Mitigating Unwanted Flex and Twist
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
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.
Introducing Stability Shaft
Stability vs. Steel
The heel and toe smoothly increase velocity until center impact.
- Causes almost no oscillation
- Evidence of how much more stable the Stability shaft is
- Causes wild oscillation
- Evidence of how weak and unstable a steel putter shaft is, even on center strikes
