Abstract on the basis of analyzing existing differ-ences between the Chinese made drum breaks of bicycles now available and the drum breaks of international fa-mous brand this paper carried out a great improvementon the available drum breaks from both breaking priuci-ple and structure by means of the thought of sgstematicengineering. Moreover,the structural parameters havebeen designed. to a further step and let its properties begreatly improved.New type of drum treak has alreadybeen successfully trial-manufactured and achieved a satis-factory effect.
