A shaft of the present invention is formed as an axially elongated member for use in sports equipment, such as golf clubs, fishing rods or the like. The shaft is made from composite polymers, such as a graphite composite and includes an outer sidewall which extends radially about an axis to define a substantially hollow or resin filled core. At least part of the core is divided into two or more longitudinally extending cavities by a reinforcing web or member which spans radially separate points along the shaft sidewall. The reinforcing member is preferably axially elongated anti extends at least part way along the portion of the shaft. The position of the reinforcing member is oriented in the shaft to increase the shaft rigidity against bending in the direction of bending, load and/or impact forces.
