Introducing the Fujikura MCI Black Shaft - The next generation of MCI technology is now available from driver through wedge creating the ultimate weight flow throughout the entire set.
Many conventional iron shafts are constant weight so with the new design flow of the MCI Black Fujikura wants the player to experience the same feel throughout the entire set with the ideal launch angle and consistency in feel across all clubs from #1 thru #10.
Available in 2 weights MCI80 series and MCI100 series the weights still flow from light in the woods to heavy into the wedges as you can see in the spec chart below, available in R/S/X Flexes.
Fujikura also provides suggested swing weight and grip weight examples ranging from D0 in the driver to D3.5 in your wedges.
