A sprocket shift assembly wherein sprockets of different diameters are arranged as a cluster on a common shaft and are coupled with a chain between driving and driven members. The chain is movable as the sprockets rotate from one of the sprockets to another by realignment of portions of the sprocket such that the chain is at all times in a positive driving relationship with the cluster.
