Lightweight, low-torque, composite golf club shafts with bent tips and methods of manufacturing such golf club shafts are disclosed herein. Some methods involve the use of pre-bent, rigid tubes that remain inside the finished composite shafts to support their bent tip structures. Other methods require the use of cores (which may be flexible and/or dissolvable), which support the composite shaft precursors when they are placed into forming molds to form the bent tips. These cores may be removed at the end of the bending process. Still other methods incorporate the use of bladders to provide support for shaft tips when they are subjected to molding forces.
