YunSCM 700 23c best choice for 60mm Presta valve high bicycle suitable for road bikes 2-pack, thick-walled tubes, rims, 700x18/25c tubes,

✅【700x18-25c Bicycle Tube】: Applicable to 700x18c/20c/23c/25c bicycles, Presta valve long valve 60mm, best choice for high rims. Suitable for most road bikes and mountain bikes. Note: Please check your tire size before purchasing. Tire size is usually indicated on the outer tire. ✅【Space-saving and easy to carry】: The 700x18c tube folds up to be very compact, so you can carry it with you when you go out for long-distance cycling and avoid the awkward situation of being unable to ride your bike due to a flat tube. ✅【New Thickened Design】: To meet the needs of customers who frequently ride bicycles on a daily basis and to further enhance the durability of the tube, we have developed a reinforced tube that is approximately 25% thicker than the standard version, with a noticeable increase in thickness. This improves the tube's explosion resistance and puncture resistance. ✅【700x18-25c High-Quality Butyl Rubber】: This material provides better airtightness, can retain air for a long time, and does not require constant inflation. ✅【Budget Saving】: Doing it yourself will save you money compared to going to a local shop to change your tires. It can also serve as a spare tube, preventing the awkward situation of being unable to ride after a tube bursts. ✅【Correct Installation Method】: First, push the tube into the rim and inflate it with a small amount of air (20%). Next, mount the tire, making sure the edges of the tire and rim are aligned and the tube is not pinched, then inflate the tube to the correct pressure again. (Please note that 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 rim, air leaks or punctures may occur.) Suitable for 700mm wheels. Tire width: 18-25mm. The product includes: 2 x 700X18/25C bicycle inner tubes.
