Understanding Fitting Of Golf Clubs
When you are being fitted with golf clubs you are very much at
the mercy of the shop assistant. Having an understanding of how
a club is fitted, helps to ensure that you are being treated professionally
and have correct clubs for your physique, fitness and golf experience.
The key measures in golf clubs are:
- Lie Angle
- Loft Angle
- Swing Weight
- Frequency
- Spine Alignment
Lie Angle
The lie is an important factor in proper fitting.
Lie angles are described as too upright, too flat or correct.
A lie angle that is too upright will cause the ball to be hit left
of the target and a lie that is too flat, the ball will be hit right
of the target (for a right handed golfer).
Note: Not all irons can be adjusted more than 3 degrees.
Loft Angle
The loft angle is the angle of the face to the centerline of the
hosel. Higher lofted clubs result in a higher trajectory of the
ball. Loft angles are expressed in degrees with respect to vertical
rather than the ground.
Low Loft Angle Clubs: Drivers, 1 and 2 irons. Long distances at
low trajectory.
High Loft Angle Clubs: Sand and pitching wedges. Short distances
at high trajectory.
There is a natural progression in the loft of your irons from 1Iron
to the Pitching Wedge [PW]; determining the height of the trajectory
and distance you hit each iron.
Swing Weight
Swing weight is the relationship between the head weight, shaft
and grip weight. It is measured from the butt end around a 14 fulcrum.
Swingweight is a function of feel when choosing a set of clubs.
It is recommended you o use the lightest swingweight you are comfortable
with. For most players swingweights in the mid-C to mid-D range
is appropriate.
Swingweight is NOT total weight, however, generally, as shafts
get lighter swingweights also tend to decrease. A very heavy club
in real weight may only have a D-2 swing rate.
Longer clubs mean higher swingweights. Super long drivers (50+)
can get into E and even G swingweights.
Frequency Matching
Frequency is a method of dynamically determining the stiffness
or feel of a golf shaft. The frequency of a shaft is measured in
vibration cycles per minute [CPM]. A set of frequency matched clubs
has shafts with the same CPM readings.
Spine Alignment
The spine of a golf club shaft is the longitudinal plane that is
more resistant to bending than any other line or plane. The spine
is located and placed in a predetermined position. Every clubmaker
has their own preferred positioning, commonly 9 o'clock. The goal
of spine alignment is to aid repeatability via a stable plane.
