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 cycles 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. The higher number of cpm, the stiffer the shaft will feel.

Shaft Flex	41" (Grip)	36"	31"	26"	21"	16"	11" (Head)
Regular (67 gram weight)	164 cpm	184 cpm	208 cpm	248 cpm	330 cpm	460 cpm	740 cpm
Regular (65 gram weight)	168 cpm	188 cpm	224 cpm	275 cpm	350 cpm	500 cpm	825 cpm
Regular (65 gram weight)	165 cpm	192 cpm	224 cpm	268 cpm	340 cpm	465 cpm	775 cpm
Regular (65 gram weight)	184 cpm	205 cpm	222 cpm	253 cpm	310 cpm	500 cpm	920 cpm

Shaft Selector Program

In the past, shafts were typically characterised by torque, flex and/or butt CPMs, however as shaft construction became more sophisticated, these designations became meaningless. Tom Wishon recognised this problem and began a series of experiments and research that led to the concept of a shaft’s “bend profile”. Dividing the shaft into a series of seven segments (points) and measuring the stiffness of that particular section by use of frequency meter meant that these frequencies could be plotted and the result was a ‘bend profile’ for the shaft, which empirically described the shaft’s stiffness.

Allows for matching swing moves to shaft stiffness profiles
Enables analysis of shafts with similar flex patterns
Predict adjustments in ball trajectory and flight
Removes the need to rely on traditional flex categories
Match the profiles of discontinued shafts with newer models Shaft Selector displays the bend profile alongside additional information such as tip diameter, shaft weight, and recommended swing speed to further assist the clubfitter in determining which shafts might be candidates for a particular golfer.
