TaylorMade r7 Iron Set 4-PW, GW with Steel Shafts An inverted cone construction gives a higher COR and ball speed on mis-hits, resulting in increased average ball speed and increased average distance, while a dampening web of soft alluminum and high-tech bonding soaks up harsh vibratoins giving the Taylormade r7 Irons a phenomenally soft-yet-solid feel at impact. With its deep cavity design, the Taylormade r7 Irons have a low and deep CG, making them easy to launch for an optimum combination of carry and control. Their moderate offset promotes the optimum combination of direction and trajectory for increased ball control and increased accuracy. T Step 90 (90-gram) steel shaft encourages a dynamic relase to promote even more speed and extreme distance, while a TaylorMade logo grip increases feel, comfort, and traction to promote the best performance of any irons you've ever hit.
