Thank you for viewing. In a word, this racket is a full-fledged racket for stroke players (rear court players) who pursue "overwhelming repulsion" and "speed shots." Main features and performance Sharpness of 'Bounce': The biggest feature of the 'Nano Force' series is its ability to powerfully bounce the ball back. It is easy to hit sharp speed balls even with little force, and it is particularly suitable for players who want to attack with shoot balls (straight, fast balls). Excellent face stability: Rather than the "flex" of a single shaft, the lack of face deflection stands out. Even when you miss the sweet spot, control is less likely to be disrupted, enabling stable full-power shots. Isometric shape: Yonex's unique square frame shape provides a wider sweet spot (effective hitting area) than conventional round rackets. Detailed specifications Target: Intermediate and advanced stroke players. Face Size: 85 square inches (slightly smaller than the current mainstream, requiring more precise hitting). Materials: State-of-the-art materials of the time, such as high-strength carbon, fullerene, gum metal, and 3D graphite, are luxuriously used. It is currently discontinued and difficult to obtain new, but it is a rare model that still has strong popularity in the used market due to its refreshing hitting feel.
