Even lighter, even more compact, ideal as a spare inner tube, the S-Tubo-MTB range of products from Tubolito has been developed to have the smallest possible packaging size. With a removable valve body, the inner tubes have a size of only Ø 3.5 x 5 cm high when packed. The puncture resistance is the same as for standard butyl rubber inner tubes, with a weight of only 45g (size 29 ").
