The B-series profile represents the next evolution in MCA GOLF's signature "smooth" bend profile offering "balanced" stiffness on both ends of the shaft with a slightly "stiffer" mid-section. The profile was first made popular in 2005 with the debut of the initial Diamana™ S-Series (Blue Board).
Its sheer power is a tribute to it being made with strong “pitch” carbon fiber. Building on the success of our signature smooth profile embodied in our Diamana™ Kai'li™, it maximizes energy transfer by stabilizing the butt section.

Technology
DIALEAD™ Pitch Fiber
The Third Generation Diamana™ Series 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 Rayon, or our trusted partners, giving us precise control over every step of the process.
Tough-QURE™
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.
3G Multi-Dimensional Interlay (3G M.D.I.)
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.
