Abstract:
A bicycle shift control device is provided with a shift winding member, a winding pawl, a winding member return element, a gear shifting mechanism and a winding pawl biasing element. The winding member is movably arranged between a rest position and a shifting position. The winding pawl moves in response to movement of the winding member. The winding member return element biases the winding member to the rest position and to bias the winding pawl to a pawl engagement position when the winding member is moved from the rest position towards the shifting position. The gear shifting mechanism includes winding teeth that are engaged with the winding pawl. The winding pawl biasing element applies a biasing force to the winding pawl that urges the winding pawl to the pawl engagement position when the winding member is in the rest position.
