The utility model discloses a chain cover of an outer gearshift bicycle with a front derailleur, which is formed by adopting spray painting or injection after the iron sheet is stamped and can cover a chain wheel, a chain and a guiding plate of a front derailleur. A gap is arranged on the upper part of the chain cover near a chain shifting arm of the front derailleur so as to be convenient to peek the position of the guiding plate of the front derailleur from the gap for bicyclers in travel, and easy to adjust to a suitable place. The chain shifting arm is covered by a transparent cover above the gap. Thus, the utility model can not only prevent the trousers of bicyclers from staining by the oil stain of the chain and the chain wheel or from being entangled between the chain and the chain wheel, but also prevent the earth water and the silt spattered by the front wheel from staining the chain and the chain wheel so as to decrease the abrasion of the chain and the gear teeth.
