Invade your opponent's game with the E-Force Invasion 175!  E-Force has improved on their previous line by adding even more High Octane Boosters that, when paired with the Quadraform head shape, gives you explosive power from the stringed and more comfort on off-center shots.  Of course E-Force has kept their other patented technologies in the frame to ensure that they're putting out one of the hardest hitting frames on the market.  Once you get this frame in your hand, you'll know the meaning of power and send your opponents into retreat.
