The Gamma RZR Bubba 117 marks the return of the beloved super oversized frame specification to Gamma’s racquet line but in a smaller head size. The ultimate sweetspot of any game improvement frame on the market today, now with a more aerodynamic beam design and a striking new graphic. The most powerful option in the RZR line, with a oversized 117 square inch head, 27.50 inch length, tapered 22/24/22mm beam, and 9.50 oz. strung weight for added forgiveness. Great option for the beginning to intermediate player with a slower swing. Quite hefty 405 swingweight, but surprisingly maneuverable and rewards those able to swing with amazing power! 16×19 string pattern to keep the power in check.

Gamma RZR racquets utilize Advanced Aerodynamics, with unique geometric contoured shapes designed to deflect and streamline airflow around the frame. Rounded radius surfaces, Tapered Bridge Beam, and Low Profile Bumper allow the RZR beam to easily channel airflow around the frame regardless of attack angle. M Carbon composite matrix increases strength at key points on the frame for optimal power transfer.

  • RZRā„¢ Advanced Aerodynamics: Unique geometric contoured shapes designed to deflect and streamline airflow around the RZR frame. These shapes provide the least amount of air resistance and drag, greatly enhancing maneuverability and racquet speed on all shots.
  • MCarbon: A composite matrix that increases strength at key points throughout the RZR frame. The result is an optimal combination of stiffness and flexibility that offers maximum power transfer on all shots.
  • Multi-Directional Layering: Carbon sheets are layered in pre-calculated directions to precisely control the fiber angle in each area of the RZR frame. This ensures optimum strength and stiffness throughout the racquet.
  • Minimized Voids: RZR frames are made using a process that removes entrapped air from the composite matrix to minimize voids between fiber layers that can fatigue the structure. Minimized voids result in maximum frame durability and a solid, comfortable feel.
