With two contrasting racquet profiles built into one frame, the DUORA is designed to bring an all-around blend of power, speed, and control to a player's game. Combining technology that enhances both forehand and backhand swings, the DUAL OPTIMUM SYSTEM remains sleek in design. Constructed with NANOMETRIC DR*, a lightweight graphite material weighing 60% less than conventional graphite, the DUORA offers players unparalleled swing speed, firmer shuttle hold, and enhanced repulsion for explosive shots.

Dual Optimum System:
Two contrasting racquet profiles in one unique Dual Dynamic Design allow players to enhance both their forehand and backhand. Command the court with powerful forehands and speedy backhands.
NANOMETRIC DR is an enhanced graphite based on unique NANOSCIENCE technology for a firm shuttle hold creating maximum repulsion. * NANOMETRIC is a material which applies the NANOALLOY™ technology of Toray Industries, Inc.
DUORA GROMMET DESIGN:
8 linked grommets made with differing thicknesses on either side of the frame. The stiffer AERO side grommets pull the string harder for increased power.
