ST-Z 230 Tech

Balanced Composite for neutral weight distribution

ST-Z 230 Tech

Design focus is a combination of deeper CG and shorter CG distance for a balance of workability in both directions while providing higher MOI and mid/low spin.

“Tour tests for the ST 230 SERIES have all been very consistent – relief that the look is similar at address. Then shock at how much better the new ST-Z 230 feels off the face. Ball speeds are up on average 2-5mph with a drop in back spin of around 200 rpm.”
