Twalcom - Steel Rear Sprockets (BMW G650X Challenge)
High quality of materials has always been imperative in choices affecting the designing and manufacturing of chain pinions and wheels by CHT Chiaravalli. We know that a winner product demands that high quality raw materials be employed, and that is why we select them with utmost care and we process them with the most advanced systems, depending on the specific product and on the burdensome task that it is going to serve in terms of safety and performances. Our choices have been rewarded with years of successes, but evolution is unending: the study of new raw materials and of new thermic and superficial treatments is already under way to allow us to preserve our technological leadership.
