Multi-speed sprocket assembly
Abstract:
A multi-speed sprocket assembly configured to receive a bicycle chain including a plurality of pairs of inner link plates, a plurality of pairs of outer link plates and plurality of rollers connecting the pairs of inner and outer link plates. The multi-speed sprocket assembly generally includes a smaller diameter sprocket and a larger diameter sprocket rotated about a rotation axis in a driving direction. The smaller and larger diameter sprockets include first and second pluralities of teeth spaced about their peripheries, respectively. The larger diameter sprocket has an inboard side including first and second projections axially extending therefrom. The second projection is disposed circumferentially aft, opposite the driving direction, and radially outwardly of the first projection. The first and second projections simultaneously support one outer link plate as the bicycle chain shifts from the smaller diameter sprocket to the larger diameter sprocket.
