[New release thickness 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 20 2.40 tube, it is approximately 25% thicker than the regular version tube, making it thicker than the naked eye.

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.
