Abstract
Derailleur with at least two sprockets on a sprocket unit, which is designed so that the chain can be easily shifted between a smaller sprocket and a larger sprocket. For this purpose, at least on the larger sprocket, there is a tooth space which forms a lane for the transfer of the chain between the two sprockets. By means of a side plate support ramp on the larger sprocket, a path of a chain transfer segment which is convexly bent or curved radially outward, viewed in the axial direction, is achieved, whereby the chain transfer segment is formed during the chain transfer from the smaller sprocket to the larger sprocket in the vicinity of the double tooth space.
