Vittoria's Ultra-Light Speed Inner Tubes: Engineered for Racing on Disc Brake Wheels.
Vittoria's ultra-light speed inner tubes are made with thermoplastic polyurethane (TPU). Besides being completely recyclable, this material offers excellent technical characteristics; it is steady from -47°C up to +100°C. It can be consistently extruded in very thin thicknesses.
TPU has good elasticity and is completely airtight, which allows for constant air pressure inside for a long time. It is resistant to punctures, and in case of a puncture, the flow of air is slower compared to butyl and latex, which translates to increased safety.
To reach their incredible 30g lightness and a higher puncture resistance than butyl tubes, these ultra-light speed tubes are made with multi-layer co-extrusion technology and are 0.35mm thick. They are extremely thin if compared to butyl inner tubes, which are usually 1mm thick. The welding is performed with high-frequency technology.
Due to its ultralight, extremely supple qualities, TPU requires special care when mounting. Please see the installation and inflation instructions included with the tube. These inner tubes are only suitable for use with disc brake wheels.
