Breakthrough Golf Technology
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.

The absolute best place to order club making parts, especially adapters. The crew at Billy Bob's is extremely knowledgeable, and stand behind all of their products. I will never use eBay, Amazon, or GolfWorks for ordering specialty parts for clubmaking again. The customer service at Billy Bob's and the quality of the product is above all others for aftermarket building materials and they will treat you like family if you ever have any questions or concerns. On multiple occasions I have had a problem or question and they always pick up the phone with helpful answers and even have offered full replacements of their product when I lost a part. The best ever at what they do and I will never go anywhere else for my clubmaking materials.
