      Wilson Blade SW104 v7 Autograph Countervail

      The new Wilson Blade SW104 V7 Autograph Countervail tennis racquet brings cutting-edge FeelFlex technology to players who prefer a larger sweet spot. FeelFlex strategically places carbon mapping throughout the frame to allow players to feel more connected to the ball during gameplay. The Blade SW104 V7 Autograph Countervail is made of Braided Graphite + Basalt for a classic feel, and the Parallel Drilling provides a consistent, more forgiving string bed response. This iteration of the Blade also includes a Top Grip Taper for increased grip comfort, especially for two-handed backhands.

      • Serena Williams' racquet of choice.
      • Larger head size provides an enhanced sweet spot.
      • Clean tri-colored design with lime green, black, and silver elastic paint.
      • Reduced spec variance (+/- 5.5g) for added consistency from frame to frame.
      • 20% more flexible for more feel and comfort.
      • 11.4% more stable for more power.
      • 12% more vertical bending for more topspin.
