Graphite Design Raune Iron Shaft (0.355" Taper Tip)
Graphite Design Raune 105g Iron Shafts — .355″ Taper Tip
A firmer, faster-swinging graphite iron shaft built to length for a drop-in fit — 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 Raune 105g is the firmest, fastest-swinging build in the family, offered in a .355″ taper tip design in both Stiff and X-Stiff flex. Unlike the unitized .370″ models, the 105g ships pre-cut to ten discrete finished lengths (39.0″ down to 35.5″), so it installs straight in with no tip trimming required — just butt-trim to your final club length.
Key Features
- High-modulus, aerospace-quality carbon fiber construction for exceptional stability
- Graphite Design proprietary MSI (Material Stiffness Integration) design philosophy
- Firm butt, mid, and tip sections for a stable, low-spin feel geared toward faster swing speeds
- .355″ taper tip — insert straight in, no tip trimming required
- Mid launch and mid spin for penetrating, consistent ball flight
- Ten pre-cut finished lengths per flex (39.0″–35.5″) for precise, length-specific fitting
