Überragend (Paramount in english) this is how the Sine Thesis was judged by Germany’s Road Bike magazine in their May 2011 issue. The Sine Thesis was elected best helmet out of 18 models from 16 different brands. The measurements of the helmet’s capacity to keep the head cool left no chance to the competition and the Sine Thesis came out logically as the “best package” of all the helmets tested.
