Rene Herse introduced his revolutionary cantilever brakes at the 1938 Concours de Machines. Their superlight weight was matched by excellent stopping power, something that was lacking from previous cantilevers.
Herse’s first version consisted of two aluminum plates, a design that later inspired the famous Mafac cantilevers used by generations of cyclocross racers. In 1945, Herse introduced his definitive model, with a fine-tuned geometry and a die-cast construction that allowed for even lighter weight. Herse’s brakes were not just for superlight bikes in the Concours; they equipped all his bikes and even tandems. Carefully equalized springs eliminate the need for tension adjustment screws, saving additional weight.
