Vittoria’s Ultra Light Speed inner tubes are made with thermoplastic polyurethane. This material is recyclable and offers excellent technical characteristics, withstanding temperatures from -47°C to +100°C. It can be extruded in very thin thicknesses, providing good elasticity and airtightness for consistent air pressure over time. The tubes are resistant to punctures, and in the event of a puncture, the air release is slower than butyl or latex, enhancing safety. Achieving an incredible 30g lightness and higher puncture resistance than butyl tubes, Ultra Light Speed utilizes multi-layer co-extrusion technology and is only 0.35mm thick, significantly thinner than standard 1mm butyl inner tubes. High-frequency technology is used for welding. Their compact dimensions make them easy to carry, and they fit perfectly for cycling enthusiasts. This specific inner tube is designed for 700x25/30 tires and features a 60mm Presta valve (RVC).
