ABSTRACT:
A derailleur for a bicycle, having a fitting member movably supporting a support carrying chain-guide pulleys through two parallel linkage members, is provided with a guard for the support and the linkage members, which guard is formed of an extension of the fitting member directed towards the support, thereby preventing the change-speed mechanism of the derailleur from being damaged when the bicycle is overturned.
