Selecting the right flex for your golf club shafts is key to getting the most out of your clubs. Shafts come in five flex categories: extra stiff (X), stiff (S), regular (R), senior (A) and ladies (L). Generally, the faster your swing the speed, the stiffer the shaft you will need.
Visit a golf store or fitting professional to have your swing evaluated. A professional will be able to assess your swing and speed and recommend the proper flex.
Extra-stiff flex may be used by golfers who consistently hit the ball 300 yards off the tee. This shaft is generally reserved for professional golfers.
Stiff flex may be used by golfers who consistently drive the ball 250 yards. This is one of the two most popular stiffnesses and is usually used by mid-low handicappers.
Regular flex may be used by golfers who consistently drive the ball between 225-250 yards and is also a very popular selection. This stiffness is appropriate for mid-high handicappers.
Senior flex may be used by golfers who consistently drive the ball between 200-225 yards and is a popular selection with older, male golfers.
Ladies flex may be used by women and those who consistently drive the ball less than 200 yards. This is the softest flex available.
