Golf Shaft Kickpoint / Bend Profile / Bendpoint

From the Picture Above. The Top is where you hold the club(Grip) and the bottom is where the club-head is. If they are same FLEX, you can see they actually will launch the ball differently because the "bend point" is different.

"Kickpoint" is actually old term shaft design that was used to try to describe how the shaft's overall stiffness or flexibility was distributed over the entire length of the shaft. Today, It will be call Bend Point of Bend Profile.
The most important factor for different bend point result in the trajectory of the ball fly. The reason for that is from the construction of the shaft.
By varying the outer and inner diameters of the shaft, along with the wall thickness in-between at any point along the shaft, we can construct shafts of the same overall stiffness but which differ in where they are more or less stiff.
For example, the factory can produce two shafts both in R flex but with different bending point / bend profile.
Let's say we compare these two drivers:

1st Driver 9.5 degree with 65gram Regular Flex High Profile (Low Kick)

2nd Driver 9.5 degree with 65gram Regular Flex Low Profile (High Kick)


The 1st Driver will actually launch the ball higher due to the Profile of the Shaft.
(If the swing is exactly the same..)

Therefore, most of the drivers designed for Senior, Lady are most likely to have Lighter weight in shaft, softer flex, and higher profile.
Light Weight = easier to swing and can swing faster.
Softer flex = does not require fast speed of the swing.
Higher Profile = Launch the ball higher.

Distance come from the speed of the ball(Club-head speed at impact) and the carry distance(Ball travel time in air).
