    • A bicycle sprocket is provided with a sprocket body and a chain engagement structure. The chain engagement structure includes sprocket teeth defining chain rollers receiving troughs. At least two consecutive ones of the troughs include a driven-side surface and a non-driven-side surface. The driven-side surfaces each have a first chain roller contact points corresponding to a first radius of a first minimum contact circle when one of the chain rollers is positioned to fittingly contact the driven-side surface. The non-driven-side surfaces each have a second chain roller contact points disposed at a second position corresponding to a second radius of a second minimum contact circle when one of the chain rollers is positioned to fittingly contact the non-driven-side surface. The first radius is larger than the second radius. The driven-side surfaces have effective concavities that are equal to or less than the curvatures of the chain rollers.

    • A bicycle sprocket assembly includes first, second and third sprockets. A first mounting portion of the first sprocket is directly connected to a second mounting portion of the second sprocket by first fasteners at circumferentially spaced apart locations. The first sprocket is supported on the second sprocket by the first fasteners and axially spaced from the second sprocket by the first fasteners. A second mounting portion of the second sprocket is directly connected to a third mounting portion of the third sprocket by second fasteners. The second sprocket is supported on the third sprocket by the second fasteners and axially spaced from the third sprocket by the second fasteners. First and second radially innermost ends of the first and second sprockets are radially spaced from and free from contact with a freewheel when the bicycle sprocket assembly is mounted to the freewheel.
