The designs of all Xcaliber shafts are based on our two-fold mission statement:
- To tell the golfing community the truth about golf shaft design as it relates to performance and cost.
- To provide golfers of all abilities – from a Tour pro to a casual weekend golfer – the highest performing, best quality, and most innovative golf shafts at fair prices.
High Performing Golf Shafts
Innovative Golf Shafts at Fair Prices
With over 300 Tour wins to date, that mission statement is Xcaliber’s reality.Read More
Designing the #1 Shaft in Golf
I’ve been in the golf industry since 1991. That was the year that two partners and I took over a small, struggling shaft company in El Cajon, California, called Grafalloy. At the time, Grafalloy had annual sales around $250,000, a limited product line, no real technical expertise, and zero marketing capabilities. Less than 8 years later, we had the #1 shaft on Tour and annual sales of $20 million.
My initial responsibilities and corporate goals were to give Grafalloy solid manufacturing and research and development foundations. To do this, I tapped into my years in the aerospace program designing and manufacturing detail composite structures for the Space Shuttle and a host of other General Dynamic programs.
The goal was to innovate Grafalloy’s design approach and manufacturing processes – not just to compete with any shaft company in the world – but to produce the most consistent and highest performing shafts in the world.
My personal goals and commitments were much higher – I aimed to design, manufacture and verify through scientific testing protocols the consistency and performance of a super lightweight shaft series that every PGA Tour player could and would put into play. No one else had ever accomplished that before – there was no such shaft.
After 3+ years, that shaft became known as the ProLite. It quickly became the #1 shaft on the PGA and Senior PGA Tours, and to this day the ProLite has earned more Tour wins than any shaft in the history of golf.
The Importance of Science in Shaft Design
In any new competitive environment, one must first evaluate the competition. When developing the Xcaliber products, it didn’t take long to realize that most, if not all marketing in golf, especially for golf shafts, was not based not on empirical data. Rather, it relied on whatever story each company’s sales and marketing departments could spin. Claims of specific shaft properties – torque, stiffness, weight, and balance point (a critical but often overlooked design feature) – were still being measured using oversimplified testing techniques which quite honestly had zero bearing on shaft performance. Claims of shaft-to-shaft consistency were also completely overstated.
The most important feature of any composite structure, from those used on a Space Shuttle or in a carbon fiber/epoxy golf shaft, is its design. Everything relies on design – performance, manufacturing, quality, cost and consistency.
There are two critical features in shaft design:
- Distribution of all physical properties – strength/stiffness, weight, torsional resistance, etc.
- Balance – the balance of the carbon fibers’ strengths, densities, and binding agents around the entire 360 degrees of a shaft.
The distribution of mechanical properties is the heart and soul of any golf shaft design and is directly related to performance – not any single specification as shaft companies have been proposing forever. Having a thorough understanding of and experience in designing to this all-encompassing criteria is simply essential to creating consistent, quality golf shafts for all types of players and individual swing profiles.
Balancing all the materials of construction 360 degrees around the tooling used to produce a shaft is the second essential criteria of design – the body of a golf shaft. All commercial (low cost) and even some premium (high cost) shafts truthfully are not designed this way because of cost concerns. Balance is achieved through design, and as importantly, through strict manufacturing processes and material control procedures.
The Xcaliber Difference
All Xcaliber shafts are meticulously designed and performance-optimized using a wide-spectrum player test protocol with golfers of all abilities recording and comparing objective (distance, launch, spin, etc.) and subjective (feel) data to the highest standards.
The manufacturing process is only approved for production after a lengthy beta process evaluation, which sets very strict quality controls at every fabrication step, all of which are verified at the end of fabrication and before cosmetic applications.
Unlike more than 80% of all high-volume shaft manufacturing around the world, Xcaliber products are fabricated slowly, and without regard to costs. With this dedication to detail, the shaft-to-shaft, consistent performance of all Xcaliber shafts is assured.
I’ve put my name on this company – Arthur Xtreme Engineering, LLC – and on all Xcaliber products. That’s an important aspect to remember. I owe it to myself personally and to golfers everywhere to take extraordinary measures and time to give you the best products possible, at fair and reasonable prices.
And that’s my truth.
