Light, but durable polyurethane for teeth and backing, high-tensile and, at the same time, longitudinally stable carbon for the tension member, plus a specially coated, wear-resistant fabric: the intelligent design with a combination of especially high-quality materials is a defining feature of the CONTI® SYNCHROCHAIN CARBON. It thus ensures clean, smooth and particularly reliable power transmission both at high torques and also with high dynamic loads.
