The inner tube is a sealed airbag and cannot withstand significant pressure. The pressure of the inner tube relies on the outer tube.</span></p><p><span style="font-size: 16px; font-family: Verdana;">Almost all inner tubes, once inflated to a certain extent, will exhibit uneven thickness. So first, after installing the inner and outer tubes, inflating the inner tube (which cannot be inflated separately) is the correct method of use.</span></p><p><span style="font-size: 16px; font-family: Verdana;">Before purchasing an inner tube, please check whether the original inner tube is an American valve or a French valve, and its size, so that it can not be installed after purchase.</span></p><p><span style="font-size: 16px; font-family: Verdana;">Brand: CST</span></p><p><span style="font-size: 16px; font-family: Verdana;">Material: High quality butyl rubber</span></p><p><span style="font-size: 16px; font-family: Verdana;">Model number: 27.5 inches</span></p><p><span style="font-size: 16px; font-family: Verdana;">Air mouth: American valve, French valve</span></p><p><span style="font-size: 16px; font-family: Verdana;">Valve valve length: 32mm 48mm</span></p><p><span style="font-size: 16px; font-family: Verdana;">Product configuration: color box packaging</span></p><p><span style="font-size: 16px; font-family: Verdana;">Package include:1pcs</span></p><p><span style="font-size: 16px; font-family: Verdana;">Note: 1.
