DISCOVER YOUR TRUE NATURE
Introducing


Woods Shafts
The Miyazaki 4-Quadrant system featured on the all-new CODEX Shafts means a more precise fitment for more power and more control.
CODEX MODELS
FROM ALL, ONE
Tens of thousands of golf shafts from the most popular makes and models were analyzed by Miyazaki engineering. Those learnings resulted in CODEX; a shaft performance genome that gives us a blueprint when we go to make a new shaft.
This four-digit International Flex Code (IFC for short) notates Flex Quadrants. By breaking down a distinctive flex for these specific regions, CODEX produces the exact launch, spin, and feel that our engineers are after.
The Four Quadrants
From butt to tip, the four numbers of the IFC correspond to these locations along each shaft.


First Number1st No.
36" from tip

Second Number2nd No.
26" from tip

Third Number3rd No.
16" from tip

Fourth Number4th No.
6" from tip
BUILT BETTER

Superior Carbon
Japanese carbon is world renowned for its lightweight strength. Our proximity to leading composite scientists guarantees us the best combinations of components so that you can have a better shaft.
Stronger Design
By rotating our Hoop Layer 90°, we add strength without sacrificing consistency. This lets us load extra potential energy on the downswing and ensure stability and consistency through impact.

*For illustrative purposes only. Actual Hoop Layer location may differ.
Voidless Construction
Most shafts have microscopic air pockets between their layers of graphite. Our unique manufacturing proces eliminates these voids to increase strength and durability.

*Only part of shaft depicted.
Understanding the Numbers
They correspond to our own in-lab measurements of all past and current in-market shafts, which we’ve aggregated and defined as:
9 – Market Extreme Stiffness
7 – Normalized X Flex (X-Stiff)
5 – Normalized S Flex (Stiff)
4 – Normalized R Flex (Regular)
3 – Normalized A Flex (Senior)
1 – Normalized L flex (Ladies)
0 – Market Extreme Softness


LOW LAUNCH
High Kick Point
As cooler temperatures turn moving water into solid ice, KORI (ice) crystallizes your control of trajectory, ball flight, and distance. Its low, penetrating launch, low spin, and high kick point are perfect for confident players with strong swing speeds who demand complete control.
