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 combining 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,
with approximately 94km of fiber 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,
is now 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 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 iron models within a single set.
While it used to be common to use the same model from "5-iron to PW," in recent years, among tour pros,
the mainstream approach has become to use "forgiving long to mid irons, and short irons focused on workability."
1. Why are "combo sets" so popular?
There are mainly two reasons:
They 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 with a pro's head speed, it has become increasingly difficult to get the ball up and stop it on the green due to insufficient spin.
Role change from "hitting far" to "stopping"
For pros, long irons (4-5 irons) are not just 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 an increasing trend to combine highly forgiving models that feature thick sole designs or hollow structures.
2. If you're building a PRGR combo? 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 (focus on workability 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.
