The RADSPEED ONE Length irons are packed with more technology than ever before to deliver more speed, distance, and consistency. Every iron is the same length (37.5"), allowing for one repeatable setup and swing, and less variables for more consistency. 10g and 3g of mass is positioned on the toe and heel extremities to create the best combination of speed, low spin and stability for optimized performance. A 10g weight positioned low and in the toe area centers the CG and adds stability for more distance and forgiveness on off-center hits. A forged face insert is made of a thin 17-4 stainless steel, and is designed to increase flex in and around the Sweet Spot for faster ball speed and higher launch. 3D printing offers unlimited complexity in design, allowing us to produce an intricate lattice medallion structure that saves weight and fine-tunes feel.
