Product Description
Precision engineered for a higher, more forgiving flight.
The Ryoma CB300 brings the same core technology found in Ryoma's MB200 into a shape built for golfers who want consistency without needing to manipulate the clubhead through impact. Every element of the head — weighting, face structure, and sole geometry — is arranged to push the center of gravity low and deep, so the ball launches higher and stops faster with less effort from the swing.
What makes the CB300 different:
-
90g Tungsten "Monster Booster" — A dense 90-gram tungsten weight (18 specific gravity) sits low in the sole, dramatically lowering and deepening the center of gravity. The result is an easier, higher launch and a noticeably wider sweet spot.
-
Hyper Forged Cup Face with Spider Rib — A 1.4mm forged face is reinforced from behind by a 1.2mm internal rib structure. This lets the face flex more freely at impact, helping preserve ball speed on strikes toward the toe, heel, or high on the face — not just center contact.
-
0.5mm Power Spring Zone — The sole beneath the cup face thins to just 0.5mm, acting as a flexing hinge. On thin or low-face strikes, this zone helps kick the ball upward while holding onto ball speed, protecting distance even on mis-hits.
Rather than demanding a perfect strike, the CB300 is built to tighten dispersion on the shots that aren't — keeping more approaches on the green and more putts makeable.
Pre-order note: Official Japan release is scheduled for late June 2026. Orders placed now will ship on release.

Since your Shopify store is already connected here, I can go ahead and create this as a draft product in Shopify with the description, variants (head number × shaft), and specs — want me to do that, or would you rather refine the copy first?
