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.


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.

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).  ——————————————————————————————–
