PROBLEM TO BE SOLVED: To provide a set of golf club shafts, while satisfying functions such as carry, direction or the like required for each golf-club number of the set, for obtaining a similar good hitting feeling in the every number.SOLUTION: The set of golf club shafts is used for a set of golf clubs, wherein each club has: a front portion F to which a golf club head is attached; a rear portion R to which a grip 18 is attached; and a mid portion M between the front portion and rear portion, while the length shortens with the increase in the golf-club number. In the mid portion M of each shaft 12, a minimum flexural rigidity part S3 where the flexural rigidity is the lowest is arranged, while the flexural rigidity is increased from this minimum flexural rigidity part S3 to the front and rear ends. The length and the flexural rigidity at the front portion F of the respective shafts 12 are all equal in the single shaft set. Further, the flexural rigidity in the mid portion M increases with the increase in the golf-club number. |
