Description

ACCRA iSeries iSi Iron Shafts

 

ACCRA iSeries iSi Iron Shafts bring precision graphite performance to golfers seeking customized control and elite-level feel. Designed with high modulus composite materials, the iSi model enhances energy transfer while maintaining the smooth, connected feel that serious players demand. From elite amateurs to weekend grinders, ACCRA iSeries iSi Iron Shafts are engineered to match your game — exactly where it is, and where it's headed.

 

At the heart of the design is a proprietary constant taper geometry, built to eliminate weak zones and maintain shaft integrity from grip to tip. This stability results in tighter dispersion and repeatable flight across the bag. The tip section is specifically engineered for flight customization — enabling fitters to “mix and match” weight and launch profiles across the set. Whether you’re crafting a progressive flighted set or dialing in a one-length build, ACCRA iSeries iSi Iron Shafts offer flexibility without compromise.

 

Available in 40g, 50g, 60g, 70g, and 80g weight classes, each shaft can be tuned to five distinct flex levels. That means fitters can refine trajectory, spin, and feel far beyond the limits of standard graphite offerings. From high-launching short irons to low-spin long irons, iSeries iSi provides the framework for total iron performance — personalized at every level.
