HADRON³ Classic

Same rim tech. More accessible build. The HADRON³ Classic uses the same new-generation rim profile as the Ultimate series, tuned for lower drag and improved handling. Paired with Swiss Side Aero hubs based on DT Swiss 350 internals, it offers proven aero performance and reliability. The best starting point for serious speed.

Lightweight and robust construction, without neglecting aerodynamic performance.The HADRON² Classic 380 is engineered for the steepest climbs of the Swiss Alps. UCI approved.

Low weight. High performance. Compact rim depth with excellent aero efficiency. The HADRON³ Classic 550 is ideal for mixed terrain, climbing courses, and variable conditions. Shares the same advanced rim shape as the Ultimate, combined with a reliable, cost-efficient hub and spoke system.

Balanced aero. Everyday race-ready.The HADRON³ Classic 650 hits the sweet spot for all-round racing and training. Optimised for speed and control in all conditions, with proven aerodynamics and predictable handling. A versatile setup for triathlon, road racing, or fast endurance riding.

Deep aero performance. Accessible build. For maximum aero benefit on flat and fast courses. The HADRON³ Classic 850 delivers low drag and stable handling in a deep-section format. Built around DT Swiss 370 Classic Aero hubs and Aerolite-I spokes . Race-level performance at a more accessible price.

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.

Swiss side aerodynamic wheels crosswind front wheel performance measurements

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 Classic

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.
