The inner tubes Vittoria Ultra Light Speed are made for pure speed. Designed to offer the lowest rolling resistance possible, ULS are the fastest and lightest tubes ever developed by Vittoria. They are 70% lighter and 14% faster than standard butyl tubes.

They are made of thermoplastic polyurethane (TPU), which offers lower rolling resistance and lightweight compared to standard butyl inner tubes. 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. It has a good elasticity and it is completely airtight, which allows keeping constant air pressure inside for long time. It is resistant to punctures and in case of puncture, the flow of air is slower compared to butyl and latex, which translates to increased safety. 

In order to reach the incredible 30g lightness and a higher puncture resistance than butyl tubes, Ultra Light Speed are made with the multi-layer co-extrusion technology and are 0,35mm thick. They are extremely thin if compared to butyl inner tubes, which usually are 1mm thick. The welding is performed with high frequency technology. By using Ultra Light Speed tubes in both tires, you can save up to 160 g. That’s why Ultra Light Speed are the perfect choice for road cyclists that want the highest speed without giving up the practicality and ease of use of a tube tire set-up.

The Ultra Light Speed tubes feature a red, Vittoria-branded, extensible valve with removable core. The packaging also contains a repairing patch and a cleaning cloth. Made in Germany, the TPU material of Ultra Light Speed tubes is 100% recyclable – the valve must be cut off from the tube before disposal.
