Introducing the RF 01 Future. Stamped with insights gleaned from Federer's legendary career, the RF 01 Future puts the geometry and technologies of Federer's RF 01 Pro into a very maneuverable package, making it easy for dedicated beginners and early intermediate players to swing with confidence. In addition to its quick handling and arm-friendly stiffness rating, the Future packs a 98-square-inch head, providing the kind of accuracy that breeds confidence when the set score tightens. This racquet's design is appropriately named SABR, a moniker that epitomizes Federer's attacking style. Under the hood, it includes a powerful carbon fiber layup with Braid FORTYFIVE technology to enhance both dwell time and pocketing while helping the racquet bend in ways that complement the vertical mechanics of the modern game. It also features foam throughout the racquet to deliver a more solid feel, along with a reinforced shaft and yoke for more torsional stability through impact (think less racquet flopping on volleys). Ultimately, the RF 01 Future gives improving intermediate players the tools to play confident tennis.
