Abstract
In a sports racquet, anchor points for a string are marked with indicia to assist a stringer in stringing from one anchor point to a next anchor point. In a preferred embodiment, one of the anchor points is a bearing assembly located within a hollow cavity in the racquet stem. Colored tubes are placed in the stem that lead to and from the bearing assembly, and the colors of the tubes match respective colored indicia associated with string holes in the frame head.
