摘要： An individual chain wheel for a bicycle front crank arrangement for engaging in a drive chain includes a plurality of teeth formed on a circumference of the chain wheel and having a first and a second group of teeth. The teeth of the second group of teeth are arranged in an alternating manner between the teeth of the first group of teeth. Each tooth has a load flank via which force is transmitted between an adjacent roller of the drive chain and the respective tooth. Each tooth of the first group may also have at least one profile with an opening in the vicinity of the flank, in which a portion of an inner link plate of the drive chain, which portion protrudes beyond the roller, engages.

摘要： 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.
