The adidas Challenge Speed is a blade for modern top players who demand high levels of power and superb balance at the same time. The Challenge Speed is based on a classic 7-ply construction. The result is a thinner blade which maintains speed. The enhanced feeling and reduced weight are additional advantages of the thinner construction. Although the Challenge Speed is a very powerful blade, its stability and soft feeling on the surface make it very easy to use. If you are an offensive player who wants to add power to the topspin while keeping the natural feeling of an all-wood blade the adidas Challenge Speed should be your first choice!
