摘要:
A multi-speed sprocket assembly is suggested, including at least a larger sprocket and at least a smaller sprocket. The smaller sprocket has a trailing tooth which is last to engage the chain before moving onto the larger sprocket. The larger sprocket has a leading tooth which either is the first to engage between a first outer link plate pair of the chain or is located adjacent to a first inner link plate pair of the chain. At least the larger sprocket has an upshift transitional region which has a double spacewidth created by omitting a tooth and is immediately followed by the leading tooth. In the region of the double spacewidth, the larger sprocket is embodied in such a way that a crossing chain link comes into contact with the larger sprocket only in the region of the leading tooth.
