Multiple Flex Shaft System for Golf Clubs

Abstract

The present invention relates to methods for optimizing the flexibility of each shaft comprised in a set of golf clubs. In general, based on a golfer's estimated swing speed, skill level and/or other relevant factors, an appropriate category of golf club shafts is selected. Each category of golf club shafts employ a unique range of shaft flexibility. The range of flexibility exhibited by categories of golf club shafts optimized for golfers with relatively higher swing speeds is greater than the range of flexibility exhibited by categories of golf club shafts optimized for golfers with relatively slower swing speeds. Similarly, the range of flexibility exhibited by categories of golf club shafts optimized for golfers of relatively higher skill levels is greater than the range of flexibility exhibited by categories of golf club shafts optimized for golfers of relatively lower skill levels.

1 . A method for optimizing the flexibility characteristics of each golf club shaft in a set of golf clubs, wherein the method comprises the steps of: 
 (i) providing a plurality of golf clubs having shafts;    (ii) determining a flexibility of the shafts;    (iii) grouping the golf clubs into a plurality of sets of golf clubs based upon the flexibility of the shafts and a difference between the flexibility of the shafts within the plurality of sets of golf clubs;    (vi) determining a golf club swing speed of a golfer; and    (v) selecting an appropriate one of the plurality of sets of golf clubs for the golfer based on the swing speed of the golfer.
