YAMAHA INPRES DRIVESTAR TYPE/S Irons (Single) with SPEEDER NX for Yamaha M-425i Carbon Shafts (2025mm) [Clearance Price]

Going beyond the distance with 3-Point Resonance Technology, which maximizes repulsion efficiency. Conventional irons, due to their design, have a "center of gravity" (the area of the face that flexes the most) far from the "center of gravity" and the actual "point of impact," making it difficult to maximize distance. By placing a rib on the toe side of the iron head, Yamaha has succeeded in moving the "center of gravity" closer to the "center of gravity" and "point of impact," thereby maximizing repulsion efficiency. ■ Improved initial velocity performance at the impact point. The new "X37" material, with its high strength and toughness, is used to achieve a precision one-piece casting with a sole thickness of just 1.1mm. The repulsion area of the sole has been expanded compared to the previous model, resulting in increased sole flex, dramatically improving repulsion performance, especially in the lower part of the face closest to the point of impact. ■ Achieve overwhelming distance with a high trajectory. A large-capacity tungsten weight is placed behind the sole (TYPE/S: 77g). The ultra-deep and low center of gravity delivers impressive distance and a high trajectory.
