Cobra King F9 Speedback Irons

At COBRA, we aren’t afraid of innovation. Sometimes, a technology or innovation is so bold, it doesn’t need to be understated. Revolutionary SPEEDBACK Technology achieves the ultimate combination of low CG and high MOI, delivering the most powerful, stable and accurate COBRA iron.

Features & Benefits:

• Low CG SPEEDBACK Sole – Mass is added low and back using a belt of steel that wraps around the back perimeter of the iron, creating a lower and deeper CG that maximizes ball speed, launch and carry. SPEEDBACK shaping strategically elevates the weight from the sole contact area to maintain a conventional sole width.
• High MOI Design – To maximize performance, SPEEDBACK shaping adds more mass low and wide compared to a traditional iron. A combined 33 grams of tungsten is added to the heel and toe in the 4-7 iron, increasing MOI by 10% in the long irons for maximum stability, high inertia, and substantial improvements in ball speed, distance and forgiveness.
• Increased Stability & Inertia – To maximize performance, SPEEDBACK shaping adds more mass low and wide compared to a traditional iron. A combined 33 grams of tungsten is added to the heel and toe in the 4-7 iron, increasing MOI by 10% in the long irons for maximum stability, high inertia, and substantial improvements in ball speed, distance and forgiveness.
• Forged E9 PWRSHELL Face – An E9 variable thickness face design is 1.8 mm at its thinnest point, expanding the SWEET ZONE area on the face. A forged PWRSHELL design features a deep undercut sole with a 1.2 mm internal Speed Channel that absorbs and returns more energy to the ball for higher launch and faster ball speeds.
