With Speed Regime, a unique HEX Aerodynamics profile and overall construction of each golf ball maximizes its performance based on what each swing speed range needs to achieve the most distance and the best performance.

SEVEN QUESTIONS: CALLAWAY SPEED REGIME GOLF BALLS

What are the basics details for the new Speed Regime golf balls, and when can I try them?

Speed Regime is a new series of tour golf balls from Callaway Golf. There are three unique golf balls: SR 1, SR 2 and SR 3, and each has been developed for optimal performance based on a golfer’s swing speed.

As for trying them, Callaway encourages trial on-course, because their testing shows that these balls fly farther.

Talk to me about designing golf balls based on a golfer’s swing speed?

There will be three Speed Regime golf balls available: SR 1, SR 2 and SR 3.

SR 1 is for swing speeds of 90mph and below
SR 2 is for swing speeds between 90mph and 105mph
SR 3 is for swing speeds of 105mph and above

Golfers that swing 85mph need different performance characteristics from a tour level ball than a golfer that swings 108mph. So Callaway has designed a unique HEX Aerodynamics package for each Speed Regime ball, and have constructed each ball to perform best based on a defined range of swing speed.

How is the SR 3 – for golfers with a swing speed of 105mph or higher - different from the others?

Callaway designed a HEX Aero profile for SR 3 to reduce drag at high speeds. At the start of a golf ball’s flight - just off the tee when it is experiencing its highest speed - drag forces dominate at those ball speeds. So Callaway wanted to minimize the drag as much as possible during that time and designed the aero profile to do that.

That is critical for the 105mph and above player, but that emphasis on minimizing drag in the first stages of ball flight is not as meaningful to swing speeds below 105mph.

Callaway managed to do so in the SR 3 without sacrificing the low speed lift that is needed later on in the ball flight (after the apex).

And the SR 2 (for golfers with swing speeds beteween 90 – 105)?

Aerodynamically Callaway designed this ball to have the best balance of low drag at high speeds (at the very start of the flight when the ball is going the fastest), and good lift at low speeds (at the end of the flight when the ball is descending).

Together, if you balance that right, which Callaway were able to do in SR 2, you get longer distance and an incredible overall ball.

So how is SR 1 – for golfers with swing speeds of 90 and below – different from the others?

Because at this range of swing speed the golf ball doesn't achieve very high speeds so the need to design specifically for low drag goes away.

Instead Callaway focused the aero package on lift at lower speeds toward the end of the flight when the ball is descending.

With SR 1, Callaway want to keep the ball in the air longer to make it fly farther.

What specifically differentiates in each aero package? How does the underlying construction impact performance of each?

The aerodynamic profile for each of the Speed Regime balls is a function of surface geometry (shape, tube height, and other such scientific things) designed in combination with the cover material.

Speaking of which, the three Speed Regime balls also have different cover materials that contribute to their overall performance.

All three balls have urethane covers for great spin, but SR 1 has the softest and SR3 the firmest.

When asked about the underlying construction, Callaway’s head of golf ball R&D, Dave Bartels, says:

“Each of the Speed Regime balls is designed with a dual core for optimal spin separation and a durable urethane cover for Tour-Level control around the greens.

"The specific materials and composition that make up these balls are designed to have great feel and overall performance, optimised to provide the longest distance for players within their Speed Regime.”

Does this signal a new golf ball R&D philosophy for Callaway?

Callaway has always put the golfer benefit first in our ball designs, but the more custom fit focused approach with the Speed Regime balls has allowed the team to emphasize certain performance benefits to give golfers even more distance and better overall performance.

Callaway also realise how challenging it can be for golfers to find the ball that best suits their game, so Callaway has tried to simplify the selection with the Speed Regime lineup.

If a golfer can estimate their swing speed they can be assured that the Speed Regime ball they select will be the best performing ball for them – with great spin around the green, great feel, and LONG!
