The new material Cup-Stack Carbon Nanotube is applied in the racquet frame which enables to give the players right amount of flex to stay with the ball, and quick repulsion to make the full energy available for power return.

Flexible and Durable
If these composites using CNTs of various characteristics can make these rackets so good - just think what they can (and will?) do for automobile frames and bodies - strength, flexibility and durability at reduced weight and cost, more than likely.
