The Wilson nCode n1 (115) is an ultra stiff game, super light, and powerful frame. It is the flagship of Wilson's nCode technology. The oversized head and head-heavy balance provide serious power for club level players. In addition to nZONE technology, the string pattern is open for more pop and spin which will please baseline players. The light weight offers easy handling for players who can't maneuver heavier frames. Overall, this frame will punch every shot, but players with long, fast strokes should stay away because this is one powerful weapon. Recommended for 2.5-3.5 level players.
