ACCRA introduces revolutionary golf shaft design – ACCRA DYMATCH
PGMC Kingston Ontario – Premium golf shaft manufacturer ACCRA is poised to introduce an entire line of new golf shafts using a revolutionary method of concept and design.
On the heals of 6 months of unprecedented growth, including it’s best month in it’s 5 year history (February 2009), ACCRA is set to begin shipping ACCRA DYMATCH mid March 2009.
Why?
Tour reps and club fitters would “dial in” a player to a driver shaft/head combo……. then had to start all over with the fairway wood and hybrid!
We began analyzing what shafts players were using in their drivers, fairway woods and hybrids and we noticed that the majority of players were using stiffer tip/lower torque shafts in their drivers than in their fairway woods! Now, Tour players, but they “feel” everything and know what works!
So then we took a look at the method that shaft companies uses to create driver an fairway wood shafts…..
We design cool 55, 65, 75 gram shafts using specific profiles, but as we go from 65 to 75 grams (using the same profile) the tip tends to get stiffer and the torque usually gets lower!
Now consider the size and shape of the heads …..driver, fairway woods, and hybrids.
You will notice that the Center of Gravity (CG) moves closer to the point where the shaft enters the club as we move from driver to fairway wood, to hybrid.
Therefore we really don’t require a stiffer tip or lower torque to maintain stability in the smaller heads (fairway woods and hybrids).
Shaft companies tend to make the heavier (fairway wood) shafts with firmer tip sections and usually lower torque….. And then tell club fitters and Tour vans to “tip it” up to 2 inches!!!!! This makes little sense, forcing Tour players and custom club fitters to find a softer tipped shaft for their fairway woods, usually from a different company!!!!
ACCRA DYMATCH…… Is just common sense!!!!” Stated Mr. Robertson.
“So we challenged our engineers to design a great driver shaft in 55 grams, 65 grams and 75 grams (all with slightly more stable tip sections than we had done before and butt sections that were easier to “load” than any previous ACCRA), once we test these driver shafts with Tour players and average golfers and know they work……then we measured them dynamically! not statically!
This entailed assembling the shafts into a finished product.
So we took the assembled clubs and then put them through Robot, Canon, strain gauge, and human tests to determined the amount of torque and tip deflection a head receives on center hits at different impact speeds and positions.
Then we challenged our engineers to
design a fairway wood shaft and hybrid shaft to “MATCH” these numbers in “DYNAMIC” form (at length, with a head, grip, and being swung). Honestly who cares if a fairway wood is the same profile as your driver and is 10 grams heavier….. but doesn’t “feel” anything like it! Heck that’s what’s happening on Tour….. players will try the 10 gram heavier version of their driver shaft and inevitably it doesn’t work!!
So why not actually design a fairway wood shaft and hybrid shaft that will react identically to a driver shaft when hit in assembled form. this is where we came in!
So 8 revisions and dozens of trials have culminated in the first completely “DYNAMICALLY MATCHED” shaft system ever created!
Series #1 – 55 gram driver shaft, 65 gram fairway wood shaft, 75 gram hybrid.
Series #2 – 65 gram driver shaft, 75 gram fairway wood shaft, 85 gram hybrid.
Series #3 – 75 gram driver shaft, 85 gram fairway wood shaft, 95 gram hybrid.
Bonus 45 gram driver shaft and 98 gram “Tour” shaft.” Continued Mr. Robertson.
During the design and production process, testing of “traditional” driver, fairway wood combinations consistently showed dramatic variances in head twisting and shaft deflection between the driver and fairway woods.
With ACCRA DYMATCH, the reaction of the head through the force of impact remain constant!
