Gamma updates the king of super oversize racquets. With its extended 29 inch length, you cannot get more reach legally. The 137 square inch headsize gives the RZR Bubba a massive sweetspot with very little off-center shock. Ideal for players with shorter strokes, Gamma uses the RZR Advanced Aerodynamics technology to make this one easy to swing. With the extended length, large stringbed and high swingweight (412 RDC), this racquet has all the ingredients for raw power. Surprisingly, for all its pop, our TW playtesters discovered exceptional control from the baseline, even when they swung big. And swinging big was no problem for our testers because this one definitely plays lighter than its beefy swingweight. With its extra length, the RZR Bubba provides major leverage on serves with easy access to spin and pace. Volleys feel extremely stable and powerful, with enough reach for defensive stabs and enough power for easy put-aways. Beginners in search of a very user-friendly racquet or older players who may have lost a step should definitely give this one a serious look.

Note: Due to the super oversize head, please order 2 sets of string.

GAMMA RZR racquets were designed reduce drag allowing more acceleration and speed in the natural swing. The rounded radius surfaces, Tapered Bridge Beam and Low Profile Bumper allow the RZR to easily displace and channel air around the frame regardless of the angle of attack, improving racquet head speed on every shot.
