Abstract

Thrust piece for rotating roller reel system of gear changes for cycles, and gear changes thus equipped, characterized by a peripheral extension of the end of the plate that is closest to the freewheel sprockets. This extension extends over a wide sector along which the chain can be in support and be pushed very close to the sprockets of increasing diameters, whatever the angular position of the winder system; Said extension has along the edge in the form of and on the thrust side on the chain, a profiled support width for the chain.
