We have developed a thick reinforced tube that feels thick. The tube's explosion resistance and puncture prevention performance have been improved. ✅【High Quality Butyl Rubber】: This material bicycle tube 700 38c can provide better airtightness and retain air for a long time, so you don't have to hit the air all the time. ✅【Budget Savings】: Doing it yourself will save your budget than going to the local store to replace your tires. 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. (If the tube and tire are not inflated together, i.e. if only the tube is inflated, or if the tube is pinched between the tire and the edge of the rim, air leaks and punctures may occur. Please note that it may become easier.) Suitable for 700mm wheels. Tire width is 35~43mm. (Tires common to the 700X35c-700X43c section) The product is 2 bicycle tubes.

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. Insert the tube evenly into the tire with a small amount of air filling (less than 10%), stack the carcass in order and do not fold it inside the tire (folding and inflating it is easy to puncture), the tube and tire together over the steel ring, and inspect whether the lower tire is completely packed into the tire, and there should be no small step between the tire and the steel ring. You can then start aerating the tube. Installation is complete.
