Golf club

A golf club includes a head; a shaft having a tip end and a butt end; a grip; and a weight member that is located in a butt end region having a distance from a butt end of the grip of less than or equal to 100 mm. The grip and the weight member constitute a grip-weight portion. The shaft, the grip, and the weight member constitute a shaft-grip-weight portion. The shaft has a weight of less than or equal to 40 g. The shaft has a shaft torque of less than or equal to 7.0°. The grip-weight portion has a weight of greater than or equal to 40 g. A ratio W1/W3 of a weight W1 of the butt end region to a weight W3 of the shaft-grip-weight portion is greater than or equal to 0.40.

Golf club

A golf club includes a head; a shaft; and a grip. The head has a weight Wh of greater than or equal to 195 g. The golf club has a club length Lc of greater than or equal to 45.0 inches. The golf club has a club weight Wc of greater than or equal to 295 g. The golf club has a swing moment of inertia Isw of less than or equal to 5470×10.sup.3 (g.Math.cm.sup.2). The swing moment of inertia Isw (g.Math.cm.sup.2) is calculated by the following formula (1):
Isw=Wc×(Lg+40).sup.2+Ic  (1),
where Wc represents the club weight (g), Lg represents a distance (cm) in an axial direction between a butt end of the grip and a center of gravity of the golf club, and Ic represents a moment of inertia (g.Math.cm.sup.2) of the golf club about the center of gravity of the golf club.

Sports equipment for functional training

Sports equipment comprising a handle and at least one stem made of soft and light material fixed and aligned to the handle. The weight of the handle is considerably greater than that of the stem.

ADJUSTABLE PUTTER SHAFT STIFFENER

A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

WEIGHTED GOLF GRIP
20210121752 · 2021-04-29 ·

A grip assembly comprising a grip body that extends between an upper butt end and a distal end. The grip body has a topside and a pair of sides that extend from the topside to a rear underside. The grip body defines a bore extending between the upper butt end and the distal end. The rear underside of the grip body defines a surface and a channel in the surface. An outer wrap permanently encases around an entire circumference of the grip body along a portion of a length of the grip body.
