Used Callaway Quantum Single Irons

2026

Quantum's argument sits in the face: titanium, poly mesh and carbon fibre layered into one structure rather than a titanium face with carbon elsewhere. Callaway calls it Tri-Force, and pairs it with Speed Wave 2.0, which pushes mass low and forward to hold ball speed on strikes low on the face.
