Sisäkumi 26" Vittoria Standard AV 48mm (26x1.5/2.0 - 40/50-559)

When you ride daily, reliable utility means everything, and no inner tube handles the grind like butyl. It retains air across multiple days and its more rugged qualities mean it can be tossed around in a jersey pocket or saddlebag and installed on the side of the road or trail. High air retention, easy mounting, reliable puncture resistance, and a 0.9 mm tube wall – butyl inner tubes define the reliable convenience of clinchers.
