Introduced in 2006, this ultra light and manueverable Ruben Gonzalez frame has been a hit with men and women of all ages. If the racquet feels too lite in your hand, pop in some Ektelon Power Plugs at the top of the frame to increase the swing weight. You can"t go wrong with an O3 RG in your hand! Power Level: 2900 Weight (unstrung): 165g Grip Sizes: SS Grip: MaxTack
