1. A golf club head comprising:
- a striking face portion, defining a striking face plane, positioned at a forward portion of said golf club head;
a body portion, connected to an aft portion of said striking face, positioned at a rearward portion of said golf club head; and
a hosel, defining a hosel bore axis, positioned at a heel portion of said golf club head, and adapted to connect to a shaft,wherein a first plane intersects a second plane to define a hosel sub-element,said first plane parallel to both said hosel bore axis and said striking face plane and is offset 15 mm towards said rear portion of said golf club head from said hosel bore axis in a ZHBA direction, andsaid second plane parallel to said hosel bore axis and perpendicular to said striking face plane and is offset 12 mm towards a toe portion of said golf club head from said hosel bore axis in a XHBA direction;
wherein said hosel releasably connects said shaft to said golf club head; and
wherein said hosel sub-element has a total mass of less than about 50 grams.

Abstract
A golf club head with an improved Moment of Inertia (MOI) is disclosed herein. More specifically, the present invention relates to a golf club head with a releasable hosel mechanism that is leaner and more lightweight, it allows a significant amount of weight to be saved from the hosel portion of the golf club head and used to improve Center of Gravity (CG) location of the golf club head; which contributes to the improvement of the MOI of the golf club head.
