Product Description Designed for better players, the KBS Tour shaft was engineered with moment of inertia analysis to increase stability from grip to clubhead to enhance the results of well-executed swings. By reducing the mass & radius of each step in equal proportions along the shafts center line, the KBS Tour shaft delivers optimum stability resulting in efficient energy transfer from the players hands to the clubhead. In addition, the KBS Tour shaft incorporated step-by-step Moment of Inertia analysis to reduce shaft interference during a players well-executed swing. The KBS Tours are also available in our signature Black Nickel finish offering a striking alternative to the industry-standard chrome. In addition to the beautiful finish, the Black Nickel reduces surface glare maximizing player focus for all iron-play.
