Cobra King RADSPEED Irons - Steel Shafts
With a name inspired by its key technology, Radial Weighting, the design of these irons is aimed at maximising performance through the strategic placement of weight relative to the Center of Gravity (CG) to optimise speed and forgiveness. COBRA engineers discovered that by positioning more mass low on the heel and toe (the two furthest points from the CG while remaining low in the head), they could lower the CG while dramatically improving the stability of the clubhead. 10g, in the form of a screw-in weight, is positioned in the toe and 3g of mass, is positioned in the heel to create the best combination of low CG, and high MOI for the fast ball speed and high launch.
The 10g screw is a nominal weight used by COBRA to guarantee perfect head weights for improved builds. During custom builds this weight may be adjusted +/- 6g utilising weights ranging from 4g to 16g in increments of 2g to dial in proper swing weights when customising length or shafts. This weighting system delivers an iron set that is truly custom built for the golfer. Radial Weighting is a critical component of the design that allows the RADSPEED irons to maintain high launch and maximum carry distance, despite having a stronger loft.
In addition, the irons feature a unique Carbon Fiber Topline that saves 2g to lower the CG and improve launch and spin characteristics. An all new black carbon fiber cosmetic creates the appearance of a thinner topline for a sleeker and more compact look at address.
COBRA’s patented PWRSHELL technology continues to offer increased speed and higher launch even on stronger lofted irons. The forged PWRSHELL Face insert in the RADSPEED iron is made of a high-strength 17-4 stainless steel, allowing for a thinner and more flexible face design that increases ball speed on and around the Sweet Spot. In addition to the above-mentioned technologies, the RADSPEED Variable Length Irons feature progressive head shapes (two-piece metalwood construction on 4-7i and one-piece construction on 8-SW), groove shapes (V groove for reduced spin in the long irons and U groove for added spin in the short irons), and hosel lengths (shorter in the long irons and taller in the wedges) to optimise distance, launch characteristics, and accuracy for each respective iron category – long irons, mid-irons and wedges.
