Callaway has introduced its Speed Regime golf balls, based on the various swing speed of golfers.
SR 1 is for swing speeds of 90 m.p.h and below, SR 2 is for swing speeds between 90 and 105 and SR 3 is for swing speeds of 105 and above.
Callaway has designed a unique HEX Aerodynamics package for each Speed Regime ball.
The HEX Aero profile for the SR 3 is designed to reduce drag at high speed, particularly at the beginning a golf ball’s flight off the tee when drag forces dominate.
Callaway has designed the SR 2 to have a balance of low drag at high speeds and good lift at low speeds at the end of the flight when the ball is descending in order to provide longer distance.
The aero package in the SR 1 is focused on lift at lower speeds towards the end of the flight to keep the ball in the air longer for more distance.
The aerodynamic profile for each of the Speed Regime balls is a function of surface geometry (shape, tube height, etc.) combining with the cover material.
The three Speed Regime balls also have different cover materials that contribute to their overall performance., All three balls have urethane covers for better spin, but SR 1 has the softest and SR3 the firmest.
“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,’ said Dave Bartels, head of golf ball R&D for Callaway.
“The specific materials and composition that make up these balls are designed to have great feel and overall performance, optimized to provide the longest distance for players within their Speed Regime,” he added.
