. Greetings, This thread is for our new comers to Badminton Central. What does it mean?... The "U", the "G" and the "tension" specifications of a Badminton racket. Each brand of manufacturers make different series of rackets. Within each series manufactured, there are different models. And within each model manufactured, there are different specifications: weight, grip size and racket tension. Badminton racket specifications: The weight is denoted by "U"; the smaller the number, the heavier the weight. The grip size is denoted by "G"; the smaller the number, the larger the handle size. The racket tension is denoted by "x lb to y lb"; the minimum to the maximum stringing tension recommended. Perhaps in the future, we will get another specification to denote the stiffness of the racket shaft. Cheers... chris@ccc .
