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.

Odyssey Tri-Hot 5K lineup now includes mallets

Published

on

What you need to know: In January 2022, in the name of creating a blades with the MOI of mallets and forward CG, Odyssey threw everything at the wall with the Tri-Hot 5K family of blade putters: stainless steel, tungsten, 6061 aircraft grade aluminum. A year later, the company is bringing the same technology package to mallets with the Rossie and Seven models. The Tri-Hot 5K lineup now stands at seven putters (four with multiple necks).

2023 Odyssey Tri-Hot putters: Features and technology

Engineers applied the “Tri-Hot formula” utilized in blade putters in 2022 to move CG forward and raise MOI for a more forgiving mallet design — and a 5,000 IZZ inertia level (hence “5K”). Golfers will see improved speed and spin control, as well as consistency on off-center hits, according to the company, resulting in golf balls that finish closer to the hole when sub-optimally struck.

Stainless steel front: Odyssey touts the side-spin reducing capabilities of the 303 stainless steel hosel and face area for off-center putts. Tighter dispersion and putts that a more likely to go in results. Acting in a complementary fashion, the rear of the mallets are milled for tighter shape and weight tolerances that allows the CG to remain forward.

Tungsten front weights: Up to 120 grams of tungsten is positioned behind the face in the heel and toe sections of the putter heads. The resulting forward CG improves roll and increases inertia.

Interchangeable front weights: Available in 5, 10, 15 and 20 grams to dial in head weight and performance.

White Hot insert: 2023 Tri-Hot 5K putters add the iconic two-part urethane White Hot insert, which was originally developed using the same material as Callaway’s Rule 35 golf ball. White Hot, with its “firm but soft” properties has been a long-time favorite of Callaway staffers and recreational golfers. According to Callaway, “They’ve been asking for us to bring these technologies back and we’ve listened.” Can’t argue with that.

Stroke Lab shaft: The newest generation of Callaway’s multi-material Stroke Lab shaft features a shortened steel section and reduced weight (seven grams). Additionally it is stiffer. All of this leads to more stability and consistency.

Additional model details

Full lineup details — and who they’re for — including 2022 releases, via Callaway. 

One: A classically shaped heel toe weighted putter with a crank neck hosel creating moderate toe hang making it suitable for strokes that have moderate arc and face rotation

Two: A classically shaped heel toe weighted putter with a crank neck hosel creating moderate toe hang making it suitable for strokes that have moderate arc and face rotation. Less rounded than the One.

Three: A classically shaped heel toe weighted putter with a flow neck hosel yielding more toe hang making it suitable for strokes with more aggressive swing arc and face rotation

Double Wide (CH, CB): CH: A wide blade with a crank neck hosel yielding moderate toe hang making it suitable for strokes with moderate swing arc and face rotation. CS: Face-balanced center shafted wide blade making it suitable for strokes with minimal swing arc and face rotation

Triple Wide (DB, CS): DB: A face-balanced double bend wide blade making it suitable for strokes with minimal swing arc and face rotation. CS: A face-balanced center shafted wide blade making it suitable for strokes with minimal swing arc and face rotation.

Rossie: (DB, S): DB: A face-balanced double bend mallet suitable for strokes with minimal arc and face rotation. S: A mallet with a short slant hosel, suitable for strokes with arc and face rotation.

Seven (DB, S, CH): DB: A face-balanced double bend mallet suitable for strokes with minimal arc and face rotation. S:  mallet with a short slant hosel, suitable for strokes with arc and face rotation. CH: a mallet with a crank hosel, suitable for strokes with moderate arc and face rotation.
