Abstract: A multistage sprocket assembly for a bicycle comprises at least one larger sprocket and at least one smaller sprocket, in which both side surfaces of the larger sprocket are trimmed off at the positions corresponding to two downshifting paths and two upshifting paths designed for a drive chain when being shifted from the smaller sprocket to the larger sprocket or vice versa. The trim portion is large and deep enough to avoid any interference between the link plates of the chain and the larger sprocket, and to receive therein the link plates of the chain so as to provide a positioning function thereat during the chain shifting process.

Abstract translation: 一种用于自行车的多级链轮组件包括至少一个较大的链轮和至少一个较小的链轮，其中较大链轮的两个侧表面在对应于两个降档路径的位置处被修剪，以及为驱动链设计的两个升档路径， 从较小的链轮移动到较大的链轮，反之亦然。 修剪部分大而且足够深，以避免链条和较大链轮的链板之间的任何干扰，并在其中容纳链条的链板，以便在链条转换过程中提供定位功能。

Abstract: A cap includes a cavity for receiving the rounded tip of a nipple. The cavity narrows from an open end to a neck, and widens from the neck to a closed end. The neck forms an interference fit with the rounded tip, and the interference fit forms a sealed compartment in the cap that encloses an aperture in the rounded tip.

Abstract translation: 帽包括用于接收乳头的圆形末端的腔体。 腔从开口端缩窄至颈部，并从颈部变宽至闭合端。 颈部形成与圆形尖端的过盈配合，并且过盈配合在盖中形成密封的隔室，其包围圆形尖端中的孔。
