A multi sprocket arrangement is configured for mounting on a driver of a bicycle wheel. The multi sprocket arrangement includes a plurality of adjacent sprockets each of the plurality of sprockets having a different number of teeth. The plurality of adjacent sprockets include a first sprocket having a first inner diameter which is larger than an outer diameter of a profile base of a carrier profile of the driver, and a second sprocket having a second inner diameter which is smaller than the outer diameter of the profile base of the carrier profile of the driver. The first sprocket and the second sprocket are connected together by welding.
