How many times have you heard it said that there is no standard rating system for golf shafts. When I entered the golf club fitting business over a decade ago I learned what a huge problem that for fitting golf clubs. Creating a uniform system was possible, it just had not been done. I learned what I could from golf shaft engineers, purchased the instruments that were available and invented what was not. It took a few years to refine the process and many, many years to acquire and measure the popular golf shafts. This site presents the knowledge of golf shafts that has not been shared by the shaft companies that have the data. Not all do, and many have purchased my EI instrument for their labs.

If you are new to this site, the technology menu is a collection of articles that will help you understanding golf shaft design and the attributes of the golf shaft that can be independently measured. My objective in creating this site is to balance the marketing messages of the golf business with some science. And ultimately to help you make better decisions when selecting your golf clubs.

It took years to understand shaft measurement and many more years to accumulate a meaningful database of shaft measurements. The magnitude of that accomplishment did not occur to me until a golf shaft company owner said it to me.

If you believe as I do that the golf shaft is essential to good golf, register now. Testing shafts and writing articles takes a great amount of time. The membership fee underwrites the time and resources needed to keep this site going and growing. It also funds the acquisition of shafts that have not been available. You will notice, this site is does not run ads, that allows me to remain unbiased in the articles.

If you are a golf professional and would like access to more data there are two choices. Golf Professional subscribers get access to a larger set of data and individual profiles of all the shaft model weights and stiffness variations that were made available. Fit2Score Affiliates have access to the entire database through Excel. To hear a recent podcast interview I did about golf shafts with Tony Wright, a Fit2Score Software Affiliate, Click Here.

The 2018 Aldila Synergy is the first golf shaft I know of to incorporate Graphene. What exactly does this material, that is one atom thick bring, to golf shafts. I looked it up at Wikipedia and learned that it earned its early researchers a Nobel Prize in 2010. Golf is not the first sports application, Head put in into tennis rackets in 2015. They are played by the worlds best tennis players. The racket reviews tell us that they bring new levels of stability to the racket frame.

Mitsubishi Chemical Tensei AV Blue Driver Shaft Review

Mitsubishi Chemical Tensei AV Blue Driver Shaft Review

By Russ Ryden, Fit2Score, A Dallas Fort Worth Club Fitter & Club Maker

Golf Digest Certified America’s 100 Best Club Fitter

The Tensei AV is the successor to the Tensei CK. There were two versions of the Mitsubishi Tensei golf shaft, now there are three. My understanding is that the AV series will replace the CK series. The Tensei CK, like the Tensei Pro CK has a Carbon Fiber/DuPont™ Kevlar® (CK) weave just below the grip. This material dramatically reduces hoop deformation in the critical section of the what were wall thickness is thin. The Pro CK version has three times the length of this woven material as the OEM, CK version. Measurements and hitting experience shot a dramatic shot dispersion from stabilizing this section of the shaft with the long woven section of the Pro version. The shot dispersion effect from the 4″ section in the OEM version is not as dramatic.

The Tensei AV changes this. The woven section is the same length as we see in the Tensei Pro. The woven material is different. This video was cut out of a longer interview. The second camera was out of focus, but the explanation of the AV technology was to good to ignore.

Nippon 123 Driver Fitting System Review

Nippon 123 Driver Fitting System Review

By Russ Ryden, Fit2Score, A Dallas Fort Worth Club Fitter & Club Maker

Golf Digest Certified America’s 100 Best Club Fitter

Most reviews here are focused on a single shaft model. The Nippon 123 system is three shafts brought to market as a fitting system. There are three profiles, each with an array of stiffness and weight. This is a fitting system that will soon be accompanied by documentation to guide the fitter using it. Mark Pekarek has been fitting over 35 years. Much of that time his company, Shaftology has been the distributor for Nippon shafts in the US. When I started with Nippon, Shaftology was the only source for Nippon shafts in America. Their distributors were regionally placed and had to demonstrate their golf competence as representative of the Nippon brand. Before you look at the data I recommend you watch this video shot at the 2019 PGA Merchandise show where the system was announced to the golf business.

This is the first time, to my knowledge, that a set of shafts has been designed and presented as a fitting system. Those of us with ample fitting experience have put together our own mix of fitting shafts. It takes years of experience and access to a comprehensive database of shaft properties to outfit a fitting cart for systematic fitting. As Mark said, the profiles in this system are different enough to make a difference to the average golfer.

Aldila XTorsion Golf Shaft Review

Aldila XTorsion Copper & XTorsion Green  Shaft Review

By Russ Ryden, Fit2Score, A Dallas Fort Worth Club Fitter & Club Maker

The Aldila Xtorsion driver shaft have a clearly visible woven material in the lower half of the shafts. Aldila calls the material, MAMBA, Multi-Axial Material Bias Angle technology. It is woven at a 45 degree angle which provides torsional stability to the lower half of the shaft where it is most important. This can be seen in the GJ or torsional profile of the shafts. The GJ profile tips downward from the mid section to the tip. I also see high and stable hoop strength resulting from the woven material. This is similar to the woven section of the Mitsubishi Tensei Pro shafts that is located just below the grip. When I look at the Xtorsion Copper EI profile I am reminded of the very popular EI profile of the Nippon Modus 120’s.

Mitsubishi Tensei Pro Red Golf Shaft Review

Mitsubishi Tensei Pro Red Golf Shaft Review

By Russ Ryden, Fit2Score, A Dallas Fort Worth Club Fitter & Club Maker
Highlands Performance Golf Center, Carrollton Texas

The last profile added to the Mitsubishi Chemical Tensei Pro family of driver shafts is the Tensei Pro Red. Like the other Tensei Pro driver shafts I has a carbon Fiber Kevlar woven material place just below the hands. As you can see in the chart, this material substantially  increases hoop strength in this area of the shaft. Hoop deformation in carbon fiber golf shafts is a function of wall thickness. The wall thickness in the butt end of a golf shaft is thin. Therefore the shaft deforms more. This has classical be called ovaling. Ovaling is thought to create dispersion. I have seen various materials use in this area to stabilize driver shafts. I have never seen as dramatic an effect on hoop deformation as I see in the Tensei Pro. Take note, the OEM shafts have only 4″ of this material which is little more than cosmetics. The Tensei Pro models have 11+” and the hoop deformation profiles are dramatically lower in this area.
