J-Spec Proto

ACCRA introduces the our first shaft designed specifically for the player who desires a high performance shaft using the highest modulus materials from Torey Japan and Boron in the tip section that will deliver maximum stability at “normal” clubhead speeds.
Discerning golfers who want to play golf at a high level but have seen swing speeds diminish due to age or injuries require a shaft that provides the stability of “Tour” shafts at a lighter weight. The J-Spec N-Series offers this.

ACCRA J-Spec Golf Shafts

As per Japanese standards, the N Series is based on 3 swing speed ranges using “Meters Per Second” and color coded for convenience.
S flex – N3842 (Blue)
R flex – N3640 (Red)
A/L Flex – N3438 (Orange)

A golfer can expect…..
~ Mid/high launch conditions
~ Mid spin rates
~ An EI curve that promotes maximum energy transfer.
~ Superior transition and timing during the swing.

Design Features….
~ High elasticity carbon graphite materials over the entire length of the shaft for speed and power.
~ 4 axis weave in the butt section for stability and to promote timing during the transition.
~ Boron graphite combination in the tip section for a strong impact position even during off center hits.
~ Super high modulus materials to offer the best possible “feel” on impact.

This is the first truly innovative and high tech shaft designed for those who want “the best” at traditional clubhead speeds.
