The majority of our material technologies are developed in-house at our labs in Toyohashi, Japan or within the Mitsubishi Chemical Holdings Group. Over the years, we have created thousands of proprietary materials and processes that together create the finest golf shafts in the world. Performance without Compromise.
Some of the technology innovations we include in our products:
The “braiding” technology using Tow Prepreg is incredibly resistant to twisting and ovaling and creates a shaft with no spine, so the shaft performs more consistently than a shaft made with traditional sheet prepreg.
Diamana™ features our latest prepreg with DIALEAD® Pitch Fiber for outstanding strength and energy transfer with a minimum of shaft deformation. While more costly and difficult to manufacture, the pitch fiber we are using is much stronger than traditional carbon fiber. All prepreg used in our shafts is developed and produced by Mitsubishi Chemical, or our trusted partners, giving us precise control over every step of the process.
The Ion Plating process creates a sophisticated, premium finish that cannot be achieved just by applying paint. The shaft is put into a vacuum chamber where chrome or silver alloy ions are fused to the shaft. It’s a more costly, time consuming process but it creates a stunning finish that we think is worth the extra time.
Our Low Resin Content (L.R.C.) prepreg, with up to 15% more carbon fiber and 13% less resin than traditional prepregs allows us to create a higher density of carbon fibers without adding additional weight. The Result: Added strength with enhanced feel.
A major advancement when it was introduced in the original FUBUKI™ profiles, Modulus Differential Technology (M.D.T.) allows us to take fibers with different strength and performance traits and combine them to create extremely precise “performance zones” along the shaft. By fine-tuning fiber length and placement, we can dial in very specific launch and spin characteristics.
Multi-Dimensional Interlay (M.D.I.) Technology allows us to layer carbon fiber in different directions along the shaft, to create very specific bend and torsion characteristics for the desired shaft performance. This gives us precise, pinpoint control over stiffness, stability and flex in any profile, while reducing shaft deformation at impact.
Our P.N.C. Stainless Steel Mesh Technology was first used in the FUBUKI™ K-Series. A layer of ultra-thin yet strong steel webbing is integrated into the core of the shaft. The mesh acts as a truss—adding strength and minimizing shaft deformation in all directions.
Titanium Nickel (TiNi) Wire is a premium elastic wire that immediately springs back to original shape when stretched. Integrating TiNi with carbon fibers in the tip-section allows energy to be loaded and unloaded with great efficiency when the wire stretches, while providing extra strength and stability to the tip. This allows for tighter shot dispersion, even for players with a high swing speed.
Our Tough-QURE™ prepreg contains resins that cure harder and two times faster than traditional resins, for superior strength and stability. Our proprietary Block Copolymer Technology allows Tough-QURE™ to link “softer” (more elastic) polymers and “harder” (more durable) polymers together, creating a prepreg that significantly strengthens the shaft without sacrificing feel.
Instead of being made with a traditional prepreg sheet, the OT™ Iron shaft employs a new material for golf shafts called Tow Prepreg that contains carbon fibers arranged in super-strong “bundles” -- much the way a steel cable is made. These bundles are impregnated with resin to create the Tow Prepreg, and then woven together like a braid.
A major innovation for 2015 from the labs in Toyohashi, Japan is our use of resin-infused prepreg with tungsten powder, a very heavy and dense powder. Wrapping tungsten-infused resin sheets in the butt-section moves the center of gravity towards the butt of the shaft, without making the shaft more rigid. The higher balance point means greater flexibility in building the shaft at any length while keeping the same effective feel.
Our expertise in creating thousands of versions of carbon fiber and resin combinations gives us the ability to create unique high-performance materials designed to deliver exactly what our engineers require to make our ultra-lightweight, high-performance shafts.
Our Variable Torque system optimizes performance by targeting shaft torque and frequency. Players of all abilities can benefit from a torque and frequency designed to meet their swing speeds.
MRC's 3G Multi Dimensional Interlay (M.D.I.) has been the foundation of the new Diamana™ Series, beginning with the B-Series in 2012. Used in the butt section, it includes thin, high-modulus and ultra strong DIALEAD™ prepreg utilizing pitch fiber instead of traditional carbon fiber, which gives us more precise control over material usage and placement. This helps us optimize bend and torsional profiles, and prevents deformation while increasing overall control. Oriented in the hoop direction, the DIALEAD™ decreases ovaling in the downswing and transfers energy more efficiently to the ball at impact.
A Carbon Fiber/DuPont™ Kevlar® (CK) woven material; featuring Mitsubishi Chemical carbon fiber has been strategically placed under the hands to increase the strength and stability in the butt-section of the shaft in addition to providing superior feel and feedback throughout the swing.

By using innovative materials and creating slightly thicker walls toward the butt-end of the shaft we raised the balance point of the shaft which creates the potential for lighter swing weights, increased head-speed and distance.
Specifically designed and developed by Mitsubishi Chemical for high-performance applications, MR70 is an innovative new carbon fiber material that is 20% stronger and has 10% higher modulus than conventional materials.
Boron Fiber is equivalent in stiffness to high modulus carbon fiber with superior compression strength. As a result, Boron Fiber is often utilized for structure reinforcement most notably in military applications.
Mitsubishi Chemical’s bi-axial woven material featuring ultra thin spread tow fiber delivers greater strength in compression due to reduced fiber bulking. Our thinner woven materials can achieve a superior strength-to-weight ratio vs. traditional carbon fiber woven prepregs due to more fiber, and less resin.
The Straight Flight Weighting (SFW) System improves ball flight. As a shaft gets lighter, it becomes more difficult for the golfer to square the club face or turn the club over through impact, especially a driver. The effect becomes noticeable as shafts start weighing less than 60 gram. Thus, SFW is designed to help the golfer turn the club over easier through impact, which in turn straightens a slight fade or promotes a slight draw. A short section of tungsten weighted prepreg is precisely placed under the lower end of the shaft’s grip area to produce the effect.
Inside a vacuum-sealed chamber, the fiber is coated with aluminum vapor. This AV fiber adds stability, to help achieve the desired EI target. And the weave is tighter and thinner than the previous CK material, which helps prevent shaft ovaling.
A unique Metal Mesh Technology (MMT™) made from individually braided strands of 304 Stainless Steel – is integrated into the shaft’s prepreg layers towards the tip. This improves density and stability, while also allowing for thinner overall composite wall construction.
