[700X18-32C Bicycle Tube]: Applicable to 700x18c/25c/28c/30c/32c bicycles, Presta valve 48mm. Suitable for road bikes and cross bikes. Note: Please check the tire size before purchasing. Tire size is usually displayed on the side of the outside tire. [Does not take up much space and is convenient to carry]: The 700 28c tube has a small volume when folded, so you can carry it with you when you go out and run long distances, and avoid the awkward feeling of not being able to ride after the tube gets punctured. [New product release, thick design]: In order to meet the needs of customers who often ride bicycles on a daily basis and to further increase the durability of the tube, we have developed a thicker tube that is approximately 25% thicker than the regular tube and has a thickness that can be seen with the naked eye. The tube's explosion resistance and puncture prevention performance have been improved. [High Quality Butyl Rubber]: This material's 700 25c tube can provide better airtightness and retain air for a long time, so you don't need to blow air all the time. 【Budget Savings】: Doing it yourself will save your budget than going to the local store to replace the tire. As a spare bicycle tube, you can avoid the awkward feeling of not being able to ride after the tube bursts. ✅【Correct installation method】: First, push the tube into the rim to let a small amount (20%) of air into the tube. Next, install the tire, make sure the edges of the tire and rim are aligned and the tube is not pinched, and then re-inflate the tube to the correct air pressure. (Please note that if the tube and tire are not inflated together, that is, if only the tube is inflated, or if the tube is sandwiched between the tire and the rim, air leaks and punctures may occur more easily.) Suitable for wheel diameter 700mm. Tire width is 18~32mm. (Tires common to the 700X18c-700X32c section) The product includes 6 bicycle tubes, 2 rim tapes, and 3 tire levers.

Warm tips for installing tires and tubes: 1. The rolling direction of a tire is the mounting direction of the tire (some tires are marked with an arrow, and the direction of the arrow is the rolling direction of the tire). Clean the inside and outside of the tire to prevent the presence of foreign substances such as gravel and impurities, and install the tire according to its rolling direction. 2. After installation, inspect whether the bead (tire edge) is uniformly symmetrical, the bead must be outside the bead in all places and parallel to the bead in all places. Otherwise, there will be blurring when driving. 3. The tube should be evenly inserted into the tire with a small amount of air filling (less than 10%), the carcass should be stacked in order and not folded inside the tire (folding and inflating it is easy to puncture), the tube and tire should be put together on the steel ring, and inspect whether the lower tire is all packed into the tire, and there should be no small steps between the tire and the steel ring. You can then start aerating the tube. Installation is complete.
