发明名称 Front derailleur with independently movable chain guide plates
摘要 A front derailleur includes a base member for connecting to a bicycle frame, a first link pivotably connected to the base member at a first base member connection location, and a second link pivotably connected to the base member at a second base member connection location. An inner chain guide is pivotably connected to the first link at a first inner chain guide connection location and to the second link at a second inner chain guide connection location so that the inner chain guide moves laterally when the first link and the second link pivot relative to the base member. An outer chain guide is pivotably connected to at least one of the first link or the second link at a first outer chain guide connection location which differs from the corresponding first inner chain guide connection location or second inner chain guide connection location so that the outer chain guide moves laterally when the first link and the second link pivot relative to the base member.
