About the Cobra KING Speedzone
The KING Speedzone is Cobra's 2020 game-improvement iron and the standard-length version of a set that was also sold in ONE Length. It was Cobra's first iron with a carbon fibre topline, which saves about three grams to lower the centre of gravity, combined with a forged PWRSHELL face insert whose thin area is roughly a third larger than the previous generation and which wraps into an eight per cent deeper undercut. Speedback shaping carries over the low-and-back mass distribution from the driver line. Lofts are very strong: the 7-iron is 27.5 degrees and the pitching wedge 42.5 degrees, on a 37.25-inch 7-iron. The stock set is seven clubs, 5-iron through gap wedge in both 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 Speedzone 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.
