Extremely lightweight Tubolito Road inner tubes are developed to keep weight as low as possible, making them the most efficient and cost-effective way to reduce wheel weight and spoke rotational mass. In addition, they are twice as resistant to punctures as standard tubes.Weight 38g - 40g depending on the length of the valve Version with 42mm galus valves. 60mm or 80mm The resistance of the Tubolito is 4.6W lower at 28.8 km/h than a standard tube It holds air like a standard tube For tires 18 to 28mm wide The Tubolito can be temporarily inflated with CO2, but it is recommended to deflate it immediately after finishing and inflate it with air conventionalInstallation in the rim must be done with Tubolito inflated to 0.2-0.5 bar. Inflate to this value on the outside of the rim, making sure the valve is facing inward to avoid unnecessary stress on the material.
