The ultra light, extra durable bicycle tube. 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.Lightweight:- 2/3 lighter than 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.Developed:- The tubolito inner tube and all assembly parts are sourced. This has some major advantages. We can maintain very high quality standards. We can realize fast innovations by having a short feedback loop between development and production site. We can maintain sustainability trough to short transport routes.Tubo CX-Gravel:- Tubo-CX/Gravel All tubes are the ideal spare tube for all 700c and 650B tires from 30 mm-47 mm width. However, it is not only a savior in need but can be perfectly used on a daily basis as it still is as robust as standard rubber tubes. Also leftovers of tubeless liquids do not do any harm to it.Features:- Ideal spare tube through small packed size- Easy mounting- Perfect CX/Gravel spare tube- Can also be used as daily driver- Compatible with disk brakes- Same strength as a standard tube- Low rolling resistance- Perfect spare tube for tubeless setups Specifications:- Diameter: 700C- Weight: +- 60 g- Tyre width: 32-50 mm- Valve: Presta 42 mm
