eProper installation is essential for the longevity and safety of your inner tube.
