The construction and functionality of the shaft have a significant impact on the golf swing. The average weight difference between shafts made of steel and graphite is around 50g. Assuming that steel shafts weigh around 110g on average, graphite shafts weigh around 50g , which is lighter than steel shafts. The difference between steel shafts and graphite shafts is the material. Steel shafts are heavy because they; are made of steel, graphite shafts are light due to the fact that they; are made of carbon fibers; and the specific gravities of steel and carbon are totally different.
