Abstract
A rear derailer for bicycles comprises a first body for fixing to the bicycle frame, a second body which carriers two chain-guide wheels and is connected to the first body by means which enable the second body to be displaced relative to the first body, a metal operating cable having one end fixed to the means for displacing the second body relative to the first body, and a cable-guide sheath provided at one end with a support element having a hemispherical end portion which is supported for rotation by a correspondingly-shaped seat formed in the first body. The support element is provided with a tubular extension for guiding the cable, the extension projecting from the hemispherical portion, passing through the first body, and extending almost to the fixed end of the cable.
