Swiss Side’s HADRON² Classic range now completed with 625 and 800 options.

After launching the versatile and affordable HADRON² Classic 500 this spring, Swiss Side now extends the range with the deeper profile 625 and 800 models.

Using identical aero rims to the disc brake HADRON² Ultimate, the HADRON² Classic wheelsets feature the more cost efficient DT Swiss 370 hubs and heavier gauge aero spokes. The Classic range thus offer all the aero benefits of the Ultimate wheels, yet with an even stiffer construction and at a significantly lower price.

“Right from the very start, Swiss Side’s mission has been to offer elite aerodynamic technologies at a fair price,” says Jean-Paul Ballard, CEO of Swiss Side. “We are very happy to add the 625 and 800 models to our popular Classic range and bring new levels of speed and performance to determined cyclists and triathletes of all levels.”

New HADRON2 Classic 625: 

Delivering unprecedented aerodynamic performance with the widest operational range, the HADRON² Classic 625 is an excellent allrounder that handles superbly in medium to high wind conditions and rolling terrain. From training to racing, it is designed to deliver maximum speed and thrust in road cycling and triathlon.

New HADRON2 Classic 800: 

The pinnacle in affordable aero performance, the HADRON² Classic 800 is developed to generate untapped speed and maximum sailing effect in medium to low wind conditions. Ideal for time trial and triathlon racing.

Compared to the previous generation HADRON Classic range, the 2021 collection delivers a 10% reduction in aero drag and greater sailing effect. New technologies used in the aero development, including real-world wind studies with the Swiss Side CdA-meter, wind tower and pressure measurement rakes, have lead to even further improved stability in windy conditions. The wheels also feature an increased 20 mm inner rim width, thus accommodating wider tires and improving rolling resistance. HADRON2 Classic wheels are tubeless ready and available as disc brake only options.

All Swiss Side wheels purchases from 1st January 2021 include lifetime warranty for the original owner on material and workmanship defects, as well as our exclusive “Fair-Share Policy”.
