The ONE Length counterpart of the SPEEDZONE irons are designed to 7-iron length (37.50") all through the set. This helps to promote one repeatable setup and swing between clubs for more consistency and accuracy. The SpeedZone irons with their Carbon Fiber Topline gives the iron an ultra low CG and helps to create maximum speed and launch.
The forged face insert features a 35% larger Sweet Zone area, and a 8% deeper undercut that enhances your ball speed and launch across the face.
Extreme heel and toe weighting creates a lower CG and a higher MOI than most traditional iron shapes allow. This grants you the stability needed even if the hit is off center.
A clever and lightweight medallion works to damp vibrations giving you excellent sound and feel.
