    • A plurality of two or more golf club shafts designed to optimize the performance of a specific shaft with respect to a specific golf swing is disclosed herein. More specifically, the present invention discloses a plurality of two or more golf club shafts wherein a dramatic difference in torque can be achieved by two golf club shafts within the same weight classification regardless of the flex of the shaft. A plurality of golf club shafts in accordance with the present invention may generally a difference in weight-to-torque ratio of greater than about 1.5 and a difference in butt-frequency-to-torque ratio of greater than about 8.0 between any two golf club shafts within the plurality of golf club shafts.
    • 这里公开了多个设计成相对于特定的高尔夫挥杆来优化特定轴的性能的高尔夫球棒杆。 更具体地,本发明公开了多个两个或更多个高尔夫球杆杆,其中不管轴的挠曲如何,两个高尔夫球杆轴可以在相同的重量分级内实现扭矩的显着差异。 根据本发明的多个高尔夫球杆轴可以在任何两个高尔夫球杆之间通常具有大于约1.5的重力 - 扭矩比和大于大约8.0的对接 - 频率 - 扭矩比的差异 多个高尔夫球杆轴内的轴。
