The SteelFiber i-series, born from the voices of PGA & LPGA players, pursues the performance and comfort constantly demanded in the world of golf.
Its distinguishing feature lies in the unique performance achieved by combining graphite and steel.
The design freedom and distance performance of graphite, coupled 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, which boasts 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 will provide optimal shafts for a wide range of golfers.
The SteelFiber i-series offers a new choice for golf enthusiasts, serving as a "third option" 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.
While it was once common to have "the same model from 5-iron to PW," in recent years, among tour pros,
"easier long to mid-irons, and short irons focused on workability"
has become the mainstream approach.
1. Why are "combo sets" so popular?
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 reduce spin to increase distance.
As a result, with conventional muscle-back (01 series) long irons, even with a pro's head speed, it's becoming more difficult for the ball to get airborne and to 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 targeting the pin with a high trajectory and stopping the ball firmly on the green.
Therefore, for long to mid-irons,
there is an increasing trend to combine highly forgiving models that feature thicker soles and hollow structures.
2. What if you're building with PRGR? Recommended combo
PRGR's 01-02 series is actually a lineup that makes combo settings very easy to assemble.
Classic Athlete Combo: 01 × 02
・4-6 iron: 02 IRON (easy to hit high and far)
・7-iron to PW: 01 IRON (emphasizing workability and feel)
Key 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.
