---------------------------------------------------------------------- 【Cautions for using electrical products】 When using electrical appliances, please note that the voltage is different from that of Japan, which may cause malfunctions. Since the plug type is Japan type(A or B type), please check the voltage and use a transformer. Please note that a transformer is different from a conversion adapter. We are not responsible for malfunctions caused by use without a transformer.

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- This Gravel TPU inner tube fits a range of sizes: 28" (700c), 700x32c-40c, and 29x1.5-1.75 for MTB. Lightweight Valve Stems: Metallic threads are used to reduce weight for cyclists. Replacing plastic valve stems with metallic threads significantly extends their service life, allowing them to last longer than plastic valve stems. Meanwhile, TPU inner tubes weigh just 40g each and are more durable. [Ideal replacement for spare tire] Approximately 70% smaller than conventional butyl rubber inner tubes, it can be easily taken out as a spare tire by simply putting it in your pocket or bag while riding. 【Excellent Puncture Resistance】TPU material promises cyclists to own a more sturdy inner tube, greatly reducing the chances of punctures and keeping your cycling journey uninterrupted and happy 【Easy Installation】We have redesigned the valve stem length specifically based on market research and surveys. We found that many valve stems have problems with hard installation. In that case, we offer 65mm and 85mm lengths for your choice. These new designs make our TPU inner tubes easier to install than other regular standard TPU tubes and more comfortable for your hands during assembly and disassembly.
