Graphite Design Raune Iron Shaft (0.370" Parallel Tip)

Graphite Design Raune Iron Shafts — .370″ Tip (60g / 75g / 90g) Lightweight, tour-inspired graphite iron shafts built for effortless speed and a smooth, playable feel — available now at Grips4Less. 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 Raune .370″ Tip — Weight & Flex Options Model Flex Weight Torque Kick Point Launch Spin MSRP Raune 60g Regular 62.0g 4.2° Low/Mid Mid/High Mid/High $130 Raune 75g Regular 73.0g 3.6° Low/Mid Mid/High Mid/High $130 Raune 90g Stiff 93.0g 3.1° Mid Mid Mid $130 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.
