Wheels performance
At Swiss Side, transparency is the fundament of our goal to deliver exceptional value and make you fastest. We share the insights from our wind tunnel testing and extensive research, empowering you with the knowledge to achieve unparalleled speed and efficiency.
DEEPER. WIDER. LIGHTER.
- New lightweight construction thanks to DT Swiss ‘direct out of the mold finish’ manufacturing method for the Ultimate line, with the spoke count also reduced from 24 to 20 on the front wheel.
(Reduced spokes = less weight and less drag incl. less rotational drag) - Hooked-only rim construction
- No compromise on safety
- Maximum compatibility with tyre sizes and pressures
- New Swiss Side specific AERO hubs

The three dimensions of performance
Technical Development Paper
Get to know more about the performance of our HADRON³ Ultimate and HADRON³ Classic wheels.
Front wheel aero drag performance with crosswind
- 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 and HADRON³ front cycling wheels: HADRON² 38mm (blue), HADRON³ 55mm (green), HADRON³ 68mm (yellow), and HADRON³ 85mm (grey).
Front wheel aero stability with crosswind
- 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.
- We compared different rim depths of the Swiss Side HADRON² and HADRON³ front cycling wheels: HADRON² 38mm (blue), HADRON³ 55mm (green), HADRON³ 68mm (yellow), and HADRON³ 85mm (grey).
