New technology in Fujikura is composited carbon and steel. It is for Hybrid shafts.It helps to aim the green with MCH.FeaturesMetal Composite Technology(MCT)This is the trade name showing technology and concept developed to unite metal and CFRP.Comparing MCT with conventional graphite;50〜70g are helps to rise the ball and high trajectry.80,90g is for golfers using MCI100 or 120. It helps to control easily.Over 90% of progolfers are using the carbon shafts.(By darell)Tip-dia is 350tip.The best gravity pointMCT is helpd to the best gravity point.スペックModelFlexLengthWeightTorqueTip-DiaButt-DiaK.P.MCH 50R42.053.54.58.9515.05M/HS55.015.10MCH 60R63.53.715.10M/HS65.015.15MCH 70R76.03.315.10M/HS77.515.15X80.515.20MCH 80S85.03.115.25L/MX86.515.30MCH 90S93.52.715.35L/MX95.015.40
