Mitsubishi Rayon’s new Diamana BF-Series shafts

Published

on

In 2005, Mitsubishi Rayon Composites introduced a mid-launching shaft that became one of the most popular shafts in history. Officially it was known as the Diamana S-Series, but golfers around the world came to know it as the “Blue Board.”

Diamana classics kept coming from MRC — the company later popularized a D-Series, or “White Board” shaft that offered a lower trajectory, as well as an M-Series, or “Red Board” shaft that offered a higher trajectory. Eleven years and many generations later, however, the Blue Board, with its mid trajectory and smooth bend profile, continues to be the company’s most popular model.

This fall, Mitsubishi Rayon has launched the fourth generation of its most premium Diamana Blue Board profile, which it’s calling the BF-Series. The new shaft is designed to replace the company’s third-generation (B-Series) Diamana Blue Board shafts.

Like the B-Series shafts, the new BF-Series shafts use Dialead Pitch Fiber in the butt section of the shaft, which is stronger than carbon fiber. It’s said to provide stability during the loading and unloading process in the transition of the swing, improving energy transfer.

For stability and strength in its tip section, MRC has introduced a new hybrid prepreg that’s never been used before. The hybrid includes boron and a new material called MR-70, which was first introduced in Mitsubishi Chemical’s aerospace sector. Boron adds strength to the prepreg, and the MR-70 material is 20 percent stronger and 10 percent higher modulus than standard carbon fibers, according to MRC.

For a laymen’s visual of what a prepreg is, think of a Fruit Roll-Up (click here for a reminder). Except instead of candy, the flat material is made of carbon fiber, boron, MR-70 and resin. That material is then rolled in specific directions around a mandrel, and baked in a really hot oven to fuse it all together.

The combination of strategically placed materials is designed to make the shaft profile smoother throughout the swing. The result? A slightly lower launch than the B-Series, with more stability, and — if it’s a fit for your swing — a tighter dispersion and more distance.

    GAwddammit. Not again. What’s with the current trend of extremely high torque for mid-launch shafts at lower weights? Whatever happened to the days of very low torque at lighter weights?

    No would think not, simply stiffer.
    Tipping is usually never done at he OEM level, but more at the build stage to tweak launch and feel around tip stiffness.

Published

on

Cleveland Golf has introduced Cleveland Launcher UHX irons, which incorporate hollow back long irons with cavity back short irons.

The unique approach looks to provide maximum distance and forgiveness in the long irons (4- 7-irons) through lower and deeper weighting in the hollow back construction while focusing on precision and control from the 8-iron to PW with a cavity back design in this addition to the 2020 Cleveland iron lineup.

The new additions also contain a high-strength, HT1770M variable steel face insert in each long iron. According to the company, improved mass distribution in the face insert is designed to deliver higher ball speeds and more distance on each shot.

Speaking on the new Launcher UHX irons, Director of Engineering, Research and Development at Cleveland, Dustin Brekke stated

“This combination of cavity back and utility irons into one set offers the perfect blend of distance and accuracy. A new variable face pattern delivers more distance due to hotter faces with better mass distribution.”

Both the hollow and cavity back irons feature a V-Shaped Sole which is designed to offer both improved speed retention and forgiveness through improved turf interaction. The company’s Tour Zip Grooves and enhanced Laser Milling aim to provide maximum spin on each Launcher UHX short iron.

Arriving in both left and right-handed options, Cleveland’s Launcher UHX Irons officially launch on October 4 and are priced at $799.99 MAP for a seven-piece steel set and $899.99 MAP for a seven-piece graphite set.

“These irons allow game improvement players the ability to get the ball into the air better than any iron on the market. Now with a thinner, hotter face, the Launcher HB Turbo Irons give you a half club more distance over the previous generation.”

The irons feature a redesigned HiBore Crown, which pushes the center of gravity low and deep within the base, a placement which is designed to allow golfers to launch their ball higher.

The clubs also contain progressive shaping throughout, as the brand seeks to provide players with a smooth transition by offering maximum forgiveness on long irons to optimal control on short irons.
