Shaft Flex: What’s Right For Your Swing

Shaft flex can have a significant effect with your ball striking, we all know this, but shaft flex can also have an effect on what type of swing you have.

There’s more to consider than, what is the right shaft flex for your swing profile? You should also take into consideration, what is the right shaft flex for your acceleration profile.

If you have an early release or cast the club, even if you have a faster swing speed, you can most likely get away with a softer flex shaft. If you create and hold significant lag, even with a slower swing speed, you can most likely fit yourself with a stiffer flex shaft.

Taking these points into consideration your shaft flex will be critical in helping maximize your consistency.

    What about swing speed? My swing speed is down to 75 mph, is it time for senior flex?

      More likely time to start croquet. Jut kidding! Senior flex is the answer.

      Yes if you are down to 75 mph you will want to look at the Senior flex or the Lite flex shafts. Both have generally more flex and an overall lighter weight profile that allows for the ball flight trajectory that you need for your swing speed.

      Thanks for this – I’ve always had questions about shaft flex. Is it possible to name the varieties of shafts – and what swing speeds they relate to? For example, between X and X mph use and S-flex shaft, etc.? Thanks.

        Rick,
        Good question. There are no industry standards so these are general suggestions but here are the ranges:
        105+ mph=X Flex
        95-104 mph=S Flex
        85-94 mph= R Flex
        75-84 mph=A Flex
        74 below mph=L Flex
        There are differences within a flex category as well based upon where the kick point is located but the range above is a good starting point to determine what flex is right for you.

    Light and stiff is the desired profile. The stiffest shaft that you can swing at your best swing speed without inducing inertial deformation. That is all. Flex is bad, lag is bad. Deliver the club face back to address position, at speed.

      Will,
      Good comments that I agree with. The one added aspect is acceleration. Players with smooth acceleration profiles generally can swing shafts that are more flexible then players with high acceleration profiles at the same speed.

    I’m 85 years of age, play off 32 hdcp, and three times a week
    What flex staff would you recommend?

    • Gene Parente October 12, 2018 at 5:52 pm #

      Neil,

      I would recommend looking at a “senior” flex or a “Lite” flex shaft.

    I hit my driver about 170 yards, my 5 iron 100 to 110, Irons are steel regular flex, in a points game I am a 16, my usga handicap is 20.. The question is a new set of clubs steel or graphite and what flex. I’m 80 years old. Larrymassillon@aol.com

      Larry,
      I would recommend a senior flex or a Lite flex driver. I also would recommend a slightly longer club at 45.5 inches as this will give you a bit more distance.
      Finally make sure that your loft is 12 degrees. This will help you get the trajectory you need to maximize distance.
