Bicycle manufacturers and dealers in several countries in Eastern Europe and elsewhere are being given the opportunity to participate in Shimano’s “Reliability Campaign,” related to quality certification of bicycles manufactured with Shimano parts. The brand gives silver status to bicycles that use certain high-quality Shimano components, and gold status to those that use more of them. A dealer will have to fill in a Shimano «service book» for each certified bicycle that is sold to consumers, tracking down the maintenance it has undergone. It will help raise the value of a bicycle if it is resold and it will serve as proof of ownership if it is stolen. New participants have signed up from the following countries, many of which are serviced by a regional distributor: Bulgaria, Romania, Serbia, Slovenia, Macedonia, Greece, Turkey, the Czech Republic, Hungary, Poland, Slovakia, the Ukraine, Portugal and South Africa.
