At Swiss Side, our mission has always been clear: to deliver robust, quantifiable performance benefits for every cyclist. The launch of our new HADRON³ wheel series—including the HADRON³ Ultimate and HADRON³ Classic models—is the culmination of this philosophy. These wheels aren't just an evolution; they're a new benchmark in cycling performance. So, what exactly sets the HADRON³ series apart?

The "Deeper, Wider, Lighter" Philosophy

The HADRON³ series is built on a fundamental principle: a wheel must be deeper, wider, and lighter to be truly faster. We’ve meticulously re-engineered the rim profile to achieve this.

Deeper: The new V-shape rim profile is deeper than previous models, which significantly reduces "base drag" at low yaw angles (frontal airflow). This translates to class-leading aerodynamic efficiency, providing crucial time savings when you need them most.

Wider: With a new 22mm inner rim width, the HADRON³ wheels are optimised for 28/29mm tyre sizes. This wider profile not only improves aerodynamic performance but also enhances stability and comfort, giving you the confidence to push harder.

Lighter: Thanks to advanced manufacturing methods like the DT Swiss "direct out of the mould finish," the HADRON³ Ultimate line is lighter than ever before. A reduced spoke count on the front wheel further minimises both weight and drag, ensuring you accelerate faster and climb more efficiently.

Best-in-Class Handling and Stability

A fast wheel is useless if it's not stable. Through extensive research and wind tunnel testing, we've fine-tuned the HADRON³ wheels to offer predictable and stable handling, especially in crosswinds. The wheels are designed to maintain a linear steering moment, meaning you won't experience sudden or unpredictable changes in handling, giving you the confidence to stay in an aerodynamic position for longer periods.

The Dual Performance Wheel-Tire System

The HADRON³ wheels introduce a unique "Dual Performance" tuning option, a first in the industry. This allows riders to optimise their setup based on race conditions.

For high-speed time trials or calm conditions, riders can pair the HADRON³ wheels with a lightweight, low-rolling-resistance tyre (e.g., Continental GP5000 TT TR). This combination maximises efficiency by leveraging the wheel's reduced base drag with a thin-carcass tyre.

For races with strong crosswinds, we recommend pairing the HADRON³ wheels with the Continental AERO 111 tyre. The AERO 111's patented tread pattern works in harmony with the HADRON³ rim profile to maximise the "sailing effect," delivering a significant aerodynamic advantage and enhanced stability.

A Wheel for Every Rider: Ultimate vs. Classic

The HADRON³ series is available in two distinct lines:

• HADRON³ Ultimate: Engineered for maximum performance with deeper rims, lightweight construction, and top-tier components like Swiss Side-specific DT Swiss 180 Aero hubs and SINC ceramic bearings.
• HADRON³ Classic: Offers the same advanced rim profile as the Ultimate but with a more cost-effective build, featuring reliable DT Swiss 370 Classic Aero hubs. This ensures that Swiss Side's signature aero performance is accessible to a wider range of riders.

In essence, the HADRON³ wheel series stands apart by delivering a complete, optimised package of aerodynamics, weight, stability, and versatility, all backed by a transparent, data-driven development process. They are not just faster; they are better in every dimension.
