A shaft for a golf club includes a main shaft, a ring shaft and a flex shaft which are mounted onto the distal end of the main shaft, and a sleeve which may be used to cover the ring shaft portion and the flex shaft portion. Each portion of the shaft is made of a material that is specifically selected for its particular modulus of elasticity, and the modulus of each portion is selected relative to the moduli of the other portions. For the present invention, the ring shaft portion has the highest modulus of elasticity, and the flex shaft portion has the lowest. With this combination, a club head is affixed to the extreme distal end of the main shaft, and a grip is attached to the proximal end of the main shaft portion. As intended for the present invention, the flex shaft portion of the shaft absorbs the impact and transfers the force that is generated when the club head hits a golf ball, the ring shaft portion dampens this force, and the main shaft portion transfers the impact force through the grip to the golfer in an informative and meaningful manner.
