ABSTRACT:
A golf club shaft is disclosed. The golf club shaft includes an elongated tubular member having an outer surface and a longitudinal axis. The elongated tubular member has a plurality of channels formed about the outer surface of the elongated tubular member and extending substantially parallel to the longitudinal axis. The plurality of channels are shaped and dimensioned to create air flow about the elongated tubular member, reducing air resistance as the golf club shaft is swung by an individual.
