energy return wheel - airless bicycle tires by britek
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. the 'energy return wheel' concept by
colorado-based designer brian russell demonstrates the possibilities of advanced wheel technologies.
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. with the intention of reducing weight, a 29er wheel made from carbon
fiber is incorporated. further improvements include the possibilities of implementing a thin sidewall to keep
mud and trail debris out for a more consistent ride.
