These S2S Graphite Golf Shafts are the most precise in the golf industry. They are measured using a Shaft Bend Profile as shown in the chart to insure precision in feel, trajectory and consistency. The measurement is in cycle per minute to measure shaft stiffness. Each shaft (Regular Flex and same shaft weight) has distinct variances that will help golfers achieve the proper flight for each golfer. Does your shaft provide this information? NO.
