Methods of creating golf products with complex structures that would be difficult, impossible, or cost prohibitive to produce, such as lattice structures, beam structures, and complex surface-based structures, and golf products that are created using those methods, are described herein. The structures described herein may be made from metal, non-metal materials, or combinations thereof, and may have one or more portions that are made from transparent or translucent materials.

A racquet including a tubular frame formed of a fiber composite material, a pallet and a butt cap. The frame includes first and second end regions and a mid-region. The handle portion includes a distal region, proximal region and a central region positioned between the distal and proximal regions of the handle portion. The central and proximal regions of the handle portion have outer surfaces that define first and second transverse cross-sectional areas, respectively. The second transverse cross-sectional area is larger than the first transverse cross-sectional area. The pallet is coupled to and longitudinally extends over the central region but not over the proximal region of the handle portion. The butt cap is secured to the proximal region and includes a peripheral wall and less than half of the length of the peripheral wall extends over the pallet.

A golf club having unique mass properties and all the benefits afforded therefrom.

A golf club head includes a face, a crown, a sole, and defines a bore that is configured to receive and to selectively retain an elongate weight. The bore is aligned on a longitudinal axis that intersects the face. An elongate weight is insertable into the bore. The elongate weight is rotatable between a first angular position and a second angular position. The golf club head can futher include a compliant stop positioned to contact a protrusion of the elongate weight, such that a torque threshold must be overcome to rotate the elongate weight.

A golf club head including a striking face, a sole extending aft from the striking face, a crown extending aft from the striking face, a skirt extending between the sole and the crown, an interior cavity defined by the striking face, the sole, the crown, and the skirt, an aperture formed through the sole, the aperture having an aperture length and an aperture width, wherein the aperture length is substantially larger than the aperture width, and a stiffening member affixed to the sole, wherein a portion of the stiffening member resides within the aperture, wherein the sole is constructed of a first material having a first density, the stiffening member is constructed of a second material having a second density, and wherein the second density is at least 30% less than the first density.

A golf club head that is capable improving on the inertia properties of a golf club head all while also improving the Center of Gravity (CG) location is disclosed herein. More specifically, the golf club head in accordance with the present invention achieves a relative low Moment of Inertia (MOI) about the Z-axis (MOI-Z), a relatively low MOI about the Shaft-axis (MOI-SA), a low MOI about the Y-axis (MOI-Y) and a high MOI about the X-axis (MOI-X).

Some disclosed golf club heads include body having at least one raised sole portion and a cantilevered ledge extending down around a perimeter of the club head below the level of the raised sole portion. Some disclosed golf club heads include one or more sole openings in the body and a sole insert that is mounted inside the body over the sole openings. The sole can include weight tracks as well, and a rear weight track can extend between a toe side sole opening and a heel side sole opening. A crown insert can also be included that is mounted over an upper opening in the body.

A weight adjustable javelin includes an elongated shaft having a leading end and a trailing end. A nose piece includes a conical shape, a nose tip, a nose base, and an internal nose slot defined along a longitudinal axis of the nose piece. The nose base includes an opening leading into the internal nose slot. A tail piece includes a tail tip, a tail base, and an internal tail slot defined along a longitudinal axis of the tail piece. The tail base includes an opening leading into the internal tail slot. The nose base is releasably secured to the leading end of the elongated shaft. The tail base is releasably secured to the trailing end of the elongated shaft. The internal nose slot and the internal tail slot are configured to receive and retain different sized and weighted rods therein.

A process for manufacturing a putter with a bi-material shaft is disclosed herein. The putter comprises a putter head, the bi-material shaft, a mass member and a grip. The bi-material shaft comprises a body with a tip end and a butt end. The body comprises a metal section extending from the tip end to a connection point, and a composite section extending from the butt end to the connection point. The mass member is positioned within an opening at the butt end of the shaft. Mass from the shaft is transferred to the club head and the mass member in the butt end of the shaft.

An adjustable resistance apparatus includes features that protect a user from harmful heat generated during use while offering a wide range of resistances. The apparatus may be combined with a variety of accessories, such as a load cell.
