摘要： The chain guide of a bicycle rear derailleur is a chain guide which is connected to a movable member so that this guide is free to swing about a center pivot axis. The chain guide has a pair of plate members rotatably supporting a guide pulley and a tension pulley. One of the plate members is provided with a chain slip prevention part which is disposed between both plate members in the vicinity of the guide pulley. Preferably, the chain slip prevention part has a width of ten mm or greater and fifty mm or less.

摘要： A bicycle rear derailleur is basically provided with a base member, a movable member and a moving mechanism. The movable member pivotally supports a chain guide. The moving mechanism is coupled between the base member and the movable member so that the movable member is movable relative to the base member. The chain guide includes a first guide plate, a second guide plate, a guide pulley rotatably disposed between the first and second guide plates and a tension pulley rotatably disposed between the first and second guide plates. The first and second guide plates are releasably coupled together by a tool-less connection.

摘要： A bicycle rear derailleur basically comprises a mounting member, a movable member, a connecting mechanism and a chain guide. The chain guide includes a first plate member, a second plate member, a guide pulley and a tension pulley, with at least one of the first and second plate members including a chain disengagement prevention part arranged between the guide pulley and the tension pulley. The chain disengagement prevention part is arranged to make it more difficult for a chain disengagement prevention part provided on a chain guide to become jammed in a sprocket.

摘要： A bicycle rear derailleur comprises a base member, a movable member, a linking member coupled between the base member and the movable member so that the movable member moves laterally relative to the base member, and an extension member having a movable member coupling location coupled to the movable member and a guide pulley coupling location offset forwardly of the movable member coupling location. A guide pulley is coupled to the extension member at the guide pulley coupling location for rotation around a guide pulley axis, and a tension pulley is coupled to the movable member below the guide pulley. The guide pulley and the tension pulley are not directly attached to a same member.
