The racket features a redesigned mold and incorporates the key innovations of the new AT10 Collection: the Weight Balance system, which allows you to adjust the balance to suit your playing style; the responsive Chromic Paint finish; and the Dual Spin surface for maximum spin. This model utilizes the new 12K Alum Xtrem carbon, which offers a stiffer ball feel, increased durability, and consistent performance, even in extreme temperature variations.
