Mitsubishi Rayon Diamana BF-Series Shaft

Introducing the next-generation Blue Board shaft by Mitsubishi - The Diamana BF Series Blue

Continuing the same tradition of the original blue series the new BF blue board shaft is known for a tight dispersion combined with a smooth feel. Mitsubishi started by reinforcing the tip of the shaft to improve impact efficiency ball velocity. Mitsubishi utilized their new Superelastic DIALEAD material to particular areas such as the tip and butt section. What this does is improve the maneuverability of the ball at the players will. The tip section has also been reinforced with their new MR70 high strength carbon fiber mixed with boron fiber to improve elasticity without hindering energy loss transferred to the ball. The result is more distance with better direction and workability making the overall shaft experience both stronger and more flexible at the same time.

Reexamining the raw material fibers and the manufacturing process of the original blue board allowed Mitsubishi to create a new carbon fiber material possessing both improved elasticity and strength, something which has been hard to achieve in the past. Approximately 20% strength improvement and 10% elasticity improvement compared to Mitsubishi Rayon's past products. Now available for pre-order in the TSG ProShop with an August 5th Ship Date!
