Since golfers the world over do not swing the club at the same speed, Callaway has designed a unique new golf ball for optimal performance based on a golfer’s swing speed. Speed Regime is a new series of tour golf balls from Callaway featuring three unique golf balls: SR 1, SR 2, and SR 3. Golfers who swing the club at 85 miles per hour need different performance characteristics from a tour level ball than a golfer who swings at 108 mph. As such, the SR 1 is for swing speeds of 90 and below; the SR 2 is for swing speeds between 90 and 105; and the SR 3 is for swing speeds of 105 and above.
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 research and development 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, optimized to provide the longest distance for players within their Speed Regime.”
Within each Speed Regime the ball is optimized for drag (the force that occurs as the ball leaves the club face – drag occurs in the initial stages of ball flight) and lift (what keeps the ball in the air as it descends). Understanding the basics of lift and drag are essential to understanding the differences in the three different Speed Regime golf balls. “This is the first time we’ve had tour balls with zero compromise,” says Greg Sabella, Director of Golf Ball Marketing at Callaway.
Speed Regime golf balls are available nationwide with a retail price of $47.99 per dozen.
