DIAMANA BF 70

The Diamana™ BF-series represents the next generation version of MRC’s signature “smooth” bend profile. The new BF-series, like its most recent predecessor the Diamana™ B-Series, incorporates high-strength DIALEAD™ Pitch Fiber by Mitsubishi Rayon into the butt-section of the shaft, adding unprecedented strength and control during shaft loading and unloading.

The new Diamana™ BF-Series also incorporates for the first time a new hybrid prepreg developed by the engineers at Mitsubishi Rayon. This new prepreg combines boron fiber and Mitsubishi Rayon’s latest carbon fiber innovation MR70. Mitsubishi Rayon’s MR-70 by is 20% stronger and has 10% higher modulus than conventional carbon fibers. Strategically positioned in the tip-section of the shaft this hybrid prepreg provides unprecedented strength and stability at impact.
