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.
