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.
