For trials unicyles with 19 rims, a boxed Schwalbe 20” x 2.10 - 3.00 Inner Tube with a reinforced rubber valve base, a 40mm Auto Valve, weighing 200g.
Reliability - each tube is inflated at the Schwalbe factory for 24 hours and tested for leaks.
Air Retention - Schwalbe use a very high butyl content and a very high material purity to ensure their tubes retain air pressure considerably longer than other tubes.
Recycling - every Tube is 100% recycleable and without any loss of quality Schwalbe use recycled material in the production of their new tubes. They have developed in their own factory a special devulcanization process which for several years has proved very successful. Every Schwalbe standard tube is made up of 20% recycled old tubes. Taking into account all transport routes, the energy balance is positive - just a fifth of the energy is used in comparison with the production of new butyl!
