STABILITY. PLAYABILITY. FEEL.
Steel is #1.
Steel shafts are the No. 1 choice for irons on all pro tours. Golf professionals and skilled amateurs alike appreciate consistency and accuracy and, as a result, have long preferred steel shafts in their irons.
Steel provides unmatched stability and a fresh feel for true feedback at impact, and the all-new KBS Steel Shafts use an intelligent design to enhance steel performance even more with Moment of Inertia (MOI) Technology combined with a proportional reduction in mass and radius during the step progression. As a result, premium KBS Steel Shafts are engineered to respond to your hands, especially just prior to impact, and optimize every shot KBS Technology
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 premium 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 the player’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.”
The new KBS Series steel shafts are unlike anything on the market today. 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 high-quality precision manufacturing processes, such as:
Exclusive ‘Oil-Quench’ tempering method which produces shafts that are arrow-straight from butt to tip.
Tapered tip construction to provide a solid metal-to-metal bond in the hosel and tour-proven feel at impact.
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.
FST remains exclusively dedicated to the design and development of high-quality steel golf shafts, and KBS technology will re-introduce true performance benefits of playing steel to golfers around the world. |
