1. A hold and release mechanism for holding and releasing a cable take-up device of a bicycle shifter for holding an actuation cable in a plurality of actuation positions with the cable take-up device, the plurality of actuation positions including a maximum pull-out position to a maximum pull-in position, the hold and release mechanism step-by-step releasing of the actuation cable in a release direction, the hold and release mechanism comprising:
a toothed-disk arrangement coupled with the cable take-up device for rotating together about a first axis, the toothed-disk arrangement including a plurality of teeth at an outer periphery thereof, the plurality of teeth including locking and safety teeth, the locking teeth disposed in a first tooth plane orthogonal to the first axis, the safety teeth disposed in a second tooth plane that is orthogonal to the first axis and offset relative to the first tooth plane; and an adjustable locking pawl pivotably mounted about a second axis, the adjustable locking pawl including locking and safety catches, the locking catch engaging with one of the locking teeth for holding the toothed-disk arrangement in a first rotational position, the safety catch engaging with one of the safety teeth for holding the toothed-disk arrangement in a second rotational position, the first rotational position corresponding to one of the plurality of actuation positions of the actuation cable and the second rotational position corresponding to intermediate positions of the actuation cable when the actuation cable is transitioning between adjacent ones of the plurality of actuation positions when releasing the actuation cable. |
