Diamana™ B-series, the third generation Diamana™ in the "Blue Board" series

This new Diamana™ B-series, with its new ion plated cosmetic, features material from Mitsubishi Plastics Inc. (DIALEAD™) and the latest prepreg (Tough-QURE™) advancement from our partners within the Mitsubishi Chemical Holdings Corporation (MCHC) Group. The new B-series also becomes the first shaft by Mitsubishi Rayon to use 3G M.D.I. technology to deliver the tour-proven performance and superior stability players of all abilities have come to expect from the Diamana™ brand.

In 2009 Mitsubishi Rayon introduced the original Multi-Dimensional Interlay (M.D.I.) Technology featured in the Diamana™ Kai'li™ Series - the second generation Blue Board. This M.D.I. Technology allows Mitsubishi Rayon to layer thin carbon fiber sheets in multiple directions along the entire length of the shaft, providing our engineers precise control over stiffness and stability throughout the shaft. This same M.D.I. technology was used in subsequent years to develop and launch the rest of the Second Generation Diamana™ Series, Diamana™ 'ilima™ in 2009 and Diamana™ 'ahina™ in 2010, and most recently to develop the Diamana +PLUS™ Series.

3G Multi-Dimensional Interlay (M.D.I.) Technology -
Working with our partners in the MCHC Group, Mitsubishi Rayon has now developed the next generation M.D.I. Technology - 3G M.D.I. featuring DIALEAD™. The 3G M.D.I. Technology featuring DIALEAD™ allows our engineers to fine-tune both the E.I. Curve (Bend Profile) and the G.J. Curve (Torsion Profile) for the Diamana™ B-series to increase the overall "controllability" and minimize "ovaling" in this new series of shafts.

The Diamana™ B-series profile represents the next evolution in MRC'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).

Diamana™ B-series is available in the following weights and flexes:

50 R,S,X
60 R,S,X
70 S,X
80 S,X
