Overview
Shipping and Returns
RAUNE Means “Aim”
Premium Graphite Iron Performance
Graphite Design RAUNE—pronounced “Raw-nay”—uses high-modulus materials in its core for stability and pitch fiber in the outer layer to optimize stiffness and feel.
The .370" unitized lineup is offered in three distinct profiles, allowing golfers to choose lighter, higher-launching performance or a heavier, more stable mid-flight option.
Available options are RAUNE 60 Regular, RAUNE 75 Regular and RAUNE 90 Stiff. Graphite Design also manufactures a RAUNE 105 constant-weight .355" taper-tip iron set, but that model is not included in this product listing.

Advanced Material Construction
High-Modulus Core
Premium high-modulus carbon-fiber material forms the shaft’s core to provide stability, efficient energy transfer and consistent performance.
Pitch-Fiber Outer Layer
Pitch fiber is applied to the outer layer to optimize stiffness and contribute to RAUNE’s responsive, premium feel.
Material Stiffness Integration
Graphite Design’s proprietary MSI philosophy strategically integrates different material and stiffness characteristics to balance stability, trajectory, control and feel.
RAUNE Iron Bend Profiles
The RAUNE family becomes progressively firmer as shaft weight increases, allowing golfers and fitters to select the desired balance of launch, spin, feel and stability.

| 96–105 mph | Stiff | RAUNE 90 S |
