REAR SPROCKET ASSEMBLY

A rear sprocket assembly comprises a sprocket carrier, a first sprocket, and a second sprocket. The sprocket carrier includes at least one sprocket mounting portion having a first radial section and a second radial section. The first radial section has a first maximum axial length with respect to the axial direction. The second radial section has a second maximum axial length with respect to the axial direction. The second maximum axial length is larger than the first maximum axial length. At least one second mounted portion of the second sprocket is configured to axially contact the first radial section and the second radial section of the at least one sprocket mounting portion of the sprocket carrier with respect to the axial direction.
