The Mitsubishi Diamana BB – Blue Board – is the driver shaft for golfers who want a modern tour shaft with mid launch and spin and an unusually smooth, fluid feel. BB is the second profile in the latest Diamana generation and brings back the classic Diamana style, right down to the original weight designations – with the surfboard-inspired design that made the shaft an icon.
Beneath the surface is the latest in Mitsubishi carbon fibre development: ultra-stiff fibre in the butt section, high-modulus fibre in the angle plies and a proprietary resin that makes the shaft both stronger and livelier in feel. The result is tour-level stability and energy transfer, from the maker behind more than 700 tour wins since 2004.

Super high-modulus fibre in the butt section delivers maximum stability and energy transfer – more of your swing speed goes into the ball.

High-modulus fibre in the shaft's angle plies lowers torque without adding weight. The clubhead stays stable through impact for straighter drives.

Mitsubishi's proprietary resin system increases the shaft's strength and durability while more carbon fibre delivers the smooth Diamana feel.
