Abstract: An adjustable golf shaft for a golf club which allows a child to use the same set of golf clubs during childhood and into his or her teen years. The golf shaft has a first shaft member, a second shaft member telescopically positioned within the first shaft member, and a compression fitting which fixedly attaches the first shaft member to the second shaft member at a desired golf shaft length. As the child grows, the compression fitting can be loosened, the second shaft member can be expanded outward from the first shaft member lengthening the golf shaft, and the compression fitting can be tightened fixing the first shaft member relative to the second shaft member.
