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 Future is inspired by that racket. It's our lightest RF racket of the collection with a slightly higher balance, making it highly maneuverable with additional power for next-generation players. The SABR Frame Design 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.
