For Roger Federer's last year on tour, he needed a tennis racket that would help him compete with the new generation of heavy baseliners while maintaining his all-court style. The Wilson RF 01 is inspired by that racket. It's lighter than our RF 01 Pro, making it a more maneuverable version. It features the same SABR Frame Design that gives it versatility, allowing for the pace, spin and direction changes signature to Roger's game. You'll notice a fast head speed thanks to Glide Guard B&G and a great ball-pocketing feel from Braid 45 Technology. Wilson RF 01 Tennis Racquet | 4 1/4 | Christy Sports
