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."
