Even lighter and more compact: the perfect spare tube. S-Tubo-MTB's can be rolled up to an extremely space saving size (Ø 3.5 x 5 cm). Despite a very light overall weight of only 45 g (29) they are as puncture resistant as standard butyl tubes for everyday riding and are also perfect to use as a spare tube for riders using a tubeless system. Ready for disc brakes.The main difference between Tubo and S-Tubo is the wall thickness. Tubo products have a thickness of 0,3 mm, while S-Tubo products only have a thickness of 0,15 mm. For comparison a sheet paper usually has a thickness of 0,1 mm.These differences entail different characteristics: Tubo products are twice as robust against punctures as standard tubber tubes. While S-Tubo products are sill as robust agains punctures as standard rubber tubes, they convince through smallest packed size, they convince through smallest packed size, low rolling resistance and low weight.For a long time, the innertube has been overlooked in the bicycle industry. We will change that. Our vision the perfect innertube - street, trail or city developed for the optimal cycling experience.Features:Lightweight:- Lighter as a standard tube- Every gram counts, when it is up to cycling fun. Even more if you reduce the rotational weight.- Tubolito offers an easy and achievable weight tuning.- We can provide this solution, as we are combining a new material with a self-developed production technology. Applying this technology allows us to build an innertube that weighs only 45 grams at our S-Tubo productTough:- 2 times stronger than standard tubes- Lighter and more robust. We make the impossible possible.- We can solve this contradiction by using a new concept:- We are manufacturing the Innertube with a thermoplastic elastomer, called TPU. This group of materials is known for its durability and excellent damping abilities. It has replaced many rubber products in the automotive and pharma industry already.- It was our goal to transform the excellent material characteristics into an outstanding bicycle product. We achieved that by reducing the number of contact areas and kept the seams to a minimum.Specifications:- Diameter: 27.5/29- Weight: +- 43 g- Tyre Width: 1,8´´-2,5´´- Valve: Presta 42 mm
