A bicycle shift control device is provided which operates a shifting mechanism via a shift control cable, wherein the shift control device includes a control body rotatable about an axis for controlling the shift control cable, an operating body having an abutment in a position spaced apart from the control body and which is coupled to the shift control device for displacement between a home position and a shift position, a transmission including a plurality of ratchet teeth which converts the displacement of the operating body from the home position to the shift position into a rotational displacement of the control body, and an interface member movably mounted relative to the operating body. The interface member has an operating force receiving surface and an operating force applying surface, wherein the operating force receiving surface is adapted to receive an operating force from the rider, and wherein the operating surface applying surface applies the operating force to the abutment of the operating body for moving the operating body from the home position to the shift position.

An apparatus for operating a bicycle transmission shifting device having an operating component for mounting to a bicycle in close proximity to a brake operating unit for alternately pulling and releasing a transmission element, a first lever is mounted to the operating component for movement which causes the operating component to pull the transmission element and second lever is mounted to the operating component for movement which cause the operating component to release the transmission element. The first lever and the second lever are mounted to the operating component so that the brake operating unit is disposed between the first lever and the second lever when the shifting device is mounted to the bicycle. In order to be able to construct the shifting device with only a single pawl for the release mechanism the takeup element for the transmission element includes a control member having a plurality of large and small position retaining teeth for engaging the single release pawl.

A bicycle operating characteristic control apparatus includes a first bicycle component and a second bicycle component, wherein the second bicycle component is changeable from a first status to a second status. The first bicycle component includes a base member for coupling to a bicycle frame, a movable member coupled for movement relative to the base member, and a chain guide coupled to the movable member for guiding a chain among a plurality of sprockets in response to movement of the movable member. A biasing device provides a biasing force to the chain guide for tensioning the chain, and a rotation resistance changing device changes a rotational resistance of the chain guide relative to the movable member. The first bicycle component and the second bicycle component are operatively coupled so that rotational resistance of the chain guide changes in conjunction with a change of status of the second bicycle component.

A control cable fixing device is coupled to a bicycle component such as a rear derailleur in order to secure an inner wire of a control cable to the bicycle component. The control cable fixing device includes a support member with a first engagement surface and a cable fixing member with a second engagement surface. The cable fixing member is rotatable relative to the support member. The cable fixing member and the support member secure the inner wire between the engagement surfaces in response to rotational movement of the cable fixing member to a cable fixing position. The cable fixing member preferably includes a cam portion and a lever portion that is manually operable to rotate the cable fixing member.

A bicycle shift operating device basically has a base member, a shift wire take-up element rotatably mounted with respect to the base member and a shifting unit operatively coupled to the shift wire take-up element to selectively rotate the shift wire take-up element in first and second rotational directions about a pivot axis. The shifting unit includes a shift operating member pivotally mounted with respect to the base member along a pivotal path to operate the shift wire take-up element in the first rotational direction in response to pivotal movement of the shift operating member about an operating axis. The shift operating member is movably mounted with respect to the base member along a non-pivotal path to operate the shift wire take-up element in the second rotational direction in response to non-pivotal movement of the shift operating member with respect to the operating axis.
