ABSTRACT:
A chain engagement slot for bicycle sprockets, which enables a bicycle chain to be shifted from a smaller sprocket to a larger sprocket mounted next to it on a common cluster body. The chain partly enters the chain engagement slot, causing sufficient contact between the chain and the next sprocket tooth to enable the chain to be seated on the larger sprocket.
