Every Apollo
Professional Shaft has a spine where the rolled steel
meets a weakness in wall thickness. (Mass Produced
“Off the Rack” graphite shafts also have spines)
By locating the spine, it can be placed in a predetermined
position. CFC Golf finds the spine so we know exactly
where the shaft is going to flex, then position it
exactly right for the golfer and the club, from a
driver down to a putter.
Swing Science Professional shafts are the most popular
of our Swing Science shafts. The 200 Series offers
a full flex range in both woods and irons. Featuring
a light weight filament wound design, the 200 Series
generates high launch ball flight characteristics.
CFC builders chose this professional tour quality
shaft because of the consistency of this filament
wound design. See Below:

United States Patent 5259614
CFC Swing Science professional shafts are a composite
seamless filament-wound professional tour quality
shaft. The shafts include a hollow steel tubular
core and a filament such as steel, fiberglass, graphite,
or carbon, spirally wound around the core to form
a seamless jacket thereabout. The filament is impregnated
with an adhesive and permanently bonded to the core,
and the core may be torsionally stressed prior to
and during the winding thereupon and bonding thereto
of the filament. The shaft can be made as an overlong
blank universal shaft, then portions of the butt
and tip of the shaft can be trimmed to produce a
desired shaft length and natural frequency of vibration.
When attached to a club head, the head may be weighted
to produce a resulting golf club of desired swing
weight.
