A new system has been developed to eliminate the need of air in bike tires, while still preventing the common occurrence of punctures, tube replacements, even pressure checks.Instead of air, it uses rubber stretched over a series of carbon nano tube reinforced composite rods to provide its cushioning. these rods can be adjusted, changing the tension of the rubber to suit different types of terrain, improves flexing and recoil cycling.
