Overview

The Graphite Design Raune (pronounced “Raw-nay,” derived from the Japanese word for “Aim”) iron shaft is engineered to deliver a uniquely stable, controlled feel to golfers of every skill level. Each Raune shaft pairs a high-modulus carbon fiber core for stability with a pitch-fiber outer layer, fine-tuned for optimized stiffness and feedback through impact. The result is a shaft that loads smoothly, releases predictably, and helps golfers find more consistency from swing to swing.

This .370″ tip, unitized family covers three progressively firmer builds — the 60g Regular, 75g Regular, and 90g Stiff — giving golfers a clear path to the right combination of weight and flex for their swing speed and tempo.

Key Features

• High-modulus, aerospace-quality carbon fiber construction for exceptional stability
• Graphite Design proprietary MSI (Material Stiffness Integration) design philosophy
• Progressive bend profile across the 60g, 75g, and 90g builds for a tailored feel at every weight
• .370″ tip OD with 4.0″ of parallel tip section for consistent, repeatable tip trimming
• Mid/high launch and mid/high spin (60g & 75g) or mid launch and mid spin (90g) to match a range of ball-flight needs
• 39.0″ raw (uncut) length — trim to finished club length per the tip trimming chart below

Available Weights & Flexes

Bend Profile

The Raune 60/75/90g lineup is built with a deliberately progressive bend profile — each step up in weight firms up the shaft from the tip toward the butt, letting golfers move up in stiffness without a jarring change in feel.
