I do about 15,000 km a year. I have a comment about this product. Very poor manufacturing quality, especially at the joint, which can also be seen in the attached picture. Due to the deformed shape of the inner tube, the bicycle tire is also of a changed shape. As a result, vibration occurs at higher speeds, which is higher at higher speeds. The feeling is unpleasant and safety is also at risk. I wrote a complaint to the seller and attached this picture. However, the seller rejected the complaint and asked me to attach a video of how the bike vibrates at higher speeds. But I don't know how to record a video on which it will be seen how the bike vibrates, at a speed higher than 40 km per hour? I do not recommend buying this product.
