The Diamana line of golf shafts from Mitsubishi Chemical is one of the most well-established names in high performance driver and fairway wood graphite shafts. Currently being used by many of the top name players in the world, Tiger Woods, Justin Rose, and Justin Thomas to name a few, the Diamana has seen worldwide success in several iterations and continues to improve the performance of elite and casual golfers. The newest line of Diamana shafts features the typical whiteboard style – DF, the blueboard style – BF, and an all new hybrid style – ZF. This review will take a deep dive into the brand new ZF that can be found in Justin Thomas driver currently.

Key Features

The Diamana ZF shaft features technologies such as MR70 carbon fiber, Boron fibers, a special ion plating the to create stability, stiffness, and sophistication.

The ZF shaft is specifically engineered to fall between the bend profiles of the DF and BF to create a consistent golf shaft with mid to low launch and low spin.

The ZF boasts a stable butt and tip section with a slightly softer mid-section for optimized feel and energy transfer at a variety of swing speeds.

Design and Technology

Mitsubishi designed the ZF shaft to be incredibly stable but create feel and feedback that lets golfers effortlessly produce more acceleration through the hitting area. MR70 carbon fiber has been integrated into the ZF shaft specifically to create more strength, (20% stronger than other materials) and more consistency (10% higher modulus). Boron is used to reinforce the golf shaft to stand up to all types of swing style and speeds and create enhanced energy transfer for better results at impact.

The ZF series is designed to have a moderately stronger and more stable butt and tip section, with a slightly softer and more active middle section. This produces a shaft that is incredibly solid during the swing loading and unloading, as well as at impact, but with smoother energy transfer and easier acceleration throughout the swing.

The ZF series is part of Mitsubishi's Fourth Generation Diamana shaft lineup, which utilizes two key technologies:

  1. MR70 carbon fiber material - This proprietary carbon fiber provides carefully calibrated stiffness and stability to the shaft.
  2. Boron fiber - The inclusion of boron fiber also contributes to the shaft's stability and performance characteristics.

Additionally, the ZF series offers the first-ever 40g Fourth Generation Diamana shaft option, providing golfers with a lighter-weight shaft optionOverall, the Mitsubishi Diamana ZF shaft is designed to deliver increased clubhead acceleration while maintaining stability and control through impact, making it suitable for a wide range of players.


  • The Material Difference of Mitsubishi can be felt and seen with the extreme stability and enhanced feel of the Diamana ZF shaft.
  • MR70 and Boron combine to create a golf shaft that produces more effortless power at impact from increased swing speed acceleration.
  • The versatility of the ZF shaft shines a wide variety of driver and fairway wood models and can be tailored to almost any swing style.


  • The ZF shaft is versatile and players looking for the ultimate in low or high launch will likely be better fit into a narrower category of golf shaft.
  • Finding a store or club fitting location to get fit or to demo the Diamana ZF shaft may be challenging in many areas of the world.
  • The improvements of this generation Diamana shaft over previous models may not fully warrant a switch if players have been well fit.

Our Experience

Diamana is a brand I have used and loved many times. My one exception with it has always been, the whiteboard style gives me the best numbers, but the blueboard feels so much better. Also, the difference in these two, now DF and BF, models made it difficult to fit golfers of select swing speeds or that required more versatility when coming from different areas of the golf course with a fairway wood. ZF solves each of these problems wonderfully. ZF is versatile enough to give to players that swing at almost any speed and can be used in a fairway wood to launch the golf ball higher into greens from fairways and roughs or create laser-like penetrating shots with that same club coming from the tee.

It is extremely easy to see why Justin Thomas and others have moved to the ZF shaft. Its stability helped me tighten my strike dispersion and enabled me to hit any shot I wanted to during testing and play. I have played Mitsubishi’s Tensei CK Pro Orange shaft for more than two season now but the ZF is making a serious contention for my driver spot and my fairway wood as well. The standout feature of the Diamana ZF shaft is how easily I could hit it high, hit it low, and the versatility it created from a variety of lies with my fairway woods.

Frequently Asked Questions
