Concept Series Shafts
The Concept Series 400 is a super premium shaft designed to increase stability without
sacrificing “feel”. Utilizing the most high modulus composite materials to offer torsional strength and strongest tip stability of any ACCRA shaft yet high elasticity to increase speed.
This shaft is a favorite among Tour players that prefer a smooth feeling shaft that decreases dispersion. A 360 degrees ultra light weave that runs the entire length of the shaft ensures the ultimate in performance.
A Tip EI in the 30’s, utilizing the proprietary S3 shaft profiling machine, combined with torque in the mid to low threes ensures the stoutness that stronger golfers require, and incorporating ACCRA’s “Constant flex Technology” even the lighter weight versions maintain this firmness.
Available in 55 grams through 75 grams and m3, M4, and M5, this Concept Series line of shafts gives a professional Club Fitter a great opportunity to find a great match for your swing.
If you require a lower launching shaft that promotes low spin the Concept Series 400 may be the perfect shaft for you. Please visit an ACCRA Certified Fitter to test one today.
