A golf club includes a reinforcing member installed on an inner circumferential surface of a shaft near a tip-side end portion and extends in an axial direction of the shaft to straddle an upper end of a cylindrical portion. The reinforcing member has a cylindrical shape configured by laminating prepregs obtained by impregnating carbon fibers being reinforcing fibers with a matrix resin. The reinforcing member is provided with: a first bias layer located at the innermost side in a radial direction; a second bias layer laminated on an outer side of the first bias layer (16A) in the radial direction, an orientation direction of the reinforcing fibers having an opposite direction to the first bias layer; and a straight layer laminated on the outer side of the second bias layer in the radial direction, an orientation direction of the reinforcing fibers being parallel to the axial direction of the shaft.

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 stepless golf shaft includes; a butt portion having: a proximal end configured to be attached to a golf grip; and a distal end; a tip portion having; a distal end configured to be attached to a golf club head; and a proximal end; and a midsection connecting the proximal end of the tip portion with the distal end of the butt portion, the midsection including; a first portion having a first outer diameter that gradually decreases in the direction of the proximal end of the tip portion at a first taper rate and not having any step changes in the first outer diameter; and a second portion having a second outer diameter that gradually decreases in the direction of the proximal end of the tip portion at a second taper rate, where the second taper rate is different than the first taper rate.

Described herein is a system of golf clubs having shafts with ascending weights (shaft weights that increase as shaft lengths decrease). The system of golf clubs can be manufactured by implementing a method called “stepping”, which allows the system of golf clubs with ascending weights to be manufactured with reduced quantity of inventory.
