This is an OK example of a late Super Champion Super Mondial. Some of its features include:

• It is a 3-speed model with, for the avoidance of doubt, '3 Vitesses' stamped on its outer pulley cage plate.
• The hole for the dropout bolt is keyhole shaped to accept one of Super Champion's distinctive shaped dropout bolt and nut arrangements that allow a modicum of rotation.
• The chain tension adjustment ring is made of some kind of white metal that oxidises to a dull grey.
• The pulley cage is 47mm long.
• The outer pulley cage plate is also made of some kind of white metal that oxidises to a dull grey.
• The inner pulley cage plate is thin steel and is shaped so that the pulley bolt nuts are recessed.
• The pulley bolts have domed heads and mount from the outside inwards.
