キャロウェイゴルフ Great Big Bertha 23 Irons

This is the titanium iron reinvented--Callaway’s first ultra-premium multi-piece, titanium design. We are combining driver-like power with the precision of an iron. By combining our titanium face and body with up to 145g of tungsten, we’ve reached a new level of speed, forgiveness, and overall performance.Forged Titanium Face & CP4 Titanium Body By leveraging materials that are typically reserved for drivers, we’ve generated up to 96g of discretionary weight, and precisely repositioned this saved weight to increase launch and forgiveness. The Commercially Pure Grade 4 (CP4) Titanium body flexes more at impact than traditional steel and works together with the thinner face to transfer more energy to the ball. Tungsten Speed Cartridge The Tungsten Speed Cartridge features up to 145g of high-density tungsten, which provides increased speed and launch by giving us the deepest center of gravity we’ve ever achieved in an iron. This unmatched level of tungsten is a 133% increase over Rogue ST Max, and the most ever in a Callaway iron. A.I.-Designed Forged Titanium Face The forged titanium face is optimized to increase speed and improve spin consistency. Great Big Bertha is the first Callaway iron to combine titanium and industry-leading A.I. technologies for optimized performance. Patented Urethane MicrospheresOur patented urethane microspheres enhance sound and deliver a softer feel, while still allowing the face to flex for more ball speed.スペックMODEL456789PWAWSWLOFT20°23°26°30°34°38°43°48°54°LIE60.5°61.25°62.0°62.5°63.0°63.5°64.0°64.0°64.0°LENGTH38.75”38.125”37.5”37”36.5”36”35.75”35.5”35.25”OFFSET5.08mm4.57mm4.06mm3.81mm3.56mm3.30mm3.05mm2.79mm2.54mmSWING WEIGHTD1 (Graphite, Steel)HANDRH/LHRH/LHRH/LHRH/LHRH/LHRH/LHRH/LHRH/LHRH/LH
