Abstract
A sports racket includes a handle and a racket head frame. String holes are formed through the head frame into a string opening defined within the head frame. Rocker assemblies are mounted upon the head frame and a racket string trained over them. Each rocker assembly includes a rocker mount and a rocker member. The rocker mount has an outwardly facing rocker support surface. The rocker member has a rocking surface which rests against the rocker support surface. The rocker member is durably attached to the rocker mount. The rocker member transfers string tension between adjacent chords of a racket string.
