Abstract:
A golf club set 2 includes a plurality of golf clubs 41 to 45 having different club lengths. Each of the golf clubs 41 to 45 includes a head 6, a shaft 8, and a grip 10. The club length of each of the clubs 41 to 45 is 38.5 inches or greater and 42 inches or less. Face progression of the head 6 is substantially constant. If a moment of inertia of the head about an axis line of the shaft is defined as MI, an MI difference ratio between the adjacent clubs is equal to or less than 3%. Preferably, a loft angle is equal to or greater than 17 degrees in each of all the clubs 41 to 45.
