Peugeot Prestige (SX410)

Peugeot Prestige derailleur (SX410) main image

This Peugeot derailleur is a Simplex Prestige travelling under an alias. It looks thoroughly metal, with its cast aluminium knuckles and all - but in fact the main structural elements of the parallelogram arms are plastic - the metal is somewhat optimistically referred to as ‘stiffening’.

This derailleur illustrates one of the defining oddities of the Simplex Prestige - the more exotic (and expensive) the model - the greater the weight.
