Terms & Definitions

Ball Speed - A measurement in miles per hour of how fast the ball is traveling immediately after it comes off the clubface.

Bend or Kick Point - The position on the shaft that exhibits the greatest amount of bending when the shaft is compressed at one or both ends. This reading is important because it helps determine ball trajectory. The lower the bend point the higher the ball flight. Likewise, the higher the bend point the lower the ball flight.

Bounce Angle - The measurement from leading edge to the ground. It allows the club to "bounce" off of the ground instead of digging in. This measurement applies mostly to wedges. The greater the bounce angle the more the club head can cut through tall grass and resist traveling too deeply into the sand.

Center of Gravity - The club head balance point that is controlled by the size of the club head and the location of the head weight. The lower the center of gravity – and the farther back it is from the club-face – the easier it is to get the ball airborne. • higher club speed will produce a longer shot upon solid contact. There is a direct correlation between club head speed and ball speed that is determined by how solidly the ball is struck.

Flex - Generally defined as the relative stiffness or overall bending property of a shaft. Manufacturers typically categorize shafts by regular, ladies, senior, firm, stiff and extra stiff flex.

Frequency - A more thorough, accurate, and precise way to measure the flex of a shaft. The frequency scale used by Hot Stix Golf is based on the length of the club as well as cycles per minute (CPM). CPM is measured by clamping the club at the butt end into the frequency monitor and measuring how many times the club passes a certain point over a given time. A frequency number of 8.0 is extremely stiff. 1.0 frequency is very soft.

Launch Angle - A measurement (in degrees) of how the ball comes off the club face.

Lie - The angle of a clubface and the corresponding steepness of the shot it will produce. Loft is determined by the angle of the face compared to 90 degrees to the ground.

Loft - The angle of a clubface and the corresponding steepness of the shot it will produce. Loft is determined by the angle of the face compared to 90 degrees to the ground.

Spin Rate - The spin rate is calculated by how many times the ball rotates in a given period of time. The unit of measurement is revolutions per minute (RPM). Spin rate directly affects how the ball flies through the air. A ball that is rotating faster, at a higher RPM, will stay in the air longer but not roll as much when it hits the ground. Conversely, a ball that is rotating slower — at a lower RPM, will not stay in the air as long. It tends to roll out further.

Swing Weight - Commonly, swing weight is known as the "feel" weight of the club. To determine the feel, simply hold the club up waist high and take notice how heavy the head feels. Some golf clubs will have a heavier swing weight than others by design. Variables in swing weight can result from length of the club, graphite vs. steel shaft, head weight, and grip weight.

Torque - The amount of resistance to twisting that a shaft has is called torque. Each shaft has a different torque, and it important to match the correct torque for your individual swing. The lower the torque number the less the shaft will twist when force is applied. This also will make the shaft feel "stiff".

Total Weight - The overall weight of a club after it is fully assembled is total weight. The lighter the total weight the faster the club can be swung.
