发明名称 Bicycle Front Derailleur with Mounting Structure and Bicycle Frame with Front Derailleur Mounting Structure
摘要 A bicycle front derailleur includes a mounting member, a chain guide, and a linkage assembly that pivotally couples the mounting member to the chain guide. The mounting member is configured to be mounted to a first frame member of a bicycle frame. The first frame member is pivotally connected to a second frame member of the bicycle frame about a pivot axis. The mounting member includes an attachment portion through which a fixing bolt for fixing the mounting member to the first frame member passes and includes an abutment configured to restrict rotation of the mounting member around the fixing bolt. The attachment portion is located on a front side of the pivot axis when the mounting member is mounted to the first frame member. The bicycle frame includes a structure for engaging and supporting the mounting member.
