Wilson adds another chapter to the legendary Pro Staff RF 97 Autograph - a racquet specially engineered for Roger Federer, the man who helped design it. Although it has the same target specs and outstanding playability as the original RF 97, Wilson and Federer have created an update for the ages. From its sleek black matte finish to the small silhouette of Federer and laser engraved graphics, the RF 97 is Wilson's most scrupulously detailed frame. Even the racquet’s texture has been redesigned to match Federer’s preference - a nuance that makes for easier adjustments as the racquet is spun and repositioned in response to incoming heat. Like its predecessor, this update deploys Wilson’s timeless Pro Staff formula, including a braided graphite layup, headlight balance, thin beam and Perimeter Weighting System. Toss in a thin leather grip and the result is a truly classic feel. Unlike the iconic 6.0 85, this re-engineered Pro Staff has a slightly wider, more angular beam, giving it a decidedly more powerful delivery than most traditional player's racquets. At 12.6 ounces strung, Federer’s Pro Staff gives you massive plow-through and tour level stability, allowing you to redirect heavy pace with impressive ease.
