发明名称 Method for fitting golf club
摘要 A fitting method includes steps of preparing a relationship C of a shaft flex point Y and a face angle X before impact or at impact; measuring a subject's face angle X before impact or at impact by using a test club; and selecting a shaft fitted to the subject on the basis of the measured face angle X and the relationship C. The relationship C is created by using correlation R of the face angle before impact or at impact and a hitting result. The correlation R is based on hitting results of a plurality of golf clubs having different shaft flex point rates. Preferably, the relationship C is a relational expression F1.
