The Dynamic Gold 120 shaft delivers the tour-caliber accuracy of Dynamic Gold in a lighter weight steel shaft. Stronger players will experience the exact same profile and launch as Dynamic Gold in a shaft that is easier to swing. True Temper has spent the past 15 years focused on two specific performance categories—tour-caliber designs for the best players in the world and lightweight steel shafts. Dynamic Gold 120 represents the best performance benefits of both of these categories in one radically new design.
