Abstract

The invention discloses a bicycle gear shifter, comprising: a base component, the base component has a first pivot axis; a shift pawl, a ratchet member, a positioning pawl, and the positioning pawl is held relative to the base component The release member is movably mounted between a position and a release position, the release member is movably mounted with respect to a second pivot axis offset from said first pivot axis, and the positioning pawl responds to the release operation of the release member to cause the positioning pawl to movement from the holding position to the release position; and a control member mounted for rotational movement relative to the base member between a first position and a second position in response to a release operation of the release member. The purpose of the present invention is to provide a bicycle gear shifter that avoids slipping or jamming, especially the gear shifting pawl not only acts when engaging the transmission teeth, but also acts as a positioning pawl during the release process It plays a holding role, reducing the material consumption of the gear-shift pawl and the positioning pawl.
