In a number of events in 2019, Fowler used a King SpeedBack long iron to take advantage of the greater forgiveness and distance. The new SpeedZone irons are replacements for those designs, so it will be interesting to see whether or not he upgrades in 2020.
Either way, like the old SpeedBack irons, the new SpeedZone irons are made with ultra-low CG for increased ball speed. Looking down on the product at address, golfers will easily detect Cobra’s new carbon fiber topline, which replaces steel in the 4-7 irons to save weight. According to Cobra, the carbon fiber saved 3 grams that was placed lower in the heads, ultimately increasing ball speed and launch.
Additionally, Cobra uses perimeter weighting, wide bodies and an undercut speed channel to increase speed and forgiveness in the SpeedZone irons. To optimize spin and trajectory throughout the set, the long irons (4-6) have V-grooves to reduce spin, the mid irons (7-PW) have U-grooves to “optimize spin,” according to Cobra, and the wedges (GW and SW) have wedge grooves to increase spin on shots around the green.
The SpeedZone variable length and SpeedZone One-Length irons will sell for $799 per set. The one-length irons have matching 37.5-inch lengths, but they have progressive shaft weighting for higher launch in the long irons and lower launch in the short irons, and “fine-tuned lie angles,” according to the company.
