The SteelFiber i-series was born from the voices of PGA & LPGA players, pursuing the performance and comfort always demanded in the world of golf.
Its unique performance comes from the fusion of graphite and steel.
The design freedom and distance performance of graphite, combined with the stability of steel,
allows players to experience a more stable swing and greater distance.
SteelFiber is incredibly thin;
approximately 94km of fiber is wrapped around a single shaft.
Furthermore, AEROTECH's involvement has further enhanced its quality and reliability.
AEROTECH, which boasts a high usage rate in the American PGA & LPGA,
has become a member of True Temper Sports,
and with the addition of new brands, will offer optimal shafts to a wide range of golfers.
The SteelFiber i-series provides a new option for golf enthusiasts,
as a "third choice" following Dynamic Gold and Project X.
Simply put, an "iron combo set" is a setup that combines different models of irons within a single set.
In the past, it was common to "have the same model from 5-iron to PW," but in recent years, even among tour pros,
"easier long to mid irons, and emphasis on control for short irons"
has become the mainstream approach.
1. Why are "combo sets" so popular?
There are mainly two reasons.
These are "the evolution of ball performance" and "changes in green conditions."
Increased difficulty of long irons
Modern golf balls are evolving in a direction that suppresses spin to enhance distance performance.
As a result, with conventional muscle-back (01 series) long irons, even with a pro's head speed, it is becoming increasingly difficult for the ball to get airborne and stop on the green due to insufficient spin.
Role change from "hitting far" to "stopping"
For pros, 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 is a growing trend to combine highly forgiving models that feature thicker soles or hollow structures.
2. If you're building with PRGR? Recommended Combos
PRGR's 01-02 series is actually a lineup that is very easy to combine into combo settings.
Classic Athlete Combo: 01 × 02
・4-6 iron: 02 IRON (high trajectory and easy to hit far)
・7-iron to PW: 01 IRON (emphasizing control and feel)
Key points
Since the 7-iron of the 01 (32° loft) is combined with the 6-iron of the 02 (28°),
the loft progression is natural, and a combo setting with minimal difference in feel and no discomfort is possible.
