New HADRON Ultimate 800 - Test Review

Check out the new Triathlon Magazine with a product review on the NEW HADRON Ultimate 800 aero wheels.

"The new HADRON Ultimate 800 aero wheel set, prooved to be very fast and stable during our test rides. After two month of riding the wheels they still look brand-new. The braking performance in wet weather, due to the carbon surface, is average. But there is also a disc brake version available. Interesting: You can mix and match the different rim depths. Also check out the HADRON Classic version of this wheel set, which is EUR 500 less expensive."

"Verdict after 1500km: A great wheel set with all options. Made in Europe!"

New Hadron Ultimate 625 - Test Review

"The first few hundreds kilometers felt already very promising. There is no weakness at all reading the stiffness of the wheels. Despite the cold and wet wether, we did not notice any deficits in braking performance. A more detailed test report will follow shortly.”

Long term test of HADRON Ultimate 800+ Aero Wheels

Jan Peiniger, triathlete, outdoor enthusiast, tech-nerd and star blogger tested the Swiss Side HADRON 800+ aero wheels for an entire year and wrote an extensive long term test report about the wheels.

Jan recommends the Swiss Side wheels to anyone that is interested in a high-end wheel set: "I only have good things to say about the HADRON Ultimate 800+ wheel set after riding them for an entire year. The wheels feel great and made it possible for me to finish the Ironman in Köln under 10 hours. Even in windy and difficult conditions the wheels stay very stable and manageable. You cannot go wrong with Swiss Side aero wheels. The price - performance is outstanding!"

Swiss Side HADRON Ultimate 625 (Triathlon Magazine August - 2017)

Triathlon Magazine Verdict:

The excellent handling of the wheel set and the outstanding aerodynamics make the Swiss Side HADRON Ultimate 625 aero wheel set a great choice for every triathlete! The rear wheel could be slightly stiffer. 

+ Great price/performance ratio

+ Very forgiving, comfortable and fast

+ Light weight 

+ Unbeatable in cross wind stability (most stable wheel set of entire test)

Swiss Side HADRON Ultimate 625 (Procycling Review August 2017)

"The aerodynamic experts at Swiss Side with longterm experience in Formula 1 racing are not only focusing on top aerodynamic performance and maximum sailing effect of their aero wheels, but also ensure steering stability when cross winds hit. 

This was proven during the test out on the roads. While riding the HADRON Ultimate aero wheels you feel the outstanding stability when cross winds hit. The wheels come with ceramic bearings as a standard for a price of EUR 1900/set. The rear wheel could be a little stiffer. This might be a compromise for the top aero performance of the wheels."

Swiss Side Hadron Ultimate 625 wheelset (Oct. - 2016)

Verdict: Very good overall rating. Fast, stable and a great performer. 

The Hadron Ultimate range from deep-section upstart Swiss Side takes a lot that we loved from the Hadron wheels (we've previously tested the 485 and the 625) and pimps it up with full-carbon rim construction and spanky ceramic bearings, as well as adding disc brake versions to the range. They remain a superb-handling deep-section wheel, now with a lower weight and a higher price.
