Mitsubishi Chemical Diamana BB Driver/Wood Shaft

The Mitsubishi Chemical Diamana BB (Blue Board) is a sixth-generation evolution of one of the most respected shaft lines in premium golf, bringing back the classic branding and original weight class designations that made the Diamana name so beloved on tour, built on a platform of modern material engineering that makes the BB arguably the best the series has ever been.

The BB is the mid-launching profile in the latest Diamana generation, sitting between the lower-launching WB (White Board) and the higher-launching RB (Red Board). It is engineered to deliver a smooth, incredibly refined feel that tour players and serious amateurs have come to expect from the Diamana line, while also offering the kind of stability and energy transfer that modern high-MOI heads demand.

To maximise energy transfer through impact, super high-modulus 80-ton Dialead Pitch Fiber is used in the butt section. High-modulus 46-ton fibre is used in the shaft's angle plies to lower torque and improve stability without adding weight. And Mitsubishi Chemical's proprietary Xlink Tech resin system ties it all together, increasing the strength and durability of the shaft while driving carbon fibre volume up for better feel.
