0.5mm offset
A neutral face through impact in every iron.
Build Options
A tour blade with 0.5mm offset and toe tungsten to kill the left miss
Sub 70 Golf · IronsThe Sub 70 649 MB Tour Forged Irons evolve the 639 MB for elite players. The sole is 1mm wider to resist digging for high swing speeds and steep attack angles, the mass distribution is reworked for slightly higher launch, and offset is just 0.5mm throughout the set. A rear port removes 6 grams that are moved to a tungsten toe weight, keeping the face stable through impact and reducing the left miss.

Why golfers choose it
A neutral face through impact in every iron.
6g of tungsten in the toe stabilizes the face.
Resists digging for fast, steep swings.
