KBS TGI Tour Graphite Iron Shaft (.370)
KBS TGI Tour Graphite Iron Shaft (.370)
Your Graphite Now Plays Like Steel
The KBS TGI Tour Graphite Iron Shaft is designed for golfers who want the lighter weight and vibration characteristics of graphite while retaining the control, stability and connected feel associated with a premium steel shaft.
Developed using the same foundational E.I. curve as the KBS Tour Steel Shaft, the TGI combines optimized weight and stiffness to provide dependable shot-making performance. Its progressive weight options help golfers find a profile that matches their swing speed, transition and preferred shaft feel.
This listing is specifically for the .370-inch parallel-tip TGI. Each shaft is supplied at a 41-inch raw length and must be tip-trimmed for its intended iron before being butt-trimmed to final playing length.

Who Should Play the KBS TGI?
The TGI is designed for golfers who want to move into graphite without losing the stable feel, shot control and predictable response they associate with a KBS steel iron shaft.
The .370 parallel-tip family ranges from a lightweight 50g Lite/A model to an 80g Stiff option, supporting a broad range of players. Professional fitting is recommended because weight and stiffness increase together throughout the TGI range.

Parallel-Tip Trimming Is Required
The .370 TGI is a single-length 41-inch raw shaft. The shaft must be tip-trimmed according to its intended iron position and then butt-trimmed to the required finished playing length.
Tip trimming can change how the shaft launches, feels and plays. Installation should be completed by an experienced club builder using the official KBS trimming instructions.
