Crosswind front wheel performance
- X axis: Crosswind at different degrees. The degree to which the wind arrives from the left or right side is defined in degrees as the Crosswind (yaw) angle [°]. The negative numbers represent the degrees the wind is coming from the left side, the positive numbers represent the degrees the wind is coming from the right side.
- Y axis: Aero Drag measured in watts
- Base drag: Defined by Swiss Side at 15 Watts, it is not a standard
- Thrust: Negative drag
- Sailing effect: The effect describes a “push” forward which happens when the wind comes from the side = crosswind.
- We compared different rim depths of the Swiss Side Hadron2 front cycling wheels: 500 mm (grey), 625 mm (blue), and 800 mm (red).
Crosswind front wheel stability
- X axis: Crosswind at different degrees = Crosswind (yaw) angle [°]. The negative numbers represent the degrees the wind is coming from the left side, the positive numbers represent the degrees the wind is coming from the right side.
- Y axis: Steering moment in Newton meter
- The front wheel steering moment is the force that a cyclist feels in the handlebars when crosswinds hit the front wheel. Through our research and extensive testing, we have determined that the characteristics lead to a stable and confident feeling from the front wheel. The graph shows a linear steering moment curve without sudden change at the stall point. The stall point is when the wind angle is too high, and the airflow can no longer stay attached to the wheel.
