NOTICE FOR INSTALLATION: 1. TPU inner tubes must never be used with rim brakes. Excessive heat exposure can lead to air pressure loss. 2. Use appropriate rim tape to protect the TPU inner tube, otherwise it may get damaged. 3. Never inflate the TPU inner tube over 0.3 bar during installation. Over-inflating at this stage can over-stretch the inner tube and make it unusable. 4. Ensure the rim valve hole diameter is correct. If the valve hole is too large, the valve can twist or be cut off. 5. Pay attention to inner tube installation. Always ensure the inner tube or valve is not stuck, twisted, or damaged. 6. TPU inner tubes should never be reused with a smaller tire! When installing a smaller tire, a new tube must be used.
