X‑link Tech

A new matrix resin technology that optimizes composition to form a rigid cross‑link structure. Enhances molding properties by up to 14% in strength, 15% in modulus, and 8% in strain-to-failure compared to conventional resins—unlocking MR70’s full potential.

Consistent Feel Design

Minimizes weight differences and butt-diameter variation between flexes in same weight class, and butt diameter differences across 40–80 g specs. Reduces sensory mismatch between weights/flexes, enabling smoother set-up from drivers to fairway woods.

Braiding Method

Unlike conventional carbon shafts made from pre‑impregnated sheets wrapped cylindrically, the OT™ iron uses resin-impregnated carbon fiber bundles assembled manually with proprietary toe-preg prepreg. This suppresses unwanted deformation and leads to stable head behavior through the impact zone.

PRECISION CRAFTED

Manufacturing precision ensures each shaft is managed to ±1 g weight variance and ±1 cpm frequency variance.

New Tip Technology

Optimizes tip torsion alignment to enhance swing stability from top through downswing for large-head/high‑MOI clubs, delivering efficient energy transmission during impact.

SPEEDMESH TECHNOLOGY

Featuring a micro stainless steel mesh that is 75% lighter and thinner than conventional materials, embedded between the carbon fiber layers. Its superior restoring force allows the shaft to recover rapidly from deformation during the swing, promoting exceptional stability and a consistently smooth, controlled feel.

MR70™

A breakthrough carbon fiber balancing stiffness and strength by reengineering precursor and resin processes. Offers ~20% higher strength and ~10% higher modulus vs. previous grades.

BoronFiber

High‑reinforcement boron fiber used where rigidity and reinforcement are prioritized—e.g. aerospace or high-performance fishing rods.

1K Weave

Fabric built from single-filament bundles (1K) providing dense, flexible weaving. Offers high formability, precision in modeling, reduced creep, and efficient reinforcement with minimal resin usage.

Tungsten Prepreg

High‑density tungsten‑loaded prepreg enables optimal weight distribution, delivering smooth stability through finish without stress.

DIALEAD™

Lightweight, high-modulus pitch‑based carbon fiber used in aerospace; its low thermal expansion ensures dimensional stability for superior reinforcement effect.
