Dunlop adds another chapter to the CX 400! Like the previous generation, this 10.7-ounce racquet provides intermediate players with a crisp, lively and spin-friendly hitting experience. For 2021, Dunlop adds FlexBooster technology, a thin rubber material in the shaft that absorbs harsh vibrations without compromising your connection to the ball. As with the previous generation, this racquet's upper hoop is softened with Sonic Core, a material technology that uses Infinergy to minimize shock and transfer greater energy to the ball. This stick also features a PowerGrid StringTech system, which optimizes string spacing to create a more comfortable, spin-friendly and responsive hitting experience. Improve your game with the Cx 400 TOUR’s fusion of power, control and spin. So you can generate easy power.
