Abstract
Provided is a golf club having a head disposed at a front end of a shaft and a grip disposed at a back end of the shaft. A club weight is not larger than 290 g, and a ratio (head weight/club weight) of a head weight to a club weight is not lower than 0.67 but not higher than 0.72. Furthermore, a grip weight is not smaller than 27 g but not larger than 45 g, and when a distance from the front end of the shaft to a center of gravity the shaft is LG and when a full length of the shaft is LS, 0.54≦LG/LS≦0.65 is satisfied.
Claims18
A golf club having a head disposed at a front end of a shaft and a grip disposed at a back end of the shaft, wherein
- a club weight is not larger than 290 g,
- a ratio (head weight/club weight) of a head weight to the club weight is not lower than 0.67 but not higher than 0.72,
- a grip weight is not smaller than 27 g but not larger than 45 g, and
- when a distance from the front end of the shaft to a center of gravity of the shaft is LG and when a full length of the shaft is LS, 0.54≦LG/LS≦0.65 is satisfied,
- wherein when a weight of a butt partial layer existing in a range from a butt end of the shaft to a point separated from the butt end by 250 mm is represented as Wa, and when a weight of the shaft in the range is represented as Wb, Wa/Wb is not lower than 0.4 but not higher than 0.7.
