Diamana™ RB

Diamana™ RB Overview

Diamana™ RB (Red Board) – the third profile in the most recent generation – is designed with all the traditional branding that made Diamana™ so beloved – including a return to the original 53/63/73/83 weight class designations – and all the engineering prowess and material innovation that made the brand dominant on tour.

Offering a slightly higher launch angle than BB, Diamana™ RB was engineered to promote ease of launch while also maintaining control down field. Diamana RB is a classic "Red Board” profile — not available since the 2nd Generation of Diamana — that features an active tip section while still retaining the same material technology package (see below) and low-torque control characteristics  as its lower 6th Generation launching counterparts.

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.

News & Reviews

Mitsubishi Launches Diamana™ RB to Complete the Diamana Lineup: Wed, Jan 08, 2025 — The Mitsubishi Diamana RB is the highest launching shaft in the lineup as well as the highest spinning. Even though the RB is the highest launching and spinning, it by no means is a “soft” shaft that only slower swing speed players will benefit from.
