Used Callaway Quantum

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.

FAQs

The questions buyers ask most about these clubs.

What separates the six Quantum trims?

Max is the neutral, full-size head sold across the widest club range; Max D adds heel-side weight for a draw; Max Fast is the lightest build for players who need more speed; Max OS is the largest head, an iron-and-hybrid proposition rather than a wood one; and the two Triple Diamond heads are the compact, shot-shaper's builds.

Is Triple Diamond available beyond the driver?

Only as a 3 wood — Triple Diamond Max stays a driver alone, and neither reaches the irons or hybrids, so a player who wants that shape through the bag won't find it here.

What does the Tri-Force face actually change?

It's a titanium, poly mesh and carbon fibre face shared across every Quantum head, paired with Speed Wave 2.0 to hold ball speed on strikes low on the face — the trims differ in shape and weighting, not in what the face is made of.
