The Fujikura FUJIKURA AIR SPEEDER NEW AIR SPEEDER DR is the latest shaft designed to provide golfers with the best performance. This model incorporates VTC (VARIABLE TORQUE CORE) technology, also found in the SPEEDER NX series, to achieve high launch and high ball speed in drivers. Furthermore, with the addition of three flex options, more precise fitting is now possible.
VTC technology meticulously controls torque distribution, tightening torque at the tip and butt to achieve high initial velocity and high launch. Partial multi-hoop technology optimizes the lamination technique of hoop layers to suppress crushing from the mid-section to the butt. This technology aims to provide appropriate flexibility at the tip, making it easier for the ball to launch and optimizing spin rate.
Furthermore, the driver uses an ultra-low resin carbon sheet, "RC20% prepreg," which maximizes the carbon fiber ratio to achieve stronger flex and return. The EI design enhances bending rigidity in the mid-section, stabilizing the amount of flex during the swing, thereby suppressing the ball from losing power upon impact. This achieves both easier ball launch and increased ball speed.
This shaft optimizes the flow from driver to iron and unifies the swing feel between clubs, enabling optimal shaft fitting.
An "iron combo set" simply refers to a club setup that combines different iron models within a single set.
While it used to be common to "match the same model from 5-iron to pitching wedge," in recent years, among tour professionals, the prevailing approach has been to use:
"Easy-to-hit long to mid-irons, and short irons focused on workability."
1. Why are "combo sets" gaining popularity?
There are two main reasons:
These are "the evolution of ball performance" and "changes in green conditions."
Increased difficulty of long irons
Modern golf balls have evolved to suppress spin in order to improve distance performance.
As a result, with conventional muscle-back (01 series) long irons, even professional head speeds struggle to get the ball up, and there are increasing cases where insufficient spin makes it difficult to stop the ball on the green.
Shift in role from "distance" to "stopping"
For professionals, long irons (4-5 iron) are not just clubs for gaining distance.
They are clubs for aiming at the pin with a high trajectory and stopping the ball firmly on the green.
Therefore, for long to mid-irons, there's a growing trend to combine models with high forgiveness, featuring designs with thicker soles and hollow structures.
2. Recommended combos with PRGR?
PRGR's 01-02 series is actually a lineup that makes combo setups very easy to build.
Classic Athlete Combo: 01 x 02
・4-6 iron: 02 IRON (high launch and easy distance)
・7-iron to PW: 01 IRON (focus on workability and feel)
Key Points
Since the 7-iron of the 01 (loft 32°) is paired with the 6-iron of the 02 (28°),
the loft progression is natural, and a combo setup with minimal difference in feel and no discomfort is possible.
