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 distinguishing feature lies in the unique performance achieved by fusing graphite and steel.
The design freedom and distance performance of graphite, combined with the stability of steel, allow players to experience more stable swings and greater distance.
SteelFiber is incredibly thin, with approximately 94km of fiber wound into a single shaft.
Furthermore, AEROTECH's involvement has further enhanced its quality and reliability.
AEROTECH, boasting a high usage rate in the American PGA & LPGA, has become a part of True Temper Sports,
and with the addition of this new brand, they now offer optimal shafts for a wider range of golfers.
The SteelFiber i-series provides golf enthusiasts with a new option,
as a "third choice" following Dynamic Gold and Project X.
An "iron combo set" simply means combining different iron models within a single set.
While it was once common to "have the same model from 5-iron to PW," in recent years, among tour pros,
"easy long-to-mid irons and short irons prioritizing maneuverability"
has become the mainstream approach.
1. Why are "combo sets" trending?
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 to enhance distance performance.
As a result, with conventional muscle-back (01 series) long irons, even with a pro's clubhead speed, it's becoming more common for the ball to not get airborne easily and lack spin, making it difficult to hold the green.
Role change from "hitting far" to "stopping"
For pros, long irons (4-5 iron) are not just about 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,
it's becoming more common to combine highly forgiving models that feature thicker soles or hollow structures.
2. What if you're building with PRGR? Recommended Combos
PRGR's 01-02 series actually offers a lineup that is very easy to create combo settings with.
Classic Athlete Combo: 01 × 02
・4-6 iron: 02 IRON (easy to hit with a high trajectory)
・7-iron to PW: 01 IRON (prioritizing maneuverability and feel)
Points
Since the 7-iron of the 01 (loft 32°) 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.
