Proforce AXIVCore Blue 59, 69, 79 integrates a true weave — 4-axis material — within the inner walls of the butt section that provides stability and consistent shaft recovery. This counter-balanced shaft series also reduces club heft, helping players gain more MPH of clubhead speed. The Blue Series’ active tip section provides a higher launch for longer carry distance, and is available in multiple weights and flexes to fit various swing profiles.
