Mitsubishi Tensei CK Driver Shaft Review
The past focus of Golf Shaft Reviews had been aftermarket shafts. With this review I am creating a new category, OEM shafts. The typical market price of an aftermarket driver shaft ranges from $300 to $1000. Those shafts are not supplied in off the rack drivers. In the not to distant past we would see the notation “Made For” or “Engineered For” on these shafts. That notation came to be recognized by the golfer for what it was. Several years ago it disappeared and the labeling of the OEM ‘Made For” shaft became much more subtle. A reasonable person understands that he is not going to get a $400 ultra premium shaft in a $400 driver. Unfortunately, many of the clerks in the retail side of the golf business are unaware of the subtle changes in graphics now used to label aftermarket and OEM shafts.
This is not a condemnation of the shafts made for the club companies that are installed in off the rack drivers. A great many golfers play a lot of good golf with these shafts. And generally the quality of all shaft has improved over that last several years. The difference is in the materials used. Those differences are most easily seen in the measurements torque and hoop deformation. In my experience those two properties affect dispersion. It is not difficult to produce bargain shafts with the same linear stiffness properties of some of the premium shafts. It is impossible to reproduce the matrix of stiffness, weight, torque and hoop strength that comes with exotic materials and high density prepreg that is used in premium shafts.
The Tensei CK Pro Blue, Tensei CK Pro White and Tensei CK Pro Orange have been reviewed earlier. They feature a long section of Carbon Fiber Dupont Kevlar “CK” material woven into the butt section of the shaft. The Pro Blue and White feature Boron reinforced tips. The notation Boron Tip is printed on the tip of the shaft. The Boron material is not included in the tip of the non “Pro” version of the shafts. The Tensei Pro Orange has a material called MR70 which Mitsubishi states is stiffer than Boron. The EI profile of the Tensei CK Pro Orange validates that claim. Let’s take a look at other subtle graphics and what the profiles of the Tensei driver shafts you will find in off the rack clubs.
