Abstract
A chain tensioning device is basically provided with a main body, a chain guide, a rotary fluid damper unit and a rotational resistance adjustment device. The main body is configured to be mounted to a bicycle. The chain guide is pivotally coupled to the main body to rotate around a rotational axis with respect to the main body. The rotary fluid damper unit is operatively connected between the main body and the chain guide to provide rotational resistance to the chain guide around the rotational axis. The rotational resistance adjustment device is operatively connected to the rotary fluid damper unit to change a rotational resistance setting of the rotary fluid damper unit with the rotational resistance adjustment device in an operative state.
