The smallest and lightest bicycle tube in the world, S-Tube is designed for those who value performance above everything else.
S-Tubo's tiny size makes it the ideal spare tube on your rides. Due to a removable valve, S-Tubos can be rolled up to an extremely small size (Ø 3.5 x 5cm). Despite a very light weight of only 45g (29''), S-Tubos are as good as standard butyl tubes against punctures.
Great as a spare tube for riders using a tubeless system.
