Abstract
A tennis racquet has a frame which includes a frame head portion with an outwardly facing stringing groove and an inwardly facing surface which is generally convex. The stringing groove includes a pair of angled side wall surfaces. A series of stringing holes extend through each side wall surface and the opposing convex surface to define holes for a pair of generally parallel stringing surfaces. Preferably, the string holes extend at an angle of about 45.degree. relative to the central plane of the stringing area, and the angled surfaces in the stringing groove, and the opposing surface on the convex surface, are parallel to one another and generally perpendicular to the direction of the string hole.
