Stability ZNE® Wedge Shafts from Breakthrough Golf

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.
