Gamma RZR Bubba 137 The Gamma RZR Bubba takes a fan favorite and makes it even better with RZR™ Advanced Aerodynamics, making it the fastest and easiest to swing Bubba ever created. With its classic 137 square inch head size and extended 29 inch length, this racquet is easier to maneuver while still maintaining the reach, forgiveness, power and sweet spot of the original Big Bubba. Players with slower and shorter swings will love the easy maneuverability and the expanded sweet spot that allows for better shots, even on off center hits, with the largest legal frame in todays game.Designed to reduce drag allowing more acceleration and speed in the natural swing.Built with MCarbon composition.Multi-Directional Layering in pre-calculated directions precisely ensures optimum strength and stiffness throughout the racquet. Technology RZR™ 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.
