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 and radius of each step in equal proportions along the shaft’s center line, the KBS Tour shaft delivers optimum stability resulting in efficient energy transfer from the player’s hands to the clubhead. In addition, the KBS Tour shaft incorporated step-by-step Moment of Inertia analysis to reduce shaft ‘interference’ during a player’s well-executed swing.
Golfers have been waiting for years to see a tangible difference in steel shaft design, so FST proudly introduces the KBS Series steel shafts — an all-new remium line of steel shafts engineered by industry-acclaimed steel shaft designer Kim Braly and featuring advanced Moment of Inertia technology.
A one-of-a-kind design created from unique engineering analysis, the KBS steel shafts deliver optimum stability resulting in efficient energy transfer from theplayer’s hands to the clubhead. KBS steel shafts feature a proportionately equal reduction in shaft mass and step radius along the shaft’s entire center line. In addition, KBS shafts reduce shaft ‘interference’ during the swing which means greater performance for you with every shot. “Shaft performance is critical in placing the clubhead in the correct position at impact, but most steel shafts on the market today fail to reach the level of performance and feel necessary to respond effectively in the players’ hands, especially just prior to impact,” says Braly, whose steel shafts designs are currently being played by Top 10 players in the world. “The KBS steel shafts use an intelligent design to upgrade the performance with MOI technology and a proportional reduction in mass and radius during the step progression.” FST researched a wide variety of tubular structures that endure large stresses or loads and applied a revolutionary new approach with MOI analysis. KBS steel shafts also incorporate FST’s highquality precision manufacturing processes:Exclusive ‘Oil-Quench’ tempering method which produces shafts that are arrow-straight from butt to tip.Higher-than-traditional center of gravity construction to allow for more mass in the clubhead.Matching shaft weight and frequency to the strictest tolerances to ensure peak playing performance and guaranteed repeatability.
