The R'Air features a latex-butyl composition for the ultimate in ride quality and durability, seamless construction, and threaded valve stem. The total weight is a scant 84 grams for an 80mm valve length model. Who could ask for more in a tube?

When it comes to fabricating tubes, no one does it better than Panaracer. They are not outsourced to another manufacturer, but made in the Panaracer factory under the direct supervision of the engineering and production staff. Beyond controlling the production environment, every single tube is tested prior to being boxed and shipped for quality assurance. The threaded stem will prevent rattling and can be used with extension-style valve extenders. The R'Air has many benefits over standard tubes. The easiest way to understand what the R'Air is all about is to define it by construction and material.

The R'Air features a consistent wall thickness throughout the entire diameter of the tube and a completely seamless construction. This unique combination allows the tube to roll perfectly round without hops or dead spots. The Air Flex Lite Butyl material used in the tube is simply amazing. This proprietary compound is a mix of butyl and latex which rides and feels like a latex tube but is robust and holds air like butyl. The Air Flex Lite is super-flexible and has an exceptional strength to weight ratio and is very light. Now you can have the best of both worlds, reliability of butyl with the sublime ride quality of latex.

The price of this tube reflects the quality of the tube and the ride quality that the tube produces. In summary, the R'Air will save approximately 20 grams in rolling weight over a standard butyl tube and improve reliability and enhance ride quality due to the weight reduction, thoughtful construction and Air Flex Lite material. It is simply the best tube ever made.

Please note that the valve core is NOT removable.
