ABSTRACT:
A racquet string is provided that integrates a non-circular string substrate with a solid lubricant. The combination of lubrication with an elongated shape allows woven racquet strings to be easily displaced while striking a ball, yet able to rebound quickly to their originally strung positions. These features improve spin control, reduce racquet vibration, improve ball rebound consistency, and lengthen string life.
