AUTOFLEX GOLF SHAFTS
We finally found it ! Finally, we can introduce the shaft of your dreams.
autoFlex shaft with K.H.T (Korea Hidden Technology) applied is a new concept of the shaft that changed the common sense of the ordinary shaft.
This soft autoFlex Shaft will provide you the fun that you have never experienced.
The Autoflex shaft was not intended to be only used as a long drive shaft. Rather, Dumina Co. intended the shaft to help make the game of golf easier by helping slow and average swing speed golfers swing faster without swinging harder. Having said that, the Autoflex shaft line up can cover from 65mph to 150+mph swing speeds.
Performance
LIGHTER – Up to 20-30g lighter than conventional driver shafts to increase speed and decrease body strain.
CONSISTENCY – The shaft automatically optimizes the transfer of energy despite different swing speeds.
INCREASED DISTANCE – Increases head speed while providing stable swing posture for better distance and accuracy.
This soft autoFlex Shaft will provide you the fun that you have never experienced.
- Up to 20~30 gram lighter than the conventional shafts.
- Select the weight of autoFlex shaft according to the swing speeds.
- The shaft automatically optimize the transfer of energy despite different swing speeds.

Structural Design
The unique characteristics of Autoflex shafts make it lighter than conventional shafts with a much lower CPM. Due to the more flexible nature, a higher swing weight may cause the club head to wobble on the downswing transition. This may result in off-center impact for loss of distance and accuracy. A swing weight of D1 is found to be good for many golfers, but some have seen excellent results at D0 and even up to D3~D4 (for sf505x and xx shafts).
The raw uncut length is 45 inches, so when fitted to a driver head comes to about 46.5~47 inches. There is no ideal length and the butt end can be trimmed to make any total driver length depending on individual golfer preference (between 44~47 inches).
