The auxiliary bicycle shifting component basically has a fixed part and a chain contact part. The fixed part is used to fix the chain contact part on the chain guide. The chain contact part is disposed on the chain-entry side of an outer plate of a chain guide of the front derailleur, and is configured and arranged to contact with a chain.
