Bridge design
Sits between the CB and MB for flexible combo sets.
Build Options
A forged tour cavity that bridges the 659 CB and MB
Sub 70 Golf · IronsThe Sub 70 659 TC Forged Irons fill the gap between the 659 CB and MB, making them ideal for combo sets or as a complete set on their own. Forged and milled from a single billet of DT-4 steel, they give a soft, informative feel. The sole design and weighting provide some forgiveness, and a 6-gram toe weight in the 7-iron through AW keeps the face stable and helps prevent it from closing.
