About the Cobra KING Radspeed
The KING Radspeed is Cobra's 2021 game-improvement iron and the standard-length version of a set that was also sold in ONE Length. It carries a forged PWRSHELL face insert in thin 17-4 stainless steel, designed to flex at both the face and the sole, behind a carbon fibre topline that saves about two grams and is finished in black to make the topline look thinner at address. RADIAL weighting and a 3D-printed lattice medallion tune mass distribution and damping. Lofts match the previous Speedzone set exactly at 27.5 degrees in the 7-iron and 42.5 degrees in the pitching wedge, on a 37.25-inch 7-iron. The stock set is seven clubs, 5-iron through gap wedge in right and left hand, with a 4-PW option in right hand. Lengths below are the standard-grip figures rather than the COBRA CONNECT ones, swing weights are the steel-shaft values, and offsets are converted from Cobra's published millimetre figures.

Finding a used set
The Cobra KING Radspeed is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
