I remember reading this some moons ago, but it's reappeared in this months (May) Cycling Plus: 'Hutchinson has developed a tyre which uses no air at all. The Serenity Airless Tyre employs composite materials and layers of rubber..to keep the tyre's shape and provide shock absorption and it could be in bike shops in 2010. Anyone making puncture repair kits must be getting nervous'. Wos reckon - answer to a maiden's prayers or a false dawn??
