Widely overlooked as a part of the club, the shaft is considered by many to be the transmission of the modern clubhead. Current graphite shafts weigh considerably less than their steel counterparts, (sometimes weighing less than 50 grams for a driver shaft) allowing for lighter clubs that can be swung at greater speed. Since 1999 performance shafts have been integrated into the club making process. These shafts are designed to address specific criteria, such as to launch the ball higher or lower or to adjust for the timing of a player's swing to load and unload the shaft at the correct moments of the swing for maximum power. Whereas in the past each club could come with only one shaft, today's clubheads can be fit with dozens of different shafts, creating the potential for a much better fit for the average golfer.
