The Ultra Light Speed tubes from Vittoria are made from thermoplastic polyurethane. The material is fully recyclable. It is 70% lighter than a standard tube. The material has good elasticity and is absolutely airtight, allowing the air pressure inside to be maintained at a constant level for a long time. It is resistant to punctures, and in the event of a puncture, the airflow is slower compared to butyl and latex, resulting in increased safety.
