ACCRA Concept CS1 Golf Driver Shaft Review

ACCRA Concept CS1 Driver Shaft

ACCRAconceptCS!_ImagePremium Golf Management evolved from a Canadian distributor of golf shafts to a producer of the ACCRA brand of golf shafts. They have long term business relationships with most of the professional golf club fitter / builders in the world. The golf fitters that attend the annual PGA merchandise show in Florida all arrive a day early for ACCRA day. A day of golf hosted by ACCRA  gives them all a chance to renew relationships and exchange ideas.
The 2014 Concept CS1 is another step in the evolution of ACCRA. Shown to the right is a shaft summary document that comes wrapped around every Concept golf shaft.

Several years ago PGMC, purchased one of the Fit2Score shaft measuring instruments. It brought manufacturing consistency into focus as it has now for the several shaft companies that own the instrument. Through a partnership with Mark Timmes a fully automatic shaft measuring instrument was invented.

    Russ, I think those weight numbers are in grams and not pounds.

    Also, I really think you and all the guys are doing an awesome job with these reviews. Keep it up!

      All of the software that accompanies the new version of the EI measuring instrument is being rewritten. You are right, grams. I checked the software just now, It is two minor revisions past what was used in this review. I already fixed that error. Thanks for finding it.
      The deflection force numbers are in lbs. It is an interesting way of looking at relative shaft stiffness across brands. I clamp a driver shaft 38.25″ from the tip. A load cell tower is 2.25″ from the tip. The shaft is deflected 1″ and the load cell is zeroed. This removes the variability shaft bow would have on a deflection measurement. Then the shaft is bent 4 more inches and the load cell number is recorded. Every shaft I measure on this site is measured exactly the same way. This method makes much more sense that looking at weight and stiffness notations on a shaft. It gives readers on this site are real comparison standard for butt stiffness of all the shafts that are reviewed.
