How do you measure a snowboard sidecut radius?
“Sidecut radius is the radius of the board between the two points of snow contact. If a board has a running length of 1000 millimeters and a sidecut depth of twenty millimeters than its radius would be 6,260 millimeters or 6.26 meters.
What is snowboard sidecut radius?
A sidecut radius is simply a term used to describe the total measurement of those sidecut depths and curvatures. To measure your snowboard’s sidecut radius, you’ll want to envision the arc of your sidecut turning into a full circle to one side of your board.
What is quadratic sidecut?
A quadratic sidecut uses 3 or more radii instead of a continuous radial or elliptical sidecut. The radii of the sidecut is shallower at the ends, and deeper in the middle. The shallower radius at the ends promote easy turn initiation and a faster exit at the tail.
What are the 3 numbers on skis?
Width dimensions All modern skis have a set of dimensions; three numbers that determine their width. For example, a ski might have this printed on it: 122-86-115. This means they have a width of 122mm towards the tip (the widest point), a waist width of 86mm (under the foot), and a tail width of 115mm.
What is the radius of a side cut snowboard?
Side-cut radius is a term used to explain the measurement of a side cut. Essentially what a side-cut radius is, is the radius (half the diameter) of a circle that would fit into the side cut of the snowboard. If the curve of the snowboard were to continue on to make a circle this is roughly the scale of what the circle would look like.
Why do you need a deeper side cut on a snowboard?
A snowboard with a shallower side-cut (a higher side-cut radius) will help the board to make longer smooth arcing turns. Generally speaking, and this is very generally speaking, freestyle or park riders like to have a deeper (smaller radius) side-cut in order to initiate sharper more abrupt turns and for spins.
How to calculate the sidecut of a Rossignol ski?
Sidecut = [(Tip Width + Tail Width) / 2) – Waist Width. 2. The sidecut of the aforementioned Rossignol, for example, comes out to 20mm. x = [(124 + 104)/2] – 74. 2. For a practical method, propping the ski’s edge on the floor and measuring the gap from the floor to the ski’s waist also shows sidecut.
How does the length of a ski affect the turn radius?
Turn Radius. Though a ski’s three width dimensions are basically consistent in varying length options, the length of the ski affects this arc. A longer ski creates a slightly longer turn radius. Therefore, manufacturers list a ski model’s turn radius at a particular length—such as 17 meters at a 180cm ski length.
