FULL DESCRIPTION
The Mitsubishi Diamana RB is a high launch, mid-high spin driver shaft — the highest-launching model in the current Diamana generation and the only Diamana profile built around an active tip section. It features a medium-plus handle for smooth loading, a medium-plus mid section that provides controlled stability through the downswing, and a medium tip that allows the head to work actively at impact to produce the elevated ball flight the RB is built around. Mitsubishi engineered the RB with the same premium material package as the rest of the Diamana 6th Generation lineup — 80-ton DIALEAD pitch fiber in the butt section, high-modulus fiber angle plies to reduce torque, and Xlink Tech resin — while specifically tuning the bend profile to promote ease of launch and more carry distance. Best suited for swing speeds between 85 and 105 mph who want the smooth, classic Diamana feel with a noticeably higher and more workable ball flight.
Compared to the Diamana BB (mid launch, mid spin), the RB produces a meaningfully higher ball flight with slightly more spin — making it the better fit for players who find the BB doesn't generate enough carry height or who need a more workable, higher-launching trajectory. Compared to the Diamana WB and Diamana PD (both low launch, low spin), the RB is at the opposite end of the Diamana spectrum — if you've been fit into a Diamana and told you need more height, the RB is where to look. Compared to the Diamana GT (low-to-mid launch, ultra-stiff handle), the RB has a softer, more forgiving overall profile suited for players with a smoother or more moderate tempo.

Key Features Include:
- 80-ton DIALEAD Pitch Fiber in butt section to maximize stability and energy transfer
- High modulus 46-ton fiber in angle plies to lower torque without increasing weight
- Xlink Tech™ Resin System to increases the strength and durability of the shaft
Who should play it? Golfers looking to generate a little more speed through a shaft that has a little active tip section while also maintaining control down field.
Questions & Answers
Have a Question?
-
How does the RB compare to the older Red Board models like the RF or M+?
The older Red Board shafts like the RF and M+ had a very obvious kick at the bottom of the swing — you could feel the tip snap through impact, which was great if your timing was right but punishing if it wasn't. The new RB is much smoother. The tip is still active, but it loads and unloads gradually through the whole swing instead of kicking all at once. It's easier to control, doesn't balloon on faster swings the way some of the older ones did, and the overall feel is more premium. If you played a Red Board from 10 or 15 years ago and liked the concept but not the harshness, the new RB is worth a fresh look.
