HYPERSONIC SPEED AND DISTANCE

The SK Fiber Hypersonic is an ultra-lightweight shaft to enable the golfer to maximize clubhead speed and distance. Versatile mid-high launching design to fit a wide array of players. The SK Fiber Hypersonic wood shafts are a counterbalanced design. The advantages of counterbalancing are that it allows you to use a slightly heavier head at normal lengths or you can increase the length slightly with standard head weights and yet maintain a normal swingweight. In both cases, this can help increase distance.

Product Questions

Are the SK Fiber Hypersonic iron shafts counterbalanced as well?
Question by: Kenny Ray on Mar 16, 2021, 10:37 AM
Not to the extent of the wood shafts. Iron heads usually do not come with weight ports for added weight or consumers don't want extended lengths over and beyond what is customary in a graphite iron set.

I am not familiar with the Hypersonic brand of shafts. Have you had good success with them?
Question by: Richard Dutcher on Mar 16, 2022, 12:31 PM
The SK Fiber brand (formerly Fiber X) has served custom clubmakers since the early '90's. While not a household name, they have been proven to make very good shafts that are affordable with tight tolerances.

this is my 1st time with the SK Hypersonic iron shaft in R/S flex. Are there trimming instructions for R vs S flex?
Question by: ROBERT LEIGHTON on Sep 24, 2020, 7:02 AM
Yes, there are trimming instructions for each flex. If you are on the product page, you can look down at the specification box and you can hyperlink to the correct flex. For R-flex it is chart IH7 shown here: https://www.hirekogolf.com/trimming-charts#R:_IH7

For S-flex, scroll down to trim chart IH10.

WHAT SHAT DIAMETER DO HYBRIDS USE ?
Question by: frank cannizzaro on Oct 6, 2020, 10:35 AM
Unfortunately there is no universal answer for that. All Hireko's hybrids require a 0.370" parallel tip shafts. But if you look across the industry you may run into 0.355" taper tip and 0.335" tip diameters as well.
Answer by: Jeff Summitt on Oct 8, 2020, 11:29 AM
Has Hireko published DSFI and Deflection numbers for the current SK Fiber shafts? Reading through the DSFI shaft fitting addendum on Hireko's website, I can only find older SK Fiber shafts.

Question by: David S on Jun 24, 2022, 11:28 PM
We haven't updated the DSFI addendum since 2019. We actually have a different tool we use to measure the stiffness of a shaft that wasn't available when we first started the DSFI and haven't had a chance to share that with customers.

    High Tech at a Reasonable Price
    I am a senior that needs a lot of flex. These counter balanced shafts allowed me to tip to a lady's flex and a men's standard length paired with concave iron hybrids for a swing weight of D-0. A smooth easy swing allows the flex of the shaft to produce effortless consistency. The high trajectory allows for accurate approach shots.
