Best Golf Driver
The
C830.2 is the longest and best golf driver. Through optimizations of 4
design parameters: volume, moment of inertia, coefficient of restitution,
and center of gravity, Alpha has created a driver that has won more ReMax
World Long Drive titles than any other club. While many golf club
companies make the claim of having the world's longest and best golf driver,
only Alpha has the awards and titles to back it up.
Volume
The
C830.2 has the maximum volume allowed by the USGA at 460 cubic
centimeters. The large and
deep club head provides plenty of hitting area, and a center of gravity
deep inside the club (more on this later)
Moment of Inertia
The
moment-of-inertia (MOI) is the measure of resistance to club
twisting. The less a club twists before and during impact, the more stable it
is. And, therefore, the straighter and farther the ball goes. So a high
MOI driver promotes distance in off-center strikes.
There are
2 types of MOI - one affects twisting before impact and the other affects
twisting during impact.
The MOI
of the clubhead about its center of gravity is the first MOI metric which
determines clubhead twisting during impact. Alpha maximizes this MOI
by a variety of weight and geometry optimizations
that separate mass from the COG axis of rotation. This
is often called "perimeter weighting" in the golf industry.
The more
mass that is positioned away from the central axis, the less twisting
there will be. This lack of twisting promotes a very straight ball
flight - especially when the center of the ball is hit off from the center
of gravity axis.
The Alpha C830.2’s strategic heel-to-toe weighting increases the
rotational inertia to achieve this effect.
The MOI of the clubhead about the shaft axis is the second MOI metric
which determines clubhead twisting before impact. On the golfer's
downswing, the clubhead twists because of separation from the COG to the
hosel. Golfers with fast swing speeds choose stiff shafts so the
face angle can quickly recover to a square position right at the
tee. But the twisting can be mitigated by moving the COG close to
the hosel. In fact, the USGA regulates a minimum distance between
COG and hosel, and the C830.2 hits this exact limit.
Coefficient of
Restitution
The
Coefficient of Restitution (COR) is the measurement of how
"bouncy" an object is during impact. An object with a COR
of 1 collides elastically, bouncing perfectly with no energy loss. While
an object with a COR of 0 is said to collide inelastically, effectively
"sticking" to the object it collides with.
Mathematically,
it's measured as the ratio of velocities before and after an impact.
When thinking in these terms, it’s easy to see that a higher COR means a
faster ball speed after impact. And a faster ball speed means more
distance. The USGA limits COR to 0.83, and the Alpha C830.2 hits
this exact limit.
Alpha
engineers reach the maximum COR limit through 2 methods:
1) Using
the absolute highest grade titanium for the face - SP700 Titanium
2) A
super-thin face. A thin face provides a "spring-like
effect" where the face momentarily depresses at initial contact and
then "springs" back into shape at launch. If the face is
too thin, the driver can crack at high swing speeds. If the face is
too thick, you lose the spring-like effect where the face won't depress.
The right tradeoff of thickness for the particular type of titanium being
used is what keeps Alpha engineers busy in the labs.
Center of Gravity
The
Center of Gravity (COG) of a golf driver is the specific point at which
the club behaves as if all the driver's mass were concentrated. The COG is
located inside the head, and has 3 dimensions to it - X, Y, and Z.
The X-axis is the horizontal COG location (how far, left or right, it is
from the center of the club face). The Y-axis is the vertical COG
(how high it is from the sole of the head). And the Z-axis is the
COG depth (how far back it is from the face).
Golf
clubs obviously aim to keep the horizontal COG axis right at the center of
the club face.
Aligning the horizontal COG with the sweet spot of the club face
maximizes the Moment of Inertia - see MOI a few paragraphs
above.
For the
vertical COG, we want to keep this generally high to avoid topspin.
If the ball is hit above the COG, it launches with topspin which results
in a very poor ball flight. If the ball is hit below the COG, it
induces desirable backspin since the ball rolls up as it leaves the face
while the face twists downwards.
For the
Z-axis COG, we want it far back from the face without going too
deep. A deeper COG allows for more "dynamic loft" to get
the ball airborne. But going too deep reduces the MOI if the COG
gets close to the weight in the back of the head.
Positioning
the center of gravity vertically high, horizontally center, and back away
from the face is done by careful positioning of the weight. For example,
we add more weight on the crown of the head to raise the position of the
COG. We make the head shape deep so that more weight is positioned away
from the clubface, thus moving the COG back. And having the
largest volume allowed (460CC) also lets us maneuver the COG in the best
possible position.
Variable Face
Thickness
Alpha
Golf’s patented Increased Target Design (ITD) varies the thickness
across the face. By making the center of the face thinner and the outer
radius thicker, Alpha Golf engineers have created a giant sweet spot. Now
practically every drive is long and straight!

Construction
The 4
parameters to engineering a long distance driver are mostly scientific -
the Volume, MOI, COR, and COG can be optimized through computer-aided
design software. But there is also an art to club design. The
construction and manufacturing of a club head specifically for
long-distance drives requires some creative and unique solutions.
Most
off-the-shelf drivers are made with a 4-piece construction, gluing
together the face and body. They momentarily deform at high swing speeds,
resulting in energy loss. Alpha Golf’s plasma welding forges the SP700
Titanium face and the body at extremely high heat. Effectively acting like
a solid single piece on contact. Golf swings thus get virtually loss-less
impacts on every drive. Energy loss (through deformation or sound or
any other factor) is something the USGA does not measure or
regulate. At least not yet!
The
plasma welding does another thing - remember how we talked about moving
weight away from the face and towards the back of the club for optimal
center of gravity? Well the welding material that glues together a
4-piece construction contributes a few hundred milligrams to the overall
weight of the head. It is enough weight that removing the glue from
the face pushes the COG a few millimeters towards the back of the
club. Plasma welding eliminates this extra weight.
Plasma
welding is a much more expensive and time-consuming endeavor than
traditional club head construction. But this innovative manufacturing
process is one of the long-distance secrets behind the Alpha C830.2.
It is an art, but has scientific backing (and Re/Max World Long Drive
Titles) to justify the extra craftsmanship.
