"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.TEMPOYour swing tempo isn't just your swing speed but also your swing pace. Consider how you pull the club back, how long it hangs in the air and how quickly you swing through the ball. Swing tempo helps indicate how the club is loaded and how the club will react through impact.TRAJECTORYGolfers who want a low, penetrating ball flight should choose a shaft with a lower trajectory.SPINSelecting the correct shaft spin helps maximize carry distance and optimize landing angle.スペックTAPERED IRONS FLEXWEIGHTDIA.
