The current issue of German Tour-Magazin (issue 10/2017) features a test of 22 carbon disc clincher wheelsets, that are facing off in the categories aerodynamics, crosswind stability (both tested in the wind tunnel), weight & acceleration, stiffness as well as impact resistance.
Our ax Ultra Disc 45C has demonstrated its outstanding class here by earning the test topping rating of 2.1:
"Very light yet with resilience. The rim remains without damage in the crash test. Build and mechanical values are very good."
