Abstract
A plurality of sprockets which are coaxial with respect to a sprocket rotation axis, are arranged with axial spacing from each other and have different numbers of teeth which are constructed for positive-locking engagement with a bicycle chain. The pinion arrangement has a gear range quotient which is formed by division of the number of teeth of the sprocket having the largest diameter by the number of teeth of the sprocket having the smallest diameter, and has a packing density quotient which is formed by division of the number of sprockets in the sprocket arrangement by the axial spacing measured in millimeters of the axially outermost pinions from each other. The pinion arrangement may have a gear range packing coefficient, formed from the product of the gear range quotient and the packing density quotient, which is greater than 1.25.
