Fast, faster, fastest! When every second counts. Absolute maximum aero performance for time trial and triathlon, with light weight and high stiffness. The HADRON³ Disc.
Wheel Tire System
Tubes and tyres are already pre-mounted.
Continental GP 5000 S TR 30mm rear tyre. Best in class rolling resistance, grip and puncture resistance.
Save €100 when ordering the front and rear Wheel Tire System.
Further reduced drag in a straight line and enhanced sailing effect in the wind. The rear DISC wheel uses an asymmetrical lenticular shape that is hollow inside, with twin foam sandwich outer walls for minimum weight, maximum stiffness and optimum power transfer. UCI approved.
Shimano 10 - 13 speed, SRAM 10 & 11 speed freehub as standard
SRAM 12- and Campagnolo 10 - 13-speed groupset options available separately
Safety notice
The maximum total system weight (bike + rider) for the HADRON³ Ultimate disc brake wheelset is 110kg.
Tyre pressures for the disc brake, tubeless 102psi should not be exceeded.
Tyre pressures for the disc brake tube tyre 123psi should not be exceeded.
Axle size
Axle size disc brake: 12/142mm TA, CTR-lock
Tyre recommendation
All tyres from 25mm to 64mm can be used on this rim. For optimal aerodynamic performance, we recommend using a 25mm tyre on the rear disc. If additional comfort is desired, a 28mm tyre can be used.
Not included:
Disc rotor
Brake pads for disc brake
Trough axle
Wheel 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
HADRON³ Ultimate DISC
The three dimensions of performance
Lower Base Drag
The specially tuned V-Shape profile is more aerodynamic and creates less losses in the airflow. Despite wider rims, with a larger frontal area, the V-Shape profile reduces the ‘base drag’.
Best-in-class handling
The rider’s body is ~70% of the drag of the bike-rider system. Good handling wheels not only save drag themselves, but can save drag on the rider. This is where even bigger savings can be made.
Keeping the rider confidently in the aero position, in gusty wind conditions or on high-speed descents simply makes them faster. So best-in-class handling has and remains a key characteristic of Swiss Side wheels.
‘Dual Performance’ // Wheel-tyre-System Tuning
When some wind is present, the Continental AERO 111 tyres maximise overall performance through enhanced sailing effects and the lowest possible aerodynamic drag, without compromise on handling.
In calm wind conditions or in high-speed time trial riding, where the yaw angle remains low, and the cross-wind aerodynamic performance / sailing effects play a reduced role, riders can switch to lower weight and lower rolling resistance tyres (e.g. Continental GP5000 TT TR) for unmatched efficiency.

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.
