A roller-type chain for a bicycle is configured with asymmetrical chain link plates, the chain link plates applicable for use with a chain with reduced chain width as in use on chain drives with a high number of gear ratios. The chain link plates are configured at the inner side of the chain loop for engagement on the teeth of the rear sprocket and of the front chain wheel. The chain link plates are further configured at the outer side of the chain loop for interaction with the chain-guiding roller on the rear gearshift mechanism.

A drive arrangement for a bicycle may be provided with various interactive components configured to reliably and repeatably engage and disengage with one another both when new and after a period of wear. The drive arrangement may include a drive sprocket assembly connected to a driven sprocket assembly with a chain movable by a gear changer.
