Isometric
The square-shaped ISOMETRIC frame shape is designed to keep vertical strings at a similar length, as well as the horizontal strings to produce an expanded sweet spot in all directions.
Aero-box Frame
Aerodynamic contouring of the top of the frame minimizes air resistance so air flows faster across the curved surface during the swing, accelerating the head speed and transferring more speed and power into hits. this construction tapers into the YONEX Box Shape midway through the frame for high stability, low-torque performance, and more accuracy
Built-in T-joint
Moulded deep into the layers of graphite where the frame connects with the shaft, the YONEX Builte in T-Joint creates a durable and high-strength one-piece frame that is torque-free.
