Golf Shaft Reviews is my freelance journal about golf shafts. If you want to understand golf shafts you have come to the right place. Here you can learn why some shafts work for you and others do not. I encourage you share your comments about what you experience with the shafts reviewed. Learn which profiles work for you and which do not. There is a great deal to understand beyond weight and stiffness.

When I entered the golf club fitting business about 15 years ago, there was no source of information for golf shafts. There was no standard rating system for golf shaft stiffness. That was and still is a problem for fitting golf clubs. Golf shaft stiffness is not a simple concept. So as the saying goes, “Necessity is the mother of invention.” Shaft engineers and designers define golf shaft stiffness as a profile, the shape of stiffness down the length of the shaft. I have been writing about EI profiles on this journal for 7+ years. At last, the term EI profile, is part of the discussion shaft companies are having with golfers.

Creating a uniform system to profile golf shafts was possible, in fact several shaft companies had. But the infromation was not shared with golfers or golf professionals. I learned what I could from golf shaft engineers, purchased the instruments that were available and then invented my own EI instrument. It took a few years to refine the EI Instrument and many, many years to acquire and measure the popular golf shafts. This journal provides you with uniform measurements of thousands of golf shafts.

If you are new to my journal, 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 journal is to balance the marketing messages of the golf business with some science. And ultimately, help you make better decisions when selecting your golf clubs.

This journal is entirely supported by reader subscriptions. If you believe as I do, that the golf shaft is essential to good golf, please subscribe. Testing shafts and writing articles takes a great amount of time. Your subscription underwrites the time and resources needed to keep my journal going and growing. You will notice, this site is does not run ads, that allows me to remain unbiased in the articles.

This video is a detailed discussion about golf shafts stiffness and the history of how it was measured and marketed.

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. Several golf shaft companies now use the EI measuring instrument I designed and manufactured. This video is a discussion with three other Top 100 fitters about how having a shaft database changed their business.

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.

ACCRA iSeries Steel Iron Shaft Review

ACCRA iSERIES Steel Iron Shaft Review

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

Golf Digest Certified America’s 100 Best Club Fitter

the ACCRA iSeries Steel shaft is the first and only steel shaft offered by ACCRA as part of their i series line of shafts. All other iSeries shafts are carbon fiber. The ACCRA iSeries has a unique step pattern. It is stepped in the butt end and stepless from the mid section down. It also has a unique finish called Eco-Satin. It has the look of brushed chrome, but is in fact a coating that prevents rust and eliminates the chemicals required in the Nickel-Chrome plating process.

ACCRA primarily sells shaft to custom fitters. They are the house brand of Premium Golf Management out of Kingston Ontario. Premium golf Management and True Temper Sports partnered in 2016. That partnership made PGMC the distributor of True Temper, ACCRA and most recently Aerotech golf shafts to the professional golf club fitting and building community.

The ACCRA iSeries Steel iron shaft is a taper tip constant weight design available in 105, 115 and 125 gram models. There are 10 shafts in each weight enabling club fitters to adjust the set of the set by selecting the shafts needed for the set from this matrix.

Tensei Pro White 1K Golf Shaft Review

Mitsubishi Tensei Pro White 1K Driver Shaft Review

The woven Kevlar® material use by Mitsubishi Tensei Pro driver shafts have been available since 2016. They feature a Carbon Fiber/DuPont™ Kevlar® (CK) weave in the butt-section of the shaft. I have seen many shafts over the years with a woven material placed in the butt of shafts. This is as an indication that shaft manufactures recognize the thin walls near the but of the shaft deform and oval under load. The ovaling of the shaft in this area can contribute to shot dispersion. The woven Kevlar® material use by Mitsubishi is the only material I have measured to date where I can see a measurable effect. Hoop deformation significantly dips in this section of the shaft. Reduced hoop deformation in the 1K weave is the same as the CK weave. Mitsubishi tells us the 1K material transmits more feel.

Hoop deformation has a significant effect on the EI profile of the golf shaft.  Hoop deformation is manifested in the thin wall, butt section of the shaft. Mitsubishi engineering integrated the woven material hoop rigidity into the Tensei Pro designs, preserving the archetypical White, Blue and Red Board profiles of the Diamana family.

The 2021 Aldila Ascent is a reminder that Mitsubishi Chemical purchased Aldila several years ago. The design is reminiscent of several very successful Mitsubishi models in the past. Albeit with the latest prepreg and fibers.

LAGolf TRONO Shaft Review

LAGolf TRONO Driver Shaft Review

LAGolf Shafts is taking a new approach to the golf shaft business. Professional Golf playing partners participate in the design of their golf shafts. The LAGolf TRONO shaft is the first such shaft designed by Bryson DeChambeau and the LAGolf engineering team. it is unique as is Bryson DeChambeau. LAGolf is committed to being a different shaft company. The shafts will be designed in with playing partners and made in the USA. Many shafts today are made in offshore “foundries” that produce shafts for many brands. That probably accounts for much of the similarity I see in shafts across brands. Very few shafts are made in the USA. The shaft matching page of my software did not find a single match for the LAGolf Shafts TRONO.

The Trono is produced on a 16 sided mandrel. That is what the 16 on the label of the shaft indicates. Some might remember the unique Matrix HD shafts. Let’s look at this very unique golf shaft.

Most Shaft companies send in review samples. Korea Hidden Technology never replied to the request for review samples. A great many golf fitters have professional subscriptions to my software and were interested in seeing the profile of the autoFlex shafts. One of them provided a shaft to be added to the database. The profile is no longer hidden.
