US Patent 11643167 Multi-sprocket arrangement

A multi-sprocket arrangement for a bicycle includes a larger sprocket having a passage recess on an outer link plate passage tooth on an outboard side of the larger sprocket facing a smaller sprocket. The recess is on a side of the larger sprocket facing the smaller sprocket. The passage recess extends from a radially outer tooth tip of the outer link plate passage tooth to a non-load tooth flank of the outer link plate passage tooth or a tooth base directly adjacent to the outer link plate passage tooth such that during a gear shifting of a chain from a larger sprocket to a directly adjacent smaller sprocket, the chain passes the outer link plate passage tooth on the outboard side of the sprocket.
