Provided is a golf shaft, capable of ensuring bending rigidity required for a golf club and providing good hit feeling in a composite shaft with 50 g-130 g. The golf shaft comprises an element tube made of metal, an outer layer made of a fiber reinforced plastic and covering an outer periphery of the element tube over an entire length of the element tube in an axial direction, an adhesive layer interposed between the element tube and the outer layer to bond between the element tube and the outer layer, wherein weight of a whole including the element tube, the outer layer, and the adhesive layer is 50 g-130 g, and weight of the element tube is 50%-90% of the weight of the whole.

A piece of tubular sports equipment includes: a first layer of composite material including fibers oriented in a first direction; a second layer of composite material that directly contacts the first layer of composite material, that is arranged radially outwardly of the first layer of composite material, and that includes fibers oriented in a second direction that is different than the first direction; and a third layer of composite material that directly contacts the second layer of composite material, that is arranged radially outwardly of the second layer of composite material, that includes fibers oriented in a third direction that is different than the second direction, and that includes an aperture formed through the third layer such that a portion of the second layer is visible through the aperture.

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.

A sport apparatus comprising a shaft, wherein the shaft comprises a notch fitting and a sensor housing. The sensor housing comprises an alignment rib fitting, printed circuit board, rechargeable battery, one or more motion sensors, a transceiver, an inductive charging coil, among other necessary elements for the sport apparatus as described herein. A portion of the sensor housing resides within the shaft, wherein the alignment rib of the sensor housing mates with a notch or other locking mechanism of the shaft.

A configurable golfing apparatus including a rectangular handle portion. The rectangular handle portion includes a golf club shaft that is securely mounted within the configurable golf club handle. The rectangular shape provides new and additional hand placement and new and additional configuration capabilities for both right handed and left handed golfers. The configurable golfing apparatus allows different golf club heads (e.g., drivers, irons, putters, etc.) to be inserted and removed from the configurable golfing apparatus. The golf club shaft inside the rectangular handle portions complies with straightness, bending and flexibility, and twisting and torque, properties and attachment to a golf club head requirements for a golf club shaft required by the United States Golf Association (USGA) and Royal and Ancient (R&A) Golf Club of St Andrews rules and functions in a manner similar to a golf club shaft not enclosed in a rectangular handle portion.

An example golf club shaft includes an extended body and a core. The core is disposed in the extended body.

A unique and innovative shaft for a golf club significantly enhances stability and shock absorption during golf swings. Taking advantage of the excellent flexibility, surface strength and shock absorption of a bamboo pole, the shaft is designed following the physical structure of the bamboo pole, thus helping facilitate vibration damping and absorption, stability during golf swings, supersymmetry and balance. The shaft comprises a plurality of connectors, each of which is a solid material and connects a plurality of links into an elongated member of the present invention. The plurality of connectors may be attached to the inside wall of the elongated member when designed as a tube. By varying the positions of connectors across the elongated member, the bamboo-inspired shaft can be configured to feature desired levels of flexibility and corrective/reversible torsion at one or more points on the shaft, thus help any golf player achieve substantial performance improvements.

A golf club head has a body defining a ball striking face. The body further has a first leg extending away from the ball striking face and a second leg extending away from the ball striking face wherein a void is defined between the first leg and the second leg. The body further defines a cover that extends over the void. The golf club head may further have support structures and adjustable weight members.
