About Dumina
Designing and building golf shafts in Korea since 2013. Dumina is the maker behind autoFlex and Autopower.
Two names on the shafts. One place behind them.
autoFlex and Autopower sit side by side on our building. One explores a light, soft swing; the other, a substantial, firm response. Dumina began with Autopower in 2013 and introduced autoFlex in 2020.
We design and build both brands at the same factory in Korea. Golfers seek different sensations. That is why we make shafts in two distinct directions.
What defines Dumina
The technology →Dumina began with Autopower, the line that still carries the firmer, more substantial feel.
Every shaft is designed and built at our own factory. No OEM, no outsourced line — the maker and the brand are the same company.
Seven models between them, from a single-spec 39-gram driver shaft to tour-weight builds.
Shaft CPM is measured before shipping. It describes the product; fitting also considers the golfer’s swing speed and tempo.
