Product Reviews

HADRON Ultimate 625 Test & Review (March 2019)

With the launch of the updated HADRON Ultimate wheel series, Swiss Side has taken "The Next Step”. Cykelmagasinet has tested whether we have also taken it to the next level. Here the summary:  

On the highway, it becomes clear that it is at high speed, in relatively flat terrain, that these wheels with 62.5 mm high rims excel.

+ Supplied with the DT Swiss 240 hub and new aero spokes, Swiss Side has allegedly found ½-1watt per wheel in the wind tunnel. It may not sound like a lot, but is quite a considerable amount of optimization of a very fast wheel set.

Swiss Side has produced a package that is extremely well suited for racing and fast training at the Danish latitudes.

+ The HADRON Ultimate 625 weighs 1621 grams, clearly in the lighter end of the spectrum, without being among the extreme lightweights.

The wise use of the material makes the wheel set nice and stiff.

+ All Swiss Sides wheels are also available in disc brake versions for the same price.

+ In normal side winds, the HADRON Ultimate 625 impressed us too. Only at a strong winds did things begin to get a bit uncomfortable. However, if you are a lighter rider you may consider the Ultimate 485 model, possibly just on the front wheel.

Swiss Side uses a completely flat price structure: for 1930 euro, you can combine front and rear wheels for the perfect combination.

Conclusion

Even though we regret that Swiss Side left the original idea of maximum aerodynamics at half price, Cykelmagasinet must acknowledge that Swiss Side with the HADRON Ultimate has manufactured a lightweight, stiff and fast wheel set, perfectly suited to Danish terrain. A wheel set that in all respects is in line with the more expensive competitors.

New Hadron Ultimate 625 - Test Review

Tritime Magazine has been testing the NEW 2018 HADRON Ultimate 625 aero wheels for a few weeks. Read what their editors had to say: https://www.tritime-magazin.de/2018/02/swiss-side-laufraeder-hadron-ultimate-und-classic/

"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.”

March 06, 2018

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.
