Black Gold introduces Frequency Tuned™ technology. Incorporating True Temper's proprietary "Gold" manufacturing process, each critical shaft parameter is held to unparalleled standards resulting in the first shaft ever to combine pinpoint frequency specification with exacting weight tolerances and balance for unmatched repeatability and consistency. •Frequency Control - each Black Gold shaft is frequency tuned to within +/- 1 CPM. •Weight Control - each Black Gold shaft is manufactured to within +/- 1.5 grams. •Balance Point Control - each Black Gold shaft features balance point control to +/- .125". Grip To TipTM Technology Utilizing True Temper's manufacturing expertise, the shaft's taper rate is held at a remarkably constant reduction producing Black Gold's proprietary Grip To Tip™ flex profile. This unique design characteristic allows the shaft to efficiently store the force created in the downswing for maximum energy transfer at impact. Premium Gold Nickel Coating An exclusive feature making Black Gold truly unique is the proprietary "gold nickel" plating process that gives the shaft its distinct appearance. This proprietary plating process produces a distinctive gold shading effect over time for the ultimate expression of individuality and personality.
