Golf club head with improved aerodynamic characteristics
A golf club head comprising an aerodynamic hosel is disclosed herein. In one embodiment, the hosel has an upper portion and a swept transition portion which connects to the golf club head, and all points at which the swept transition portion contacts the club head are spaced rearwardly from a vertical face plane. In a further embodiment, both the upper portion and the swept transition portion comprise coaxial shaft receiving bores. In yet another embodiment, the swept transition portion of the hosel has a trailing edge that is truncated, or that has one or more surface discontinuities. In yet another embodiment, the swept transition portion has a height and a diameter, each of which is less than or equal to one inch.
