[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. We have developed a thickened tube with a visible thickness.

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.
