RacquetWorld.com has the largest selection of Gearbox Racquetball Racquets in the World. From the Gearbox M40 Series to the Gearbox GB-50 Introduction Racquet. Our Exclusive Gearbox Feather 250 Racquet was so popular we worked with Gearbox to bring back the Original 250 series. We also have the Gearbox GBX1 10th Anniversary Series exclusively in all weights. Gearbox makes their racquets in 2 frame types, teardrop and quadraform. Teardrop racquets in the 165 and 170 weight range are for the Power Player while Quadraform racquets in the 165, 170, and 185 weights offer more control.
