ACCRA has been a leader on PGA Tours around the globe, with multiple wins every season since its introduction on PGA, European PGA, Champions, Nationwide, and LPGA tours. More than 60 wins can be attributed to players using ACCRA shafts on the PGA and Euro PGA Tours since our inception. ACCRA shafts are played and have multiple victories on the LPGA, Champions, NCAA, and at club championships all over the world. But what we are most proud of is the number of $2 Nassaus that have been contested by discerning golfers around the world using ACCRA shafts.
ACCRA’s dedication to Professional Club Fitters is unparalleled. Working exclusively with more than 400 of the world’s best club fitters and club builders, ACCRA accesses this unique knowledge base when designing new products.
The S3 (Shaft simulation System) shaft measuring device enables the engineers at ACCRA to completely profile any golf shaft in a matter of a couple of minutes. The S3 system provides us with an immediate blue print of every shaft, enabling ACCRA to provide the best QC (Quality Control) in the industry and the best system for developing new shafts for the future.
This project was developed in conjunction with Mark Timms and Cool Clubs, with the ultimate goal being to develop the most advanced shaft profiling machine in the industry….we have succeeded!
Simon Grondin was/is the developer of this device, please look for more information on the S3 and Mr. Grondin on recent video’s by ACCRA and Cool Clubs.
The S3 machine provides a multitude of information in just minutes……
- Straightness – using a high resolution imaging system while rotating the shaft, the machine provides instant and precise feedback of a shafts straightness profile.
- By duplicating how a shaft is loaded during a golf swing, the machine’s imaging system can quickly measure the shafts profile.
- E.I. curve – Using the thousands of data points from a shaft’s bend profile, the machine instantly calculates a continuous E.I. curve. System provides a curve on multiple planes by rotating the shaft.
- Deflection – System provides a dynamic representation of the deflection profile on multiple planes.
- Frequency – S3 give frequency data on multiple planes, providing averages and discrepancies.
- S3 Consistency factor – An overall rating of the quality of the shaft taking into account consistencies such as…straightness, wall thickness, materials and interior/exterior diameter consistencies.
- Torque – using precision motors, the machine completes each test with a torque measurement.
The machine is also able to determine if a shaft meets all of ACCRA’s high quality control standards in real time during analysis.
These measurements are all done through an automated system that combines robotics and data acquisition technologies to eliminating the human error normally associated with multiple measurements. This system literally takes the place of a series of measurements on multiple devices that may take up to an hour to gather……in just a couple of minutes. The key to this system is the ability to provide data on multiple planes and then differentiating this data to provide an overall measurement of shaft consistency.
This may just be the most significant golf club fitting technology in the past 10 years! ACCRA realized that the world’s best golfers continue to use different shaft profiles throughout their set makeups. This is due to a significant flaw in the design of most golf shafts. Shaft manufacturers make shafts stiffer in the tip as they add weight. This, combined with the theory that shafts should be tipped for fairway woods, means that Tour Players must look for more responsive tip shafts for those clubs.
ACCRA dynamically designs shafts to offer identical feel in driver, fairway woods, and hybrids using a proprietary technology called “DyMatch”. If you use a “DyMatched” set of woods custom fit by a certified ACCRA fitter, rest assured that you will receive similar flight characteristics, feel, and performance throughout your set.
ACCRA golf shafts, within a similar model, all share the same frequency flex. This means that a professional fitter can determine a golfer’s flex and then comfortably test different weight shafts, knowing that they are all the same flex by frequency. Virtually all other shaft manufacturers’ shafts get stiffer as they get heavier. This is a technology pioneered by ACCRA and is included in all models of ACCRA shafts.
ACCRA uses high modulus, low resin prepreg composite materials to minimize the wall thickness to enhance feedback, energy transfer, and most importantly the smooth ACCRA feel. Advancements in composite materials has enabled ACCRA to develop more efficient shafts than ever before using a higher graphite content in each layer of material. This technology also reduces inconsistencies within the shaft resulting faster “recovery” to increase clubhead speed and ball speed.
ACCRA incorporates several different weave technologies into different models of shafts. Combining different modulus of composite materials in a single sheet of prepreg enables engineers to manipulate flexural rigidity and torsional strength of specific sections of a shaft
ACCRA believes that a constant or uniform taper from the butt section of the shaft through the tip section provides the maximum energy transfer and best “feel” for the golfer. ACCRA incorporates this technology in virtually every shaft in the line.
