bearing this stamp may be used. Exceptions to this are a very limited set of equipment including carbon wheels, tires, stems and saddles used in Girls' Keirin, which can be used without NJS certification. The NJS standard is to ensure that no rider will have any advantage or disadvantage based on equipment and does not necessarily relate to quality or standard of manufacture. For example, 36 spoke wheels are allowed but not 32, although 32 spoke wheels are typically lighter, and frames must be built by a very limited number of approved builders. Since its beginning, the bicycle frames used in Keirin races have been made from chromoly steel. Exceptions to this are frames used in Girls' Keirin, and Keirin Evolution races, where the frames used are made from carbon-fiber. Manufacturers of the frames used in Girls' Keirin are Boma, Bridgestone, Gan Well, Kalavinka, Bomber, and MBK. Participants in Keirin Evolution races may use any NJS, UCI or JCF approved carbon frame and components. NJS approved equipment often sells for more than comparable equipment because of its specific use, build requirements, and limited manufacturers. Popular manufacturers include Nagasawa, 3Rensho, Makino, Kalavinka, Level, Bridgestone, Panasonic, Samson, Shimano, Nitto, Hatta, MKS, Kashimax, and Sugino. Because the NJS's main objective is supporting the Japanese cycling market, its bureaucracy is notoriously critical of foreign manufacturers attempting to enter the Japanese market. The Italian cycling equipment manufacturer Campagnolo has, though, received NJS certification. NJS-approved equipment is not required for keirin races sanctioned by the Union Cycliste Internationale or its local national sporting associations, including UCI-sanctioned races in Japan. Betting Bets that can be made on Keirin races include, but are not limited to: – selecting the first two finishers in exact order – first two finishers in any order – first three finishers in exact order – first three finishers in any order - selecting two to finish in the top three, in any order. Some wagers cannot be placed if there is a small number of competitors in the race. During major race meets, some jackpot wagers are offered: Dokanto! 4 two – selecting the first and second-place finisher in each of the last four races of the day. Dokanto! 7 – selecting the winner of each of the last seven races of the day. The money bet into the Dokanto wagers can carry over if there are no winning tickets, even to subsequent
