Measurement and Method – TBAR Part 3

All flex measurements whether static or dynamic, are measured from the butt section of a golf shaft, with little or no attention being paid to the tip section. The results most of the time, can yield golf clubs of similar shaft flex, torque, head weight and swing weight, yet these golf clubs will have different feel, shot trajectory and/or dispersion; leaving you with the question, “what happened?” and “why”?… Read More…

The Art of Golf Shaft Measurement – TBAR Part 2

there are many variables that contribute to fitting a player, some of which are more important than others: It is all a sea of grey.

Our quality golf shafts, through advance design, materials, and manufacturing processes, are made to the most exacting tolerances. The result is a golf shaft that yields a consistent flex time after time. A club maker can always depend on Penley to deliver a consistent, high quality product every time.

All new Penley golf shafts are primarily designed to create the optimum club for the player, including the Touring Pro. Our design yields a shaft with precision and control like no other, it avoids the compounding effect of a players’ miss-hit and offers more greens in regulation.

When you order an ‘S’ flex golf shaft (or any other desired golf shaft flex), you receive an ‘S’ flex not almost an ‘X’ or almost an ‘R’. All Penley shafts are designed, machined and spec’d as a specific defined shaft flex.

With the development of Penley’s new performance design & manufacturing processes such as the TBARTM (Tip to Butt Aspect Ratio) algorithm and ZONE FLEXTM Characterization, Penley golf shafts are a level above ALL others. We are considered by many top club makers and players as the highest performing and most exacting golf shafts available in the industry for distance, accuracy and consistency.

Carter Penley’s high quality golf shafts are known by Long Drive Championship players and PGA players worldwide.  Since  2010,  Penley had over 100 shafts in play and have placed in the following Tournaments using the ET2 and the Hybrid Heater2:
