Abstract: A bicycle sprocket assembly has a first sprocket with a plurality of first radially protruding portions, a second sprocket with a plurality of second radially protruding portions and a sprocket support member. The second sprocket has more teeth than the first sprocket. The sprocket support member includes a plurality of sprocket mounting portions extending radially outwardly from a freewheel engaging portion. Each of the sprocket mounting portions has first and second sprocket mounting openings for fixing the first and second sprockets, respectively. The first sprocket mounting opening is circumferentially offset from the second sprocket mounting opening with respect to a center rotational axis of the sprocket assembly. The radially innermost edge of the second radially protruding portion is spaced by a radial distance that is smaller than a radial distance of the radially outermost edge of the first sprocket mounting openings with respect to the center rotational axis.

Abstract: A bicycle sprocket assembly is provided with at least a first sprocket, a second sprocket and a first axial spacer. The first sprocket includes an outermost peripheral portion defining a plurality of first teeth, and an innermost peripheral portion defining an opening that is free of any freewheel engaging splines. The first sprocket is larger than any other sprocket of the bicycle sprocket assembly. The second sprocket includes an outermost peripheral portion defining a plurality of second teeth, and an innermost peripheral portion defining an opening having a plurality of freewheel engaging splines. The first axial spacer is fixed to the first and second sprockets such that the first axial spacer is disposed between the first and second sprockets without any intervening sprockets disposed between the first and second sprockets. The first axial spacer includes an innermost peripheral portion defining an opening having a plurality of freewheel engaging splines.
