Ironman World Champion Wheels Review (HADRON Ultimate 800)

Triathlete Magazine took a close look at the Ironman World Champion Aero Wheels of Patrick Lange. Read the entire review in "The Championship Issue":

"Constructed in partnership with DT Swiss, using aerodynamic principles from F1 race cars, the Hadrons are a deep 80mm carbon clincher that tips the scales at 1,727g for the set. According to Swiss Sdie, these wheels perform best with high yaw angles - around 17 degrees - meaning they are faster with a moderate side wind. We also found them to be some of the most stable wheels in crosswinds at this depth, so it's no surprise these are an excellent choice for the blustery lava fields of Kona - or those nightmare conditions at your "A" race."

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!"
