ABSTRACT:
A sports racquet comprises a handle and a frame coupled to the handle. The frame includes an inner portion and an outer portion located substantially opposite the inner portion. The inner portion of the frame include a plurality of undulations that extend towards and away from a ball-hitting surface, the undulations reducing the unintended bunching and wrinkling of material that intermittently forms in the frame during the manufacturing process. The undulations can be varied by location, undulation length, undulation height, and frequency and can be used in racquets made from a variety of materials and methods.
