CRAZY Crazy STI-80 Carbon Steel Fusion Iron Shaft: Operability, Rebound Feel, Distance-Seeking Model. Shaft sold separately (re-shafting only).

The CRAZY DEAD I-100 STINGER is a professional-grade iron shaft developed for competitive players. Its main feature is its "tip-reinforced design," which prevents loss of impact energy, stabilizes the club head, and provides excellent stability even with sharp swings.

It overturns the common belief that "light equals unreliable" and "heavy equals difficult to swing" with an exquisite balance design that ensures ease of swinging while maintaining a sense of weight. This makes it ideal for those who have struggled with inconsistent ball flight or competitive players who want to improve swing reproducibility.

It also excels in directional and distance stability, allowing for consistent swing feel from short to long irons. With the feel and operability trusted by professionals, this shaft will give you confidence in shots aimed at the green.

For all golfers who seek "precision" and "feel," experience CRAZY's high-performance carbon shafts.
