A bicycle chain is used to transmit the drive force to at least one chain wheel and contains chain rollers and inner and outer plates which are connected to each other by means of pins. As a result of a corresponding shaping of the extremely hard inner plate, the wear on the teeth which cooperate with the inner plate can be reduced on the chain wheels or sprockets.

A drive arrangement for a bicycle may include a plurality of sprockets arranged at a rear wheel of the bicycle. The sprockets may be particularly arranged to have a spacing that facilitates the configuration of an increasing number of sprockets in the plurality of sprockets. A singular front sprocket or chain ring may be used to drive the rear plurality of sprockets. The singular front chain ring may include first and second groups of teeth, the first group of teeth being wider than the second group of teeth. The drive arrangement may also include a rear derailleur. A chain having inner link plates with recesses may also be include in the drive arrangement.
