Novak Djokovic’s new secret weapon from HEAD. Speed powered by G.
HEAD tennis has released this promo of its 2013 Speed tennis racquet powered by G.
What "G" is or involves we won't know until January 11 (my guess is G-spot). Apparently Novak Djokovic is a user. You can be too by entering the company's newest contest over at facebook.com/headtennis.
