    Abstract: The invention relates to a sports racquet having a head having a string bed is attached to two throat beams that extend continuously downward to a shaft having a handle. Each throat beam contains a bending zone in which the width of the throat beam parallel to the string bed and the width of the same throat beam perpendicular to the string bed gradually changes in equal, but opposite, dimensions such that the circumference of the throat beam remains substantially constant through at least the length of the bending zone or the length of the entire throat beam. Where the width of the throat beam parallel to the string bed is the widest and the width of the throat beam perpendicular to the string beg is the narrowest defines the flexible cross-section or flex point of the bending zone.
