Nano-Powered by Fullerene for more repulsion and speed from a compact swing.Traditional racket constructions increase the thickness of graphite or carbon fibre layers for high strength, which adds weight to the frame and makes a racket difficult to manoeuvre.The Yonex nano – structure uses nano – sized particles of fullerene and carbon. This process gives a high performance molecular bond which allows the head of the racket to be lighter yet stronger. The result is a very fast head speed creating maximum power.30% More Impact Resistant10% More Durability5% More PowerFlex: StiffWeight: 85-89gFrame Composition: Graphite & Nano CarbonShaft Composition: H.M.
