A Extended version of the Pro Kennex Ki Q+5 Pro, the Pro Kennex Ki Q+5X Pro features arm-friendly technology that can help or alleviate player’s tennis elbow. With multiple groundbreaking technologies, the Pro Kennex Ki Q+5X Pro has added power and spin to the already outstanding comfort benefits the brand is known for. By segmenting the Kinetic Moveable Mass and placing it into the four corners of the racquet head, Quadfocused design increases the frame’s torsional stability even further, moving the sweet spot higher in the string face (as the mass of the frame moves higher, the sweet spot follows it). By stabilizing the frame’s corners, it will deflect less, increasing power and spin production simultaneously. Additionally, the special-treated spiral carbon offers improved dampening properties while the high modulus graphite provides strength and needed rigidity.
