    • Chain guides for the front sprockets of bicycles are disclosed. More particularly, the chain guides are adapted or configured for bicycles that have multiple (usually 2 or 3) sprockets/chain rings mounted to the crank assembly. The setup is provided to freely allow shifting between the gears. All of the chain guide variations presented are provided with an outer flange attached to a roller section so that these portions roll together with the chain they restrain. Additional optional features include aspects to do with roller positioning, bracket mounting, roller configuration and supplemental chain restrain means (including a stop/post member and inner roller flange.)
    • 公开了用于自行车的前链轮的链条导轨。 更具体地,链条引导件适于或构造成用于具有安装到曲柄组件上的多个(通常为2或3个)链轮/链环的自行车。 该设置被设置为可自由地允许齿轮之间的换档。 所有的链条引导件变型都带有连接到辊子部分的外部凸缘,使得这些部件与它们限制的链条一起滚动。 附加的可选功能包括与滚柱定位,托架安装,滚柱配置和补充链条限制装置(包括止动/柱塞构件和内滚筒法兰)有关的方面。
