DESIGN DRIVERS

The Penley Fairway Wood, also known as the ‘Platinum’ or the ‘Pt2’, is a standalone Fairway wood shaft- not a wood driver that is simply cut down to be made into a ‘fairway’. Each model is a unique design of its own with different mechanical and physical properties beyond a cut down driver. The Penley Fairway wood comes in 3, 5 or 7 wood.

The TBAR (Tip to Butt Aspect Ratio)

By analysis Penley determined that 60% of most golfers fall within flex range ‘1’ of the each and separate specific golf shaft flex ranges. ‘1’ is the center (1/3) of the full flex range (yellow dotted lines, 3-7). Penley tolerances are typically held to ~30%-40% of industry standards.

The shaft industries standard flex range is dynamically much larger and in many cases overlaps corresponding flexes. This is why some players who may need to build a backup club, or a replacement shaft for their club ends up finding out that the backup or or replacement shaft doesn’t feel or play the same as the first shaft model.

All Penley shafts are designed primarily to meet the 1 (mid-range) of each shaft flex. This  ‘1’ range is denoted  as A1, R1, S1, X1, 2X1 & 3X1 – etc and fit approximately ~60% of players.

Flex range and Zone flexes are determined by Penley’s TBAR™ (Tip to Butt Aspect Ratio) algorithm and are somewhat infinite vs. the long time excepted flex terminology.

To quantify Zone Flex Characterization, Penley has selected eight specific zone flexes outside of a predetermined flex range denoted numerically as ‘1’ (Penley’s Std. Range ‘1’) of each defined flex range i.e. ‘L1’, ‘A1’, ‘R1’, ‘S1’ and ‘X1’ and so on.

All shafts are designed primarily to meet the Z1 (mid-range).

For those that need a a different, more specific tuned shaft for their needs (such as higher/lower launch), review the Zone Flex Characterization Chart or Contact Penley.
