UST Mamiya Competition 65 Series Iron Shaft - R/S flex
The UST Mamiya Competition 65 Series Iron Shaft is a premium graphite shaft engineered for club builders and golfers who demand outstanding fitting flexibility without compromising on performance. Offered in a Regular/Stiff (R/S) combination flex profile with a mid kick point, it delivers the ideal balance of distance and control for a broad range of swing speeds. Finished in a striking red and black colour scheme, this shaft is a trusted, value-driven upgrade for iron builds at every level.
- R/S Combination Flex: A single shaft covers both Regular and Stiff flex needs, making it the ultimate choice for custom club builders fitting multiple player profiles.
- Mid Kick Point: The R/S flex is designated a mid kick point, promoting a penetrating, controlled ball flight that suits a wide range of iron players.
- Lightweight 65g Design: At approximately 65 grams, the shaft reduces overall club weight to help maximise swing speed and distance through the set.
- .370" Parallel Tip Diameter: The standard .370" tip fits the vast majority of iron heads on the market, with longer parallel sections for versatile trimming to length and flex.
- Mid-Range Torque: Balanced torque characteristics deliver responsive feel and consistent energy transfer through impact across all irons in the set.
- Stylish Red & Black Finish: Eye-catching graphics give your iron build a professional, premium appearance straight out of the factory.
- Exceptional Value: A game-enhancing graphite upgrade at an accessible price point, delivering performance benefits typically associated with far more expensive shafts.
Combination Flex Technology
The Competition 65 Series uses longer parallel tip sections combined with a R/S combination flex profile. This means a single shaft can be tip-trimmed to dial in either a Regular or a Stiff flex, giving club builders the freedom to fit a wider range of players from a single inventory SKU — saving time and cost without sacrificing precision.
Mid Kick Point & Distance
The R/S flex variant of the Competition 65 is engineered with a mid kick point, which promotes a mid-trajectory ball flight ideal for the broadest category of iron players. Combined with the lightweight 65g construction, the shaft encourages faster club head speeds and greater distance throughout the iron set, without sacrificing stability at impact.
