A Perfect Synergy of Technology and Materials To Improve Putting Performance

Mitigating Unwanted Flex and Twist

Why Would Any Golfer Trust Their Putter To A Cheap Steel Shaft?

The Stability design was extremely challenging; invent a shaft that had the same weight as a traditional steel putter shaft but without being too stiff, heavy or having a deadened feel. It also had to mitigate unwanted flex and twist.

Stability Shaft Technology & Equipment

Designed To Improve Putter-Specific Motion & Performance.

Stability was designed to improve putter-specific motion and performance. It increases flexural rigidity and significantly reduces torsional rotation through BGT’s patented design. It limits unwanted movement by stiffening the shaft by 25% without abolishing feel and reducing torque by almost 50%, to deliver the club face squarer at impact.

The performance of the shaft was exhaustively tested with hundreds of putters using state-of-the-art high-speed cameras, robots, SAM Putt Lab, Quintic Ball Roll software and Trackman4. Our objective was to isolate relatively small face movements that affects ball roll. Regardless of how well golfers putt, there is the human error factor that skews results. Our focus was on the putter face at impact then details ball roll till conclusion; we hit thousands of putts featuring a variety of head designs and weights to draw precise conclusions. The result was a reinvention of the putter shaft from the ground up.

“Traditional putter shafts are inherently inconsistent and can limit how well you can perform. You may have been told that your steel shaft is as good as it needs to be, but it isn’t nearly as good as it could be. The stability shaft removes inconsistencies that current putter shafts have, and it helps compensate for mistakes all golfers make. It will help unleash your full putting potential. Based upon my work in the testing and development of putters, along with my coaching of tour players, I have been recommending my players use a stiffer shaft in their putters for over 15 years. I can say without reservation, the stability shaft far exceeds any shaft available.” – Jim Mackay, President OnePutt Enterprises, Inc.
