Babolat has moved away from the non-environmentally friendly lead option to a friendlier option – Tungsten tape. The pack includes 3 x 3 gram Tungsten tape strips. The Babolat Balancer Tennis Tape is a Tungsten tape that adapts the weight of your racquet to fit your game. Ideally installed on inside the racket throat (“V”) or inside the racket handle. Adding this tape on the racket head can cause damage to the frame if installed on a weaker point of the frame.
